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

Introduction

Choosing the right wishlist app is a deceptively important decision for Shopify merchants. A wishlist can boost conversions, reduce cart abandonment, and surface product demand, but each app approaches those goals differently. Merchants must weigh functionality, integration, cost, and the long-term effects of adding yet another single-purpose tool to their tech stack.

Short answer: Ultimate Wishlist is a focused, lightweight wishlist tool with strong ratings and a straightforward pricing ladder that suits merchants who need a reliable, low-cost wishlist feature. Sirius Wish presents itself as a modern wishlist offering with session-based plans aimed at higher volume stores, but its lack of public reviews and unclear real-world signals increases implementation risk. For stores that want to stop juggling single-use apps and invest in retention and lifetime value, an integrated platform like Growave can provide better value for money by consolidating wishlist, loyalty, reviews, and referrals into one system.

This post compares Ultimate Wishlist (Config Studio) and Sirius Wish (Sirius Boost LTD.) feature by feature — including pricing, integrations, analytics, and support — so merchants can choose the right tool for their goals. After the head-to-head analysis, the article explains how an all-in-one retention platform addresses common limitations of single-purpose apps.

Ultimate Wishlist vs. Sirius Wish: At a Glance

Deep Dive Comparison

Features

Core Wishlist Functionality

Ultimate Wishlist:

• Offers classic wishlist functionality with both account-linked and guest wishlists. Customers can create lists without logging in, then optionally migrate or link to an account, which lowers friction during early discovery.
• Supports cross-device synchronization for logged-in users, ensuring lists persist across sessions and devices.
• Built-in sharing via Facebook, Twitter, and email makes social proof and gift sharing straightforward.
• Includes non-English support and customizable text so stores can localize copy and UI.

Sirius Wish:

• Focuses on wishlist creation and management, enabling customers to add, remove, and curate items.
• Appears to emphasize "save-for-later" behavior and reducing cart abandonment.
• Uses session-based quotas in pricing (sessions and wishlist actions), which implies tracking by traffic and activity more than by user accounts.

Analysis: Ultimate Wishlist provides a standard wishlist feature set that matches merchant expectations: guest lists, account sync, and social sharing. Sirius Wish positions itself similarly but emphasizes sessions and actions rather than user accounts, which may affect merchants who rely on logged-in UX or require persistent account histories.

Customization & Branding

Ultimate Wishlist:

• Allows customization of text and appearance to match store branding. This includes color and label edits and full non-English text support.
• Customizable email templates (in paid tiers) let merchants control reminder messaging and timing.

Sirius Wish:

• Product descriptions emphasize an intuitive experience and seamless integration, but public details on the depth of visual customization are limited.
• Merchants should verify if theme-native styling and layout hooks are available to maintain consistent brand appearance.

Analysis: For merchants who prioritize brand consistency and multilingual stores, Ultimate Wishlist’s explicit non-English support and text customization are clear advantages. Sirius Wish may offer adequate styling, but the lack of detailed documentation and public reviews makes it harder to assess without testing.

Sharing, Social, and Reminders

Ultimate Wishlist:

• Built-in sharing options (Facebook, Twitter, Email).
• Email reminders in Basic/Pro/Premium tiers: customizable templates and varying monthly reminder quotas depending on plan level.

Sirius Wish:

• Stresses the ability to save products for later and reduce cart abandonment. It does not explicitly advertise email reminder quotas or social sharing in the provided description.

Analysis: Ultimate Wishlist provides explicit sharing and reminder mechanisms that help re-engage customers. For merchants who want wishlist-based email reminders baked into the wishlist app, Ultimate Wishlist is more transparent. Sirius Wish’s focus seems to be on the on-site experience and analytics; if external follow-ups are critical, confirm Sirius Wish’s capabilities before committing.

Analytics & Reporting

Ultimate Wishlist:

• Offers a dashboard with analytics for wishlist adds, page views related to wishlist, and items added to cart. That reporting helps merchants identify demand for specific SKUs or variants.
• Higher tiers expand ability to track individual reminder sends and potentially user-level behaviors.

Sirius Wish:

• The marketing copy mentions providing "valuable insights into customer preferences," but lacks explicit detail on the type and depth of analytics available (events, conversion funnels, or exported data).

