Ultimate Wishlist vs. Sirius Wish: An In-Depth Comparison

Introduction

Choosing the right wishlist app is a deceptively important decision for an online store. A wishlist can drive repeat visits, reduce cart abandonment, and surface product demand, but the wrong implementation can add technical debt and fragment customer data. Merchants must weigh features, limits, and long-term value rather than picking a tool solely on price.

Short answer: Ultimate Wishlist is a polished, focused wishlist tool that delivers strong customization and low-cost plans for stores that only need wishlist functionality. Sirius Wish positions itself as a straightforward wishlist that emphasizes sessions and action limits, but it currently lacks review history and marketplace confidence (0 reviews). For merchants who want to avoid adding single-purpose tools and build retention as a competitive advantage, an integrated platform like Growave offers better value for money by combining wishlist features with loyalty, referrals, and reviews.

This article provides an in-depth, feature-by-feature comparison of Ultimate Wishlist (Config Studio) and Sirius Wish (Sirius Boost LTD.). It uses available product data — including review counts, ratings, pricing tiers, and feature descriptions — to highlight strengths, trade-offs, and ideal use cases. After the direct comparison, the piece explains why consolidating retention tools into a single platform can remove friction and improve lifetime value, with a practical look at how Growave approaches that problem.

Ultimate Wishlist vs. Sirius Wish: At a Glance

Deep Dive Comparison

Product Positioning and Market Signals

Ultimate Wishlist: Focused, Mature, and Reviewed

Ultimate Wishlist is positioned as a fully customizable wishlist solution that supports guest and account-based wishlists, social sharing, email reminders, and a dashboard with wishlist analytics. The app has 34 reviews and a 4.9 average rating, which signals a reasonable level of merchant adoption and positive user experience in its niche.

Key product positioning points:

• Emphasis on customization: text and color, non-English support.
• Analytics-driven: reports on wishlist adds, page views, and added-to-cart conversions.
• Guest wishlist and cross-device persistence for logged-in users.
• Email reminder functionality on paid tiers.
• Social sharing (Facebook, Twitter, Email).

These signals indicate a product built for merchants who prioritize control over the wishlist experience and insight into product demand.

Sirius Wish: Simple, Capacity-Focused, Early Stage

Sirius Wish frames itself as an easy way to let customers save items for later and reduce cart abandonment. The app lists session quotas and wishlist action limits across plans. At the time of this comparison, Sirius Wish shows 0 reviews and a 0 rating in the Shopify listing, which suggests either a very recent launch or low adoption.

Key product positioning points:

• Simplicity and ease of use.
• Session-based scaling (the free tier advertises 6000 sessions).
• Pricing ramps that focus on action quotas rather than item counts or reminders.

Because public feedback is not yet available, merchants should view Sirius Wish as an early-stage alternative. The lack of reviews means less marketplace trust and fewer community-sourced answers to practical problems.

Core Wishlist Features

Add/Remove & Saved Items

Ultimate Wishlist

• Supports wishlist creation with or without registration, meaning merchants can capture intent from both guests and logged-in customers.
• Syncs across devices for logged-in users, so wishlists persist when customers switch devices.
• Offers clear limits on how many items can be stored per month depending on plan (500 to 10,000).

Sirius Wish

• Allows basic add, remove, and manage functions.
• Focuses on wishlist actions and sessions as usage metrics rather than explicit item counts per month. This is useful when traffic patterns are more relevant than stored item totals.

Practical takeaway: For stores that want wishlists to persist and be available across devices and accounts, Ultimate Wishlist’s guest + logged-in flow is stronger. For stores with high anonymous sessions but fewer long-lived wishlist entries, Sirius Wish’s session model might be more attractive.

Sharing & Social

Ultimate Wishlist

• Enables sharing via Facebook, Twitter, and Email out of the box.
• Share functionality helps drive referral traffic and social proof when customers show items to friends and family.

Sirius Wish

• The core description highlights saving items for later, but social sharing is not prominently listed in the product description provided.

Practical takeaway: If social sharing and referral-style uses of wishlists are important (gifting, group buying), Ultimate Wishlist is the safer choice.

Customization & Localization

Ultimate Wishlist

• Offers customizable text and color to match store design.
• Non-English support is explicitly listed, which is helpful for international merchants.

Sirius Wish

• Described as easy to integrate, but customization options and localization details are not prominent in the listing.

Practical takeaway: Merchants running multilingual or highly-branded storefronts will find better on-brand behavior from Ultimate Wishlist.

