Fassla is a shopping app for Android. You browse a catalog, add products to a cart, place an order, and pay without leaving the app. It runs on Flutter, so one codebase covers both Android and iOS.
The problem
A shop owner who wants to sell on phones faces a choice. Build one app for Android and a second for iOS, or pick a single platform and give up half the market. Both paths cost money and time. Fassla removes the first problem. One Flutter codebase produces native apps for both stores, and the catalog, cart, and checkout stay in step across devices.
What we built
- Phone sign-in with a one-time code. A shopper enters a mobile number and confirms an OTP before reaching the store.
- A product catalog you scroll and open for details.
- A cart that holds your items until checkout.
- Order placement and order history, so you can see what you bought.
- A payment gateway wired into checkout, so payment finishes inside the app.
- A Flutter build that targets Android and iOS from shared code.
How we worked
You worked with the engineers who wrote the code. No account manager sat between you and the build. Each week you got a version you could install and use, and your feedback reached the people who could act on it. The team that built Fassla maintains it.
The outcome
Fassla shipped to Google Play under AppCrew Technologies. The listing carries a 3+ content rating and reports no data collected and no data shared. AppCrew last updated the app on August 27, 2025. The iOS build has not reached the App Store yet.