Analysis: Ultimate Wishlist’s reporting is explicit and actionable. Sirius Wish may have analytics but the lack of public specifics increases ambiguity. Merchants that need concrete product demand signals should prioritize the app that exposes clear metrics or offers easy data export.

Multi-Device & Account Support

Ultimate Wishlist:

• Supports wishlists with or without registration and ensures logged-in users see wishlists across devices.

Sirius Wish:

• The description suggests typical wishlist behavior but doesn’t explicitly outline cross-device sync or account-based persistence.

Analysis: Persistent wishlists tied to customer accounts are valuable for lifetime value and re-engagement. Ultimate Wishlist documents this capability; Sirius Wish should be validated for cross-device consistency.

Pricing & Value

Pricing is about more than sticker cost. It reflects usage profile, support, and long-term value.

Ultimate Wishlist Pricing Overview

• Free: Up to 500 wishlists/month, guest wishlist, collection page wishlist, sharing, customizable text/color, non-English support, full reports.
• Basic ($4.99/month): Adds up to 1,000 wishlist items/month, custom email template, up to 500 email reminders/month.
• Pro ($9.99/month): Up to 5,000 wishlist items/month, send email reminders to individual users, up to 2,000 reminders/month.
• Premium ($14.99/month): Up to 10,000 wishlist items/month, up to 5,000 reminders/month, Facebook pixel integration.

Value factors:

• Clear, low-price entry point. Suitable for stores with moderate wishlist volume.
• Email reminders and pixel integration in higher tiers provide direct conversion pathways.
• Transparent caps on wishlist items and reminders help merchants predict cost as use scales.

Sirius Wish Pricing Overview

• Free: 6000 Sessions, 100 wishlist actions.
• Starter ($14.99/month): 12,000 Sessions, 1,500 wishlist actions.
• Pro ($49.99/month): 60,000 Sessions, 15,000 wishlist actions.
• Premium ($89.99/month): 110,000 Sessions, 60,000 wishlist actions.

Value factors:

• Pricing is session- and action-based, which can be efficient for large-traffic stores if session counts align with actual wishes.
• Higher tiers are more expensive; Pro and Premium are significantly pricier than Ultimate Wishlist’s top plan.
• The free tier provides many sessions but only 100 wishlist actions, which caps actual wishlist use. For high-traffic stores, the session model may not map well to wishlist activity patterns.

Analysis: Ultimate Wishlist is priced to serve small to mid-sized merchants with predictable monthly caps. Sirius Wish targets stores that want session-scaled pricing, but costs scale quickly. The session model can become expensive and somewhat opaque because sessions are not the same as wishlist actions. Merchants that prefer predictable pricing tied directly to wishlist usage may find Ultimate Wishlist to be better value for money.

Integrations & Ecosystem

Ultimate Wishlist:

• Lists Facebook pixel integration at Premium, which helps connect wishlist behavior to ad audiences and conversions.
• Works in the typical Shopify environment; merchants can combine its outputs with external analytics.

Sirius Wish:

• Marketing copy claims effortless Shopify integration but does not list third-party integrations, email platform connectors, or analytics hooks.

Analysis: Integration transparency matters. Without explicit integration lists, Sirius Wish requires merchants to test or ask the developer about connections to email marketing (Klaviyo, Omnisend), analytics platforms, or tag managers. Ultimate Wishlist’s Facebook pixel support is clearly stated, which helps ad attribution and retargeting.

Implementation & UX

Ultimate Wishlist:

• Designed to be simple to install and configure with customizable text/appearance to match theme styling.
• Guest wishlist support reduces friction for first-time shoppers.
• Email templates and reminders require configuration but are standard features.

Sirius Wish:

• Described as easy to integrate and intuitive for end customers.
• Session quota approach implies a focus on performance and analytics rather than onboarding complexity.

Analysis: Both apps promote easy integration. Ultimate Wishlist’s established presence and explicit settings make implementation predictable. Sirius Wish’s novelty and lack of public reviews add a layer of uncertainty about developer responsiveness and edge-case issues (e.g., theme conflicts).

Support & Documentation

Ultimate Wishlist:

• Has a history of reviews (34) and a high rating (4.9), which often indicates responsive support and a stable product.
• Pricing tiers suggest email reminder quotas and pixel integration — implying the developer maintains active development.