Reminders & Email Automation

Ultimate Wishlist

• Paid plans introduce customizable email templates and reminders: Basic includes up to 500 reminders/month, Pro and Premium increase reminder volumes and add individual user reminders.
• Reminder automation can turn passive intent into purchases by nudging customers when stock or promotions change.

Sirius Wish

• No email reminder capability is listed in the provided feature set.

Practical takeaway: Email reminders are a conversion lever. Merchants wanting to recover wishlist intent with automated emails should favor Ultimate Wishlist.

Analytics & Reporting

Ultimate Wishlist

• Promotes a dashboard with analytics such as wishlist add, page view, and added-to-cart metrics.
• These insights enable merchandising decisions: promoting high-intent items and identifying popular variants.

Sirius Wish

• The public description references "valuable insights" but no specific dashboard or reporting details are provided.

Practical takeaway: Ultimate Wishlist is clearer on reporting. Merchants who want concrete wishlist-derived signals will find it more actionable.

Pricing and Value

Deciding on value requires looking beyond price to limits and growth trajectory. Each app uses a different currency for capacity.

Ultimate Wishlist Pricing Structure

• Free: Up to 500 wishlist items/month, guest wishlist, sharing, customizable text/colors, non-English support, and reporting.
• Basic ($4.99/mo): Everything in Free + up to 1,000 items/month, custom email template, up to 500 email reminders/month.
• Pro ($9.99/mo): Everything in Basic + send email reminders to individual users, up to 5,000 items/month, up to 2,000 reminders/month.
• Premium ($14.99/mo): Everything in Pro + up to 10,000 items/month, up to 5,000 reminders/month, Facebook Pixel integration.

How to evaluate value:

• For small stores with light wishlist use, the free plan or Basic tier offers strong features at a low price.
• Reminder volumes and item limits scale reasonably with price — the gap between Pro and Premium is relatively small compared to the extra capacities gained.
• Facebook Pixel in Premium is useful for remarketing based on wishlist behavior.

Sirius Wish Pricing Structure

• Free: 6,000 sessions and 100 wishlist actions.
• Starter ($14.99/mo): 12,000 sessions and 1,500 wishlist actions.
• Pro ($49.99/mo): 60,000 sessions and 15,000 wishlist actions.
• Premium ($89.99/mo): 110,000 sessions and 60,000 wishlist actions.

How to evaluate value:

• Sirius Wish targets stores with high session counts; the free tier’s 6,000 sessions may be generous for low-traffic stores.
• The distinction between sessions and wishlist actions matters: a single visitor session can represent multiple wishlist actions or none.
• At higher tiers, Sirius Wish becomes materially more expensive than Ultimate Wishlist but scales capacity dramatically.

Practical pricing comparison: Ultimate Wishlist is priced for broad accessibility and low entry cost. Sirius Wish scales by traffic and actions, which could be cost-effective for stores with many anonymous sessions but low wish counts. Merchants should do a simple math model: estimate monthly sessions, wishlist actions, and desired features (email reminders, sharing, analytics) before choosing.

Important note about value: “Better value for money” is context-dependent. Ultimate Wishlist offers more merchant-facing features at lower price points; Sirius Wish provides a capacity model that can be attractive for specific traffic profiles. If a merchant needs wishlist analytics and reminder automation, Ultimate Wishlist offers better apparent value.

Integrations & Ecosystem Compatibility

Third-Party Integrations

Ultimate Wishlist

• Lists Facebook Pixel integration on the Premium plan.
• Works across customer accounts and supports shared wishlist flows for logged-in users.

Sirius Wish

• No explicit third-party integrations or extended ecosystem compatibility presented in the listing.

Why integrations matter:

• Integrations enable wishlist data to feed email, ads, and support systems. Facebook Pixel enables remarketing to wishlist users; email platforms can use wishlist data for targeted campaigns.
• Stores with existing tech stacks should prioritize apps that integrate with email (Klaviyo, Omnisend), support platforms (Gorgias), and commerce workflows (Recharge, Shopify POS).

Practical takeaway: Ultimate Wishlist’s Facebook Pixel integration is a practical advantage. The lack of listed integrations for Sirius Wish is a potential blocker for merchants who need deeper data movement.

Platform Compatibility & Scale

Ultimate Wishlist

• Supports guest wishlists and logged-in user persistence — useful for stores that mix account-based and guest checkout models.
• Item-per-month limits could be a constraint for very large catalogs or campaigns that spike wishlist usage.

