A loyalty app on both stores in three weeks
A React Native app with in-store scanning, points, push campaigns and a Shopify-connected backend, built as an MVP then extended.

The challenge
A paper loyalty card that customers lost, and no way to contact anyone who used it.
Two previous quotes priced iOS and Android as separate builds, doubling the budget.
Stock and pricing lived in Shopify, which the loyalty scheme knew nothing about.
What we did
- 1
Cut the wish list to one job for version one: scan in store, collect points, redeem.
- 2
Built a single React Native codebase for both stores, with Expo for over-the-air updates.
- 3
Connected the Shopify catalogue so points and offers always reflect live pricing.
- 4
Shipped to TestFlight in week two, gathered feedback from 40 regulars, then released.
The outcome
Live on both stores three weeks after kickoff, inside the original fixed price.
Push campaigns replace printed vouchers, at no per-message cost.
A contactable customer list, where the paper card scheme gave none.