Sirius Wish:

• Zero reviews and a 0 rating are not necessarily a reflection of product quality but do remove public evidence of support quality and real merchant experiences.
• Merchants should request support SLA details before committing to paid plans.

Analysis: Public feedback helps anticipate support quality. Ultimate Wishlist’s reviews and rating are an advantage. Sirius Wish requires merchants to validate response times, update cadence, and documentation availability.

Analytics, Data Ownership & Reporting

Ultimate Wishlist:

• Provides in-app reporting on wishlist adds, page views, and items added to cart. That helps merchants evaluate which products drive wishlist interest and convert into purchases.
• Higher tiers include more granular reminder capabilities.

Sirius Wish:

• Mentions insights into customer preferences but lacks specifics about export, event tracking, or conversion funnels.

Analysis: Merchants often rely on wishlist data to inform merchandising and inventory decisions. An app that provides accessible metrics and the ability to export raw data or integrate with BI tools is preferable. On that metric, Ultimate Wishlist is currently more transparent.

Security, Compliance & Data Retention

Neither app’s provided data directly lists security practices. Merchants should verify:

• How wishlist data is stored and retained.
• Whether personal data in guest wishlists is handled in compliance with GDPR and other privacy regulations.
• Where backup and export functions are available.

Recommendation: Before installation, request the developers’ privacy documentation and data retention policies, especially if guest wishlists collect emails or personally identifiable information.

Performance & Scalability

Ultimate Wishlist:

• Suited to small and medium traffic stores with predictable plan caps.
• Premium plan scales to 10,000 wishlist items/month, which satisfies most SMB needs.

Sirius Wish:

• Session-based pricing suggests intent to scale with traffic; premium plans go up to 110,000 sessions and 60,000 wishlist actions.
• For very high-traffic stores that generate many sessions but fewer wishlist actions, Sirius Wish may be cost-efficient if the ratios align.

Analysis: Scalability decisions depend on traffic patterns. Assess historical analytics: if sessions are high relative to wishlist actions, the session-based model may be wasteful or expensive. Conversely, if high sessions correlate with high wishlist activity, Sirius Wish could be appropriate. With Ultimate Wishlist, merchants get clearer wishlist item caps rather than sessions, which directly maps to the feature usage.

Real-World Signals: Reviews & Ratings

• Ultimate Wishlist: 34 reviews, 4.9 rating. This is a strong signal of product satisfaction and reliability among merchants who have used and rated the app.
• Sirius Wish: 0 reviews, 0 rating. The absence of reviews introduces more implementation risk; merchants lack community feedback and must rely on private testing or vendor responses.

Analysis: Public reviews are a practical proxy for stability and support. The difference here is material: a 4.9 app with dozens of reviews demonstrates consistent merchant adoption and satisfaction. The lack of reviews for Sirius Wish means a merchant should test thoroughly or pilot the app before rolling it out.

Pros & Cons Summary

Ultimate Wishlist — Pros:

• High public rating (4.9) and positive developer signal.
• Clear, low-cost pricing tiers with transparent usage caps.
• Guest and account-based wishlists with cross-device sync.
• Built-in sharing and reminder features; non-English support.

Ultimate Wishlist — Cons:

• Feature set focused on wishlist-only functionality; merchants needing loyalty or reviews must add other apps.
• Advanced segmentation or deeper retention flows may require integrations.

Sirius Wish — Pros:

• Session-based pricing for stores that prefer traffic-aligned cost models.
• Appears to prioritize on-site experience and reduction of cart abandonment.

Sirius Wish — Cons:

• No public reviews; rating = 0 increases adoption risk.

  • The merchant wants a proven wishlist solution with transparent pricing and public ratings.
  • Localization and simple email reminders are needed.
  • The store prefers predictable, wishlist-specific usage caps rather than session-based billing.
  • Budget sensitivity is high and wishlist needs are straightforward.
• Choose Sirius Wish If:
  • Traffic patterns and session-to-wishlist ratios have been analyzed and align with Sirius Wish’s session-based pricing.
  • The merchant prefers a potential high-volume wishlist plan and is willing to pilot the app due to lack of public reviews.
  • The store wants to emphasize session-based tracking and is prepared to validate integrations and customization during implementation.