Sirius Wish

• Session-based model means it is tuned for traffic-driven scaling, which may align with stores that prioritize anonymous browsing.

Practical takeaway: Consider whether the store relies on customer accounts. If cross-device persistence and account-based personalization matter, Ultimate Wishlist is preferable.

User Support and Marketplace Confidence

Reviews & Public Feedback

Ultimate Wishlist

• 34 Shopify reviews, 4.9 rating. That level of positive reviews is an encouraging marketplace signal: merchants report satisfaction and the app has been tested in actual stores.

Sirius Wish

• 0 reviews, 0 rating. This absence makes it hard to judge real-world reliability, customer support responsiveness, or edge-case behavior.

Why this matters:

• Review counts and ratings directly affect hiring confidence. Apps with higher review volumes reduce the risk of unknown issues and provide problem-solving signals discovered by peers.

Practical takeaway: A merchant can reasonably expect fewer unknowns with Ultimate Wishlist due to public review data.

Support Options & Documentation

Ultimate Wishlist

• Provides customizable email templates and business-facing features; support responsiveness is typically inferred from positive reviews but merchants should review the app listing for documented SLAs.

Sirius Wish

• Support availability, response times, and documentation are not prominent in the listing. Merchants considering Sirius Wish should contact the developer to clarify support expectations and SLAs before installing.

Practical takeaway: Ask for support examples and escalation paths before committing, especially if the app will touch customer accounts or send emails.

Implementation, Performance, and UX

Installation & Theme Compatibility

Ultimate Wishlist

• Marketed as easily customizable to match store appearance. Merchants will still need to test the wishlist UI across themes and mobile.

Sirius Wish

• Promises easy integration, but there are fewer details about theme-level customizations.

Practical takeaway: Both apps appear installable without heavy development, but merchants that require pixel-perfect UI alignment should test both on a staging theme before going live.

Performance Impact

• Any wishlist app that inserts JavaScript or makes server calls can affect page load if not optimized.
• Ultimate Wishlist’s analytics, reminders, and Facebook Pixel options introduce additional scripts or server-side events.
• Sirius Wish’s session model suggests some client-side tracking as well.

Practical takeaway: Monitor Lighthouse / Core Web Vitals after installation. If page speed is a priority, request the app developer’s guidance for asynchronous script loading and deferred resources.

Data Ownership and Portability

• Merchants should verify how each app stores wishlist data, whether exports are available, and how data is handled on uninstall.
• Ultimate Wishlist’s reporting and email reminder features imply server-side storage of lists and contact details; confirm GDPR/compliance procedures.
• Sirius Wish’s session-based approach may place a different emphasis on transient data; confirm what happens to wishlists after plan changes or uninstalls.

Practical takeaway: Always request a data export process before committing. Ensure the app vendor provides CSV/JSON exports of wishlist events and user lists.

Use Cases and Recommendations

Below are practical recommendations based on common merchant profiles.

• Stores that want a low-cost, feature-rich wishlist with email reminders and analytics:
  • Ultimate Wishlist is a strong fit. The free tier covers light traffic; paid tiers add reminders and pixel integration.
  • Ideal for small to mid-size brands focused on converting wishlist intent into purchases via email and social sharing.
• Stores with high anonymous traffic and a need for session-aware capacity:
  • Sirius Wish’s session and wishlist action model could be useful, especially if anonymous browsing is the dominant behavior.
  • Because Sirius Wish has no public reviews yet, conduct a pilot and validate support before committing to a paid tier.
• Global stores requiring localization and brand-level customization:
  • Ultimate Wishlist explicitly lists non-English support and UI customization, making it a safer choice out of the box.
• Stores seeking a single vendor to manage multiple retention levers:
  • Both Ultimate Wishlist and Sirius Wish are single-function apps. Merchants that want to consolidate loyalty, reviews, referrals, and wishlist into a unified strategy should evaluate multi-feature platforms.

Migration Considerations

• Migrating wishlist data between apps can be non-trivial. If switching in the future, plan to export wishlist data, update theme components, and verify user-facing links.
• Merchants that expect to expand into loyalty or referral programs should plan for cross-tool data synchronization. Single-purpose wishlist apps will not cover these needs, requiring additional integrations later.

The Alternative: Solving App Fatigue with an All-in-One Platform

App fatigue is a real operational cost. Adding multiple single-purpose apps (one for wishlists, another for loyalty, another for reviews) increases maintenance, installation complexity, redundant scripts, and fragmented customer data. Each extra app adds user interface inconsistencies and potential compatibility issues. For merchants focused on retention and lifetime value, consolidation can reduce complexity and produce better outcomes.

