I’m building the first release of a “store passport” mobile experience that lets shoppers check in at participating locations and accumulate rewards, while giving each merchant a simple way to publish store details and monitor visitor activity. Scope of the MVP • Native releases for both iOS and Android (a shared code-base such as Flutter or React Native is fine). • User side: seamless location-based check-ins, a running tally of stamps/points, and a map or list of nearby venues. When a user taps “Check In” and is physically at the store, the reward balance must increment immediately and update in their history. • Merchant side: a lightweight portal (mobile or web) where a business can create an account, enter store information, upload imagery, and view high-level statistics on visits and unique users. • Central back-end to hold user accounts, merchant accounts, reward balances, and check-in logs; it should be cloud-ready so we can scale without re-architecting later. Acceptance criteria 1. TestFlight and Google Play internal builds delivered, installable on current OS versions. 2. A fresh user can register, find a nearby demo store, check in, and see a reward added. 3. A merchant can sign up via the portal, add/edit store info, and view a dashboard chart of visits. 4. All source code, environment instructions, and API documentation handed over in a private repo. Please outline your preferred stack, any similar apps you have shipped, and the timeline you need to get this MVP live.