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

Single-purpose apps can solve an immediate need but introduce two recurring problems: tool sprawl and fractured customer data. Each additional app increases theme maintenance, slows page speed, and fragments metrics across vendor dashboards. This leads to "app fatigue" — the cumulative cost, complexity, and overhead of managing many point solutions.

An integrated retention platform addresses these issues by centralizing wishlist, loyalty, reviews, and referrals under one roof. Growave’s philosophy — More Growth, Less Stack — focuses on reducing tool sprawl and increasing the lifetime value of customers through connected retention features.

Growave integrates wishlist functionality with other retention tools to produce compounding outcomes:

• Wishlist activity feeds into loyalty incentives, so wishlist adds can trigger targeted reward nudges.
• Wishlist signals can populate UGC and review workflows, turning intent into social proof.
• Consolidated reporting surfaces how wishlist behavior interacts with repeat purchase rates.

Merchants can review plans and decide whether combining tools into one platform is a better investment than many single-purpose apps. To evaluate pricing and plans, merchants can assess how much value comes from consolidated features and compare monthly costs with the combined cost of multiple apps. For a direct look at plan details and the 14-day free trial, merchants can compare options for consolidating retention features with Growave’s pricing.

Growave’s suite includes integrated modules that solve typical wishlist limitations:

• Loyalty and rewards to convert wishlist interest into repeat purchases and increase LTV. See how merchants build loyalty and rewards that drive repeat purchases.
• Reviews & UGC to collect and amplify authentic customer content and turn wishlist interest into trusted social proof. Learn how to collect and showcase authentic reviews.
• Wishlist features that work alongside loyalty and referrals so wishlist adds aren’t siloed but become triggers for targeted re-engagement.
• Plus-level services and customizations for enterprise merchants, including headless API options and dedicated launch support for complex stores.

Merchants considering a consolidated solution should explore implementation options and real brand examples to see how integrated stacks change outcomes. Growave provides customer stories and inspiration that reveal how brands reduce churn and raise average order value. For merchants evaluating platform-level migration, reading customer stories from brands scaling retention helps illustrate real outcomes.

Why consolidation matters:

• Operational simplicity: One integration, one support channel, and one unified data model reduce management overhead compared to maintaining separate wishlist, loyalty, and review apps.
• Cross-functional automation: Wishlist triggers can automatically enroll customers into reward flows or prompt social proof collection, creating automated retention loops that single apps rarely provide.
• Unified analytics: Seeing wishlist behavior, reward redemptions, and review influence on repeat purchases in one dashboard enables smarter merchandising and campaign decisions.

Growave supports merchants at different scales:

• Small merchants can start on lower tiers and still get cross-functional benefits from combined wishlist and basic loyalty.
• Growth-stage stores benefit from advanced customization and integrations that allow loyalty pages, checkout extensions, and API-based headless storefronts.
• Enterprise and Shopify Plus merchants have access to dedicated support and custom launch plans designed to match complex operational needs — which is especially important for stores migrating from several single-purpose apps.

For a direct evaluation:

• Merchants who want to see a tailored comparison and how Growave reduces their stack can book a personalized demo. This is a practical step for merchants who want a walkthrough showing wishlist behavior tied to loyalty workflows and review automation.

Implementation Checklist: Choosing, Installing, and Testing

When evaluating wishlist apps — whether a single-purpose tool or an integrated platform — use this checklist to reduce risk and measure impact. Each bullet is a decision point to validate during trials or demos.

• Confirm data model: how wishlist items are stored and whether they are tied to customer accounts.
• Export capability: ensure wishlist data can be exported or integrated with marketing platforms.
• Email and push workflows: verify if wishlist reminders integrate with email platforms or are handled by the app.
• Performance testing: test page load impact and script behavior on peak traffic pages.
• Theming and UX: ensure the wishlist UI matches the store’s look and mobile responsiveness.
• Tracking and attribution: confirm pixel support or event hooks for ad attribution and analytics.
• Support SLAs: confirm developer response time expectations and priority support for paid plans.
• Migration path: plan how to migrate existing wishlist data if moving from one app to another.

For merchants considering an integrated approach, test the interplay between wishlist activity and loyalty flows, and review how reviews are captured post-purchase. Merchants can review the suite of features and pricing to decide on consolidation by checking the plan comparison to consolidate retention features and review the app store listing for marketplace context at Growave on the Shopify App Store.