Growave’s philosophy—More Growth, Less Stack—addresses this directly. Instead of stitching together separate wishlist and loyalty tools, a merchant can use an integrated retention suite that connects wishlists to loyalty, referrals, reviews, and VIP tiers. That approach reduces tool sprawl and keeps customer intent data centralized.

Why consolidation matters in practice:

• Centralized data lets wishlists feed loyalty and triggered emails without custom integrations.
• Unified UX across loyalty, wishlist, and reviews reduces friction for customers and simplifies store theming.
• Fewer third-party scripts can improve performance and reduce the risk of conflicts.

Growave bundles wishlist capabilities into a broader retention platform that includes loyalty and rewards, referrals, and review collection. For merchants evaluating the trade-offs between single-purpose apps and integrated suites, the following points illustrate practical differences.

How Growave Reduces Operational Overhead

• Centralized retention data: Wishlists collected in the same platform that manages loyalty points and referrals produce clearer customer profiles and enable targeted promotions.
• Fewer integrations to maintain: When wishlist behavior needs to trigger points or VIP tier changes, an integrated system avoids brittle webhooks and custom middleware.
• Unified support and roadmap: A single vendor for multiple retention tools streamlines support and feature requests, while single-purpose vendors often address only one product’s roadmap.

Growave Feature Alignment (Core Capabilities)

Growave is built to combine several retention functions into one suite. Key capabilities include:

• Loyalty programs and rewards
  • Merchants can design point-based programs, set custom reward actions, and create VIP tiers.
  • See how Growave enables loyalty and rewards that drive repeat purchases.
• Wishlist functionality
  • Wishlist is available as a first-class feature inside the platform, linked to customer profiles and reward logic.
  • Wishlist events can be used to trigger rewards or segment customers for campaigns.
• Reviews and user-generated content
  • Collect and display reviews, integrate photo reviews, and use review data in merchandising.
  • Merchants can learn how to collect and showcase authentic reviews.
• Referrals and VIP tiers
  • Referral incentives and VIP tiers tie directly into purchase behavior and wishlist signals.
• Shopify Plus compatibility and enterprise features
  • For high-growth stores, Growave offers solutions for high-growth Plus brands with advanced integrations and dedicated support.

Because wishlist events live next to loyalty and reviews, marketers can design campaigns like rewarding points for adding items to a wishlist or sending tiered reminders to VIP customers.

Real-World Benefits Compared to Single-Purpose Apps

• Better LTV per customer: When wishlist behavior is used to deliver personalized rewards and review prompts, average order value and repeat purchase rate can increase.
• Fewer vendor relationships: One vendor relationship reduces administration time and leads to a more consistent roadmap that connects wishlist, loyalty, and reviews.
• Unified analytics: A single analytics view that crosses wishlist adds, reward redemptions, and referrals provides clearer ROI measurements.

Pricing and Scalability — Practical Comparison

Growave’s pricing is tiered to match store scale and feature needs. The platform provides a free plan and paid plans that include more advanced customization, integrations, and support.

• The Entry plan ($49/mo) bundles loyalty, wishlist, referrals, and reviews at a price comparable to installing multiple single-purpose apps.
• Growth and Plus plans scale with business needs and add advanced integrations, priority support, and enterprise-grade features.

For merchants comparing total cost of ownership, consider the combined monthly fees of a wishlist app plus a loyalty app plus a reviews app. Consolidating into one platform often results in better long-term value.

Merchants can evaluate plans and determine which package fits growth objectives by reviewing pricing to consolidate retention features. Additionally, to see the integrated app listing and install directly, merchants can install Growave from the Shopify App Store.

Integration Examples and Ecosystem Connections

Growave integrates with common stack components that merchants already use:

• Email & automation: Klaviyo, Omnisend
• Helpdesk: Gorgias
• Subscriptions: Recharge
• Messaging & push solutions: Postscript, PushOwl
• Page builders: Pagefly, LayoutHub, GemPages
• Plus/enterprise tools and headless workflows supported via API and SDK

If a merchant needs enterprise-level support and integrations for large, complex setups, Growave provides tailored solutions for high-growth Plus brands. The ability to centralize wishlist data and use it across email and support improves both marketing efficiency and post-purchase support.

Why Merchants Move From Single Apps to Integrated Platforms

Common triggers to migrate include:

• Difficulty reconciling customer identity across multiple apps.
• The need to reward wishlist behavior with loyalty points or VIP status.
• Performance or theme conflicts caused by multiple inserted scripts.
• Desire for a single support channel and consistent roadmap.

