Mobile app development services

We build one app that runs on iPhone and Android, in React Native or Flutter, and take it through App Store and Google Play review. A first version typically costs $5,000-15,000 and takes 2-4 weeks, plus store review. HealthyNikah, Traza, LEV and YOU(th) each run as one app on both stores. Clients rate us 4.8 out of 5 on Clutch from 70 reviews.

What we build into mobile apps

Features we built into React Native and Flutter apps, and the apps that use them.

Subscriptions and in-app purchases

HealthyNikah runs its membership and match credits on RevenueCat with Apple and Google in-app purchases, and Stripe for payments outside the stores. YOU(th) sells subscriptions in both stores.

Bookings, deposits and chat

In Traza, tattoo artists answer requests, plan sessions, take deposits and message clients from their phone. A push notification arrives with every new request.

Live maps

LEV shows dog owners on a live map as they walk and pins dog-friendly places nearby. Filters and clustering keep hundreds of pins readable.

Camera and voice checks

YOU(th) runs a health check from a face video, a voice sample and an eye photo. It takes under 2 minutes and needs only the phone.

Matching and chat translation

Kosmo matches people by zodiac sign and translates their chats into other languages in real time.

Live video

Spartacus matches fighters and streams their fights live on the web and on phones. The app has 100,000+ downloads on Google Play.

React Native, Flutter or native Swift

React Native and Flutter both give you one app for both stores from one codebase. 9 of our case studies use React Native and 7 use Flutter. If you only need iPhone, native Swift can fit better.

How we build a mobile app

You see a demo every week and can change priorities. We plan for App Store and Google Play review from the first screen.

StepWhat we doWhat you get
Scope and designWe agree on your users, the main task and what waits for later. Then we design the main screens.A written scope and screens you can click through
BuildWe build one app in React Native or Flutter. Sign-up, payments and the admin panel come from ready-made modules.An app you can test on an iPhone and an Android phone
TestingWe test each feature on both platforms and fix what breaks before your users see it.A build ready for review
Store reviewWe send the app to review early, because Apple review can take one to two weeks. Traza went to review early and was approved on both stores.Your app on the App Store and Google Play
After launchWe fix what users report and plan the next release around what they do.A plan for the next release

If you already have a team and a backlog, add our React Native or Flutter developers to it at $39-55 an hour. They work in your process and report to your lead.

Join your team

Traza had web developers but no mobile ones. Two of our React Native developers joined, and the artist app reached both stores.

Take over an app

If another team left you with half-built code, we review it first, then keep, fix or rebuild it.