Cost Comparison Example (Hypothetical Calculation Guidance)

Merchants should analyze their own data, but a simple method can reveal which model is more cost-effective:

• Calculate monthly wishlist actions or expected wishlist items based on conversion rate and traffic.
• For Ultimate Wishlist, compare the relevant plan cap against projected wishlist items and email reminder needs.
• For Sirius Wish, map sessions and wishlist action quotas to current GA/analytics data to see which plan aligns.

If the combined cost of a wishlist app plus a separate loyalty or review app exceeds the monthly cost of an integrated platform that delivers similar features, the integrated platform becomes a better value-for-money choice.

Merchants who want a closer fit between wishlist actions and loyalty flows should also compare whether wishlist data can trigger loyalty program enrollment or award points — a capability commonly available in consolidated platforms.

Security, Legal, and Privacy Considerations

When using any wishlist solution, merchants should confirm:

• GDPR compliance and data subject rights support for EU customers.
• Data storage location and retention policies.
• How guest wishlist emails are stored and whether they are shared with third parties.
• Whether cookie or session tracking aligns with privacy consent frameworks.

Ask developers for explicit documentation on privacy, export capability, and data deletion to ensure compliance.

Conclusion

For merchants choosing between Ultimate Wishlist and Sirius Wish, the decision comes down to priorities and risk tolerance. Ultimate Wishlist is a low-cost, well-rated, and transparent wishlist app that fits small-to-mid-size merchants who want predictable pricing, non-English support, and built-in sharing and reminder functionality. Sirius Wish targets traffic-driven stores with session-based pricing and the potential to scale for high-traffic use cases, but the absence of public reviews and limited public detail on integrations and analytics increases the need for careful piloting.

Beyond choosing between single-purpose wishlist apps, many merchants will benefit from consolidating retention features into a single platform. An integrated solution reduces tool sprawl, unifies customer data, and enables behavior-driven retention flows that single-purpose apps cannot deliver on their own. For merchants ready to reduce stack complexity and increase customer lifetime value, Growave offers wishlist functionality alongside loyalty, reviews, referrals, and VIP tiers — a unified approach designed to produce compounding retention effects.

FAQ

What are the main differences between Ultimate Wishlist and Sirius Wish?

• The main differences are pricing model and public signals. Ultimate Wishlist uses wishlist-item quotas and has an established review history (34 reviews, 4.9 rating). Sirius Wish uses session- and action-based pricing and currently lacks public reviews, which makes merchant validation more important. Ultimate Wishlist explicitly documents features like non-English support, cross-device sync, email reminders, and analytics. Sirius Wish emphasizes on-site wishlist management and reducing cart abandonment but requires verification for integrations and reporting depth.

Which app offers better value for money?

• Value depends on store profile. For small to medium stores that want predictable wishlist costs and built-in reminders, Ultimate Wishlist typically offers better value for money. For very high-traffic stores where session-based pricing matches business patterns, Sirius Wish can make sense, but the lack of public reviews raises adoption risk. Merchants should compare total monthly costs, including any additional apps required for loyalty or reviews.

How should merchants decide between a single-purpose wishlist app and an all-in-one retention platform?

• Consider operational overhead, cross-functional automation needs, and long-term retention goals. If the aim is only to enable wishlist saves quickly, a single-purpose app may suffice. If the goal is to convert wishlist signals into repeat customers through loyalty programs, referrals, and review automation, an integrated platform reduces tech complexity and often delivers better long-term ROI. For a side-by-side evaluation of consolidation benefits and plan options, merchants can evaluate how to consolidate retention features.

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

• An all-in-one platform centralizes data and automations, enabling wishlist events to directly trigger loyalty or review workflows without custom integration work. Specialized apps can be best-of-breed for a single function, but they increase maintenance, data fragmentation, and potential theme conflicts. An integrated solution reduces the number of vendors to manage, provides unified reporting, and allows retention strategies to be orchestrated from one system. Merchants evaluating this tradeoff should review consolidated feature sets and the impact on lifetime value metrics, such as repeat purchase rate and average order value. For feature comparisons, merchants can explore how Growave combines wishlist with loyalty and reviews to drive retention by checking how to build loyalty and rewards that drive repeat purchases and how to collect and showcase authentic reviews.