To evaluate whether consolidation makes sense, compare the combined monthly cost of your single-purpose tools against one integrated platform and weigh the operational savings of fewer integrations.

A helpful next step for merchants who want a tailored assessment is to install Growave from the Shopify App Store and test the combined features in a sandbox environment, or to consolidate retention features and see the pricing tiers laid out.

Case Examples (Generalized Actions Merchants Can Take)

• If a merchant’s wishlist adds rarely convert, configure wishlist reminder emails and A/B test subject lines and timing to increase conversions (Ultimate Wishlist supports reminders; integrated suites let reminders be linked to loyalty).
• If a store sees strong anonymous browsing but low account signups, test Sirius Wish’s session model on a pilot theme and measure wishlist action rates versus account-linked persistence.
• If a brand wants to turn wishlist activity into repeat business, set wishlist add actions to grant small loyalty points and then promote rewards in cart or on the loyalty widget—something a unified platform handles without complex middleware.

Which App Is Best For Which Merchant?

No single app is objectively superior in every context. The right choice depends on practical variables.

• Best for merchants who need a focused, low-cost wishlist with reminders, analytics, and social sharing:
  • Ultimate Wishlist. It offers customization, clear reporting, guest and account support, and automated reminders at accessible price points.
• Best for merchants with high anonymous traffic and a need for session-based scaling:
  • Sirius Wish. The session/action pricing model could be economical for stores that generate many sessions but modest wishlist actions. However, proceed with caution due to the lack of public reviews.
• Best for merchants who want consolidated retention across wishlist, loyalty, and reviews:
  • Growave. By unifying wishlist with loyalty, referrals, and reviews, Growave reduces the number of apps to maintain and lets wishlist actions directly feed loyalty and review workflows.

Conclusion

For merchants choosing between Ultimate Wishlist and Sirius Wish, the decision comes down to priorities. Ultimate Wishlist is an excellent choice for stores that want a customizable wishlist experience with email reminders and analytics at an affordable price. Sirius Wish may fit stores that prioritize session-based capacity and are comfortable evaluating a newer app with no public reviews yet.

Beyond the single-purpose choice, consider whether wishlist behavior is an isolated tactic or part of a broader retention strategy. If wishlists are one input among loyalty, referrals, and reviews, consolidating into an integrated platform reduces tool sprawl and improves long-term retention. Growave’s suite combines wishlist functionality with loyalty and rewards, referrals, and reviews so that wishlist events can be used strategically to increase lifetime value.

FAQ

How does Ultimate Wishlist differ from Sirius Wish on daily merchant usage?

Ultimate Wishlist emphasizes customization, non-English support, social sharing, and automated email reminders; it has public user feedback (34 reviews, 4.9). Sirius Wish focuses on session and wishlist-action capacity with tiered limits and is positioned as simple to integrate. Merchants that need reminders, analytics, and sharing will find Ultimate Wishlist richer; merchants prioritizing session-aware capacity might find Sirius Wish’s pricing model aligned to their traffic, but the lack of reviews requires extra validation.

Which app offers better value for money for a small to mid-size store?

For small to mid-size stores that want analytics and email reminders, Ultimate Wishlist appears to offer better value for money because of lower-priced tiers with features that directly drive conversions. Sirius Wish’s free and starter tiers are oriented around sessions and actions and may be cost-effective if the store’s traffic profile fits those caps.

Can wishlist behavior be used to improve loyalty and repeat purchases?

Yes. When wishlist adds are connected to loyalty mechanics (for example, awarding points for adding items or creating VIP segments based on wishlist activity), wishlist behavior becomes a conversion lever. Single-purpose wishlist apps require extra integrations to trigger loyalty actions; an integrated platform lets merchants tie wishlist events directly to rewards and referral logic. Merchants can explore how to combine wishlist and rewards to loyalty and rewards that drive repeat purchases.

How does an all-in-one platform compare to specialized apps?

An all-in-one platform reduces complexity by centralizing wishlist, loyalty, referrals, and reviews. This simplifies data flows, reduces the number of third-party scripts, and enables cross-feature campaigns without custom middleware. The trade-off can be slightly higher entry pricing in some cases, but the operational savings and increased LTV often outweigh the cost. Merchants can learn about integrated review capabilities and social proof by reviewing how to collect and showcase authentic reviews and reading customer stories from brands scaling retention.
