[CASE STUDY] How SMFit’s App Paid for Itself in Its First Month with SimiCart
SMFit, a Bulgarian sportswear and fitness accessories brand, partnered with SimiCart to bring its Shopify store to mobile — and saw the investment pay off almost immediately.

Why go mobile
When asked why SMFit wanted to build a mobile app, the team pointed to two priorities:
- Enhance customer engagement & loyalty
- Strengthen brand identity
Solutions
SimiCart plan: Pro
Keeping the app and online store consistent with linked product variants
SMFit uses connected/linked products on their online store, where related items are grouped as variants of one another. SimiCart’s team helped realize this in the SMFit mobile app, so linked products display consistently as variants rather than appearing as separate, disconnected listings — keeping the shopping experience aligned between the app and the web store.
Multi-language push notifications
SMFit sells to customers across two languages, so a single-language push notification strategy wasn’t going to work. SimiCart’s team added translation capability for push notifications — covering both one-time marketing campaigns and automated order-update notifications — so customers receive messages in their own language rather than a generic broadcast.
Results
SMFit launched its app in September 2025 and saw fast, tangible traction:
- The app paid for itself within the first month of launch.
- 2,110 tracked installs
- 2.1K new users and 1.2K returning users — a strong returning-user rate for a newly launched app
- 18m 03s average engagement time per active user
The app is live on both major app stores:
