Customer loyalty programmes have become a standard feature of successful ecommerce brands. A well-designed loyalty programme increases repeat purchase rates, raises average order values, and creates an emotional connection between customers and your brand. Smile.io and LoyaltyLion are the two most popular loyalty platforms for Shopify, and each brings genuine strengths to the table.
Smile.io powers loyalty programmes for over 100,000 brands and is known for its accessibility, generous free plan, and straightforward setup. LoyaltyLion serves thousands of brands with a deeper feature set, more customisation options, and stronger analytics — at a premium price point. The choice between them depends on your brand's size, budget, and loyalty programme ambitions.
Having set up both platforms for Shopify stores, I can offer a practical comparison based on real-world implementation experience rather than marketing claims.
Platform overview
Smile.io is the most widely used loyalty platform for Shopify. It supports points programmes, VIP tiers, and referral programmes with a clean, easy-to-use interface. Smile.io's free plan supports up to 200 monthly orders, making it accessible to small brands. The platform prioritises simplicity — most stores can have a basic loyalty programme running within an hour of installation.
LoyaltyLion is a UK-based loyalty platform founded in 2012. It provides deeper customisation, more sophisticated loyalty mechanics, and stronger analytics. LoyaltyLion is designed for growing and established brands that want a loyalty programme that goes beyond basic points collection. Pricing starts higher than Smile.io, reflecting its more advanced capabilities.
Points programmes
Both platforms support points-based loyalty programmes where customers earn points for purchases, account creation, social follows, birthdays, and other actions. Points can be redeemed for discounts, free products, or free shipping.
Smile.io's points system is straightforward and covers most common earning and redemption scenarios. The setup is guided and intuitive, with pre-configured earning rules that can be customised. LoyaltyLion's points system is more flexible, supporting custom earning rules, points expiry, points for specific product purchases, and more granular control over point values and redemption thresholds.

VIP tiers
Both platforms support VIP tier programmes. Smile.io offers up to three VIP tiers on paid plans, with customisable tier names, icons, entry thresholds, and perks. The tier system is visual and easy for customers to understand. LoyaltyLion supports unlimited VIP tiers with more flexible tier rules — tiers can be based on points earned, amount spent, number of orders, or custom criteria. The tier system integrates with other platform features for more sophisticated loyalty mechanics.
Referral programmes
Both platforms support referral programmes. Smile.io includes referrals from its free plan, allowing both the referrer and referee to earn rewards. LoyaltyLion's referral features are available on paid plans and offer similar functionality with additional customisation options. Both track referral performance and provide analytics on programme effectiveness.
Pricing comparison
- Smile.io Free: up to 200 orders/month, basic points and referrals
- Smile.io Starter: $49/month — VIP tiers, branding customisation
- Smile.io Growth: $199/month — advanced features, integrations
- Smile.io Plus: $999/month — enterprise features, API access
- LoyaltyLion Classic: from approximately $199/month
- LoyaltyLion Advanced: from approximately $699/month
- LoyaltyLion Plus: custom pricing for enterprise
Smile.io is significantly more accessible for smaller brands. LoyaltyLion's higher entry point reflects its more advanced feature set. For a broader comparison, see our guide to the best Shopify loyalty apps.
Customisation and branding
Smile.io provides good visual customisation — colours, programme name, widget positioning, and email branding are all adjustable. The widget design is clean and looks professional on most stores. LoyaltyLion provides deeper customisation through CSS, custom components, and API-driven implementations. For brands wanting a fully bespoke loyalty experience integrated into their custom theme, LoyaltyLion's flexibility is an advantage.
Analytics and ROI tracking
Smile.io provides basic analytics — programme member count, points issued and redeemed, referral performance. The data is sufficient for understanding programme participation but limited for measuring ROI. LoyaltyLion provides significantly deeper analytics — revenue attribution, member versus non-member spending comparison, programme ROI, cohort analysis, and custom reports. For brands that need to justify loyalty programme investment with data, LoyaltyLion's analytics are substantially more useful. See our analytics guide for broader measurement strategies.
Integrations
Both platforms integrate with essential Shopify tools. Smile.io integrates with Klaviyo, Judge.me, Gorgias, and other popular apps. LoyaltyLion integrates with Klaviyo, Yotpo, Gorgias, ReCharge, and a broader set of tools. For Klaviyo email marketing, both platforms provide useful loyalty data for segmentation. LoyaltyLion's Klaviyo integration offers more granular event data.
On-site experience
Smile.io displays a loyalty widget (panel or embedded) that shows points balance, available rewards, and tier status. The widget is clean and well-designed. LoyaltyLion offers similar on-site widgets with more customisation options, including the ability to embed loyalty content throughout the store — on product pages, in the cart, and on dedicated loyalty landing pages.
Email marketing integration
Both platforms trigger loyalty-related events that can be used in email flows — points earned, tier upgrades, points expiry reminders, and referral invitations. LoyaltyLion passes more loyalty data to Klaviyo (points balance, tier, lifetime points), enabling more personalised email content. For effective email strategies, see our guide to essential Klaviyo flows.
Support and onboarding
Smile.io provides self-service onboarding, documentation, and email support across all plans. Higher-tier plans include dedicated support. LoyaltyLion provides dedicated account management and strategic support on higher plans, which is valuable for brands wanting guidance on loyalty programme strategy and optimisation.
