React NativeExpoNext.js
Lom, Bulgaria
Mobile app development — Lom
iOS and Android apps from a single codebase, with a backend, payments and publishing on the App Store and Google Play.
We build mobile apps with React Native and Expo — one codebase for iPhone and Android. Our FIX, Heal Fit, Avanta and ZapaziChas apps are published on the App Store. Alongside the app, we build the server and admin panel it runs on.
We work from Sofia with clients across the country — remotely, and on-site when the project requires it.

Questions and answers
How much does it cost?
€200–€15,000. The exact price is stated in the written quote.
How long does it take?
It depends on the scope—we’ll include it in the quote. For comparison, here are examples from our portfolio: FIX Bulgaria — 6 months, Avanta — 4 months, Offroad Buddies — 5 months.
Who owns the app?
Yours. The code and data are handed over with the project, and the app can be published from your App Store and Google Play accounts.
What happens after launch?
If you wish, we can maintain the project for €100–€350 per month. We specify what maintenance includes in the quote.
Can you connect the app to payments, SMS and maps?
Yes. FIX, Avanta and ZapaziChas accept payments through Stripe, ZapaziChas sends SMS reminders, and Offroad Buddies records routes on MapBox maps.
Do I need a backend too?
Almost always — that is where the users, data and payments are. We build it together with the app or connect the app to your existing system.
Can we start with an iPhone-only app?
Yes. With React Native, the code is shared, so the Android app does not have to be built from scratch.
