Smile.io vs Growave: Which Reviews & Loyalty Software is Better for Shopify?
Loyalty programs and product reviews are two of the highest-leverage tools a Shopify merchant can deploy. They drive repeat purchases, boost average order value, and build the kind of social proof that converts browsers into buyers. Two of the most popular platforms in this space — Smile.io and Growave — take notably different approaches to solving these problems.
Smile.io is a dedicated loyalty and rewards specialist, while Growave bundles loyalty, reviews, wishlists, and more into a single all-in-one suite. Which one is better for your store? That depends on your priorities, budget, and growth stage. In this comparison, we break it all down.
Smile.io Overview
Smile.io is one of the most established loyalty platforms in the Shopify ecosystem, powering rewards programs for tens of thousands of merchants worldwide.

Its deep specialization means merchants get granular control over earning rules, redemption options, and program branding.

Growave Overview
Growave markets itself as an all-in-one marketing platform for Shopify, combining loyalty and rewards, product reviews, wishlists, social login, and Instagram-style user-generated content (UGC) galleries into a single app. The value proposition is straightforward: replace multiple single-purpose apps with one unified tool and save on subscription costs.

- Social Login: One-click account creation via Google, Facebook, Amazon, and other providers.
- UGC & Instagram: Curate shoppable Instagram galleries and customer photo feeds directly on-site.

Pricing Comparison
Both platforms offer free plans, but the paid tiers scale differently. Here is a general overview based on publicly listed pricing.
| Plan | Smile.io | Growave |
|---|---|---|
| Free | $0/mo (up to 200 orders) | $0/mo (limited features) |

Loyalty & Rewards: Deep Dive
This is where the philosophical difference between the two platforms becomes most apparent. Smile.io has spent years refining its loyalty engine, and it shows in the details.
With Smile.io, merchants can configure nuanced earning rules — for example, awarding bonus points for specific product collections, setting points expiration schedules, or creating time-limited bonus campaigns. The VIP tier system supports milestones based on points earned, amount spent, or number of purchases, each with distinct perk sets. For brands that see their loyalty program as a core brand asset, this granularity matters.
Growave’s loyalty module covers the fundamentals well: points for purchases and actions, discount-based redemptions, and a referral system. It is a strong, capable loyalty tool that will serve the majority of small to mid-size Shopify merchants perfectly. However, brands with complex loyalty strategies or those planning enterprise-scale programs may find they outgrow Growave’s loyalty features sooner.
Reviews & Social Proof: Deep Dive
This is Growave’s clear advantage. Smile.io simply does not include product reviews, so merchants must pair it with a separate app like Judge.me, Loox, or Stamped. That means managing an additional subscription, another dashboard, and potential compatibility concerns.
Growave’s native reviews module supports automated review request emails, photo and video reviews, review carousels, star ratings in Google search results (via structured data), and the ability to import existing reviews from other platforms. Having reviews and loyalty under one roof also creates interesting synergies — for example, awarding loyalty points for leaving a review, which encourages UGC while boosting program engagement.
Ease of Use
Both platforms are built specifically for Shopify and install directly from the Shopify App Store. Setup is generally straightforward for either app.
Smile.io’s interface is clean and focused. Because it only handles loyalty, the dashboard is uncluttered and easy to navigate. New merchants can typically launch a basic points program within 30 minutes.
Growave packs more features into its dashboard, which means a slightly steeper learning curve. However, the UI is well-organized with clear section separators for each module (loyalty, reviews, wishlists, etc.), and most merchants report being comfortable with the platform within a day or two.
Who Should Choose Smile.io?
- Loyalty-first brands: If your rewards program is a central part of your brand identity and customer retention strategy, Smile.io’s depth is worth the investment.
- Stores already using a reviews app: If you are happy with your current reviews solution (Judge.me, Loox, Yotpo, etc.) and just need a world-class loyalty add-on, Smile.io fits perfectly alongside those tools.
- Enterprise and high-volume merchants: Smile.io’s higher-tier plans offer API access, advanced analytics, and dedicated support for scaling operations.
- Brands that need advanced VIP tiers: Multi-tier programs with complex perk structures are a Smile.io strength.
Who Should Choose Growave?
- Budget-conscious merchants: If you are paying for 3–4 separate apps for loyalty, reviews, wishlists, and social login, Growave can consolidate those costs significantly.
- New Shopify stores: If you are building your tech stack from scratch, starting with one integrated app is simpler than assembling multiple point solutions.
- Stores that value reviews alongside loyalty: The synergy between awarding points for reviews and displaying that social proof on product pages creates a powerful growth loop.
- Visual and lifestyle brands: Growave’s UGC galleries and Instagram integration are especially valuable for fashion, beauty, home décor, and food brands.

There is no universal winner here — the right choice depends on your store’s priorities.
Choose Smile.io if loyalty is your primary growth lever and you want the most powerful, customizable rewards engine on Shopify. You will need to pair it with a separate reviews app, but the trade-off is unmatched loyalty depth and a mature integration ecosystem.
Choose Growave if you want a unified platform that handles loyalty, reviews, wishlists, and social proof in one install. It is the smarter pick for merchants who value simplicity, cost efficiency, and the synergies that come from having these features work together natively.
