Key takeaways
  • Smile rates 4.9★ across 4,172 reviews vs Stamped's 4.7★ across 3,404 reviews.
  • Stamped's $299/mo Loyalty plan is billed separately from Reviews, which starts at $23/mo — the two aren't bundled into a single price.
  • Smile's $199 top tier costs less than Stamped's $299/mo Loyalty-only plan, and Smile adds VIP tiers, POS support, and native Klaviyo sync.
  • Smile has zero native review functionality; it only earns points for reviews via separate integrated apps.
  • Stamped's edge is bundling: native review collection, Google Shopping syndication, and loyalty in one dashboard.

Smile: Loyalty Program Rewards is the stronger pick for most Shopify merchants shopping for a dedicated loyalty program — it holds a 4.9-star rating across 4,172 reviews versus Stamped Reviews & Loyalty's 4.7 stars across 3,404 reviews, and its loyalty tooling (VIP tiers, referrals, native Klaviyo sync) is deeper because loyalty is Smile's entire product. The exception: if you specifically want reviews and loyalty running from one dashboard to cut your app count, Stamped is the honest choice, even though its loyalty module is flatter and, billed alongside Reviews, costs more than Smile's top tier.

Who this is for: Shopify merchants comparing a purpose-built loyalty engine (Smile) against a reviews platform with loyalty bundled in (Stamped) — typically stores already running a separate reviews app that want to add points/VIP/referrals, or stores trying to consolidate reviews and loyalty into fewer app-store subscriptions.

01 Smile vs Stamped at a Glance

Smile leads on both rating and review volume, and the two apps aren't actually competing on the same axis: Smile is loyalty-only, while Stamped's "loyalty" is a module layered onto a reviews product. That architecture difference explains most of the gaps below.

Native review collectionNo — integrates with Stamped, Yotpo, OkendoYes, plus Google Shopping syndication
Native Klaviyo integrationYes — built into Klaviyo's Customer HubNot natively

02 Pricing Breakdown: Free Plans, Paid Tiers, and Where Costs Jump

Smile offers a free plan plus three paid tiers: Essential at $15/mo, Standard at $79/mo, and Growth at $199/mo.

Stamped prices Reviews and Loyalty as two separate products. Reviews starts at $23/mo, while Loyalty is a flat $299/mo plan — there's no cheaper loyalty entry point. A merchant who wants both products from Stamped pays for Reviews and Loyalty as separate subscriptions, on top of each other.

The practical result: Smile's $199 top tier is priced well below Stamped's $299/mo Loyalty plan on its own, before even accounting for the separate cost of Stamped's Reviews product.

03 Loyalty Program Features Compared

Both apps cover the loyalty basics — points, VIP tiers, referrals, discount and free-shipping rewards, and a dedicated rewards landing page — so on paper they look close. In practice, Smile goes deeper because loyalty is the whole product, not a module.

  • Redemption breadth — Smile offers a wide range of earning and redemption methods, versus Stamped's more standard points/VIP/referral set.
  • Subscription and bonus rewards — Smile offers bonus events and subscription-linked rewards; Stamped's Loyalty plan doesn't call out an equivalent.
  • Native Klaviyo sync — Smile is built directly into Klaviyo's Customer Hub, syncing point balances and VIP tier into pre-built email flows triggered by referrals, redemptions, and birthdays. Stamped has no equivalent native integration.
  • POS and Checkout — Smile supports Shopify POS and Shopify Checkout natively, so loyalty works in-store and at checkout, not just on-site.
  • Redemption UX — a real weak spot for Smile: reviewers report a confusing discount-code redemption flow, especially on POS.

Stamped's loyalty module is solid and covers the fundamentals well, but it's gated behind one $299/mo plan with no lower entry point and no equivalent of Smile's Klaviyo depth or bonus-event flexibility.

04 Reviews & UGC Features: Stamped's Built-In Edge

This is where Stamped genuinely wins, because Smile isn't in this category at all. Smile has zero native review-collection, moderation, or display functionality — it only awards points for reviews left in a separate, integrated app, and integrations aren't even available on Smile's free plan. So a merchant who wants "reviews plus loyalty in one dashboard" cannot get that from Smile at any price; they'd need Smile plus a review app, which defeats the app-count-reduction goal entirely.

Stamped, by contrast, is a full review-collection platform: photo/video review requests, on-site display widgets, and Google Shopping syndication, giving product listings rich-snippet star ratings that Smile has no path to since it doesn't touch reviews. If review collection and search-visible ratings matter to you, Stamped's bundle is the only one of the two that covers it.

05 Setup, Shopify Theme Integration, and Support

Smile's support is the standout strength in its reviews — described repeatedly as responsive, knowledgeable, and proactive about loyalty strategy. Its main friction points are pricing structure (some reviewers feel the jump to the $199 Growth tier is steep), order-limit lockouts on lower plans, and no easy bulk-import of an existing customer list into the program.

Stamped earns praise for being clean and reliable with responsive, professional support from long-term users. Theme integration is generally easy on standard Online Store 2.0 themes, but the auto-install script doesn't cover every theme, so some custom or legacy setups need manual work.

06 Final Verdict: Which Should You Install?

Smile: Loyalty Program Rewards is the winner for merchants who want the strongest dedicated loyalty program: it rates higher (4.9★ vs 4.7★), has more reviews (4,172 vs 3,404), offers a genuinely free entry point, and its top $199/mo tier costs less than Stamped's $299/mo Loyalty-only plan. Smile overall also offers VIP tiers, POS support, and native Klaviyo integration that Stamped can't match. Its main honest weaknesses are a confusing redemption UX and a jump to $199/mo for its top plan.

Stamped Reviews & Loyalty is the right call only for one specific segment: stores that want reviews and loyalty managed from a single app to reduce their app-store footprint, and are willing to pay for both products separately (Reviews starting at $23/mo plus Loyalty at $299/mo) and accept a flatter, single-tier loyalty toolset in exchange for built-in review collection and Google Shopping syndication. For loyalty depth alone, Smile is the better buy at nearly every store size.
