Mobile applications for iOS and Android
Native and cross-platform apps — from prototype to publication on the App Store and Google Play.
- Timeline
- from 5 weeks
What it is for
A presence on the user's home screen, access to device capabilities the web does not have (push notifications, offline mode, camera, location, biometrics), and retention for audiences whose primary context is mobile. A separate case is internal apps for staff: warehouse, couriers, field service, sales representatives.
How we do it
We start by choosing the platform strategy: React Native gives one codebase and speed; native Swift and Kotlin give maximum performance and same-day access to new system APIs. We design to the Human Interface and Material guidelines, wire up push notifications, offline sync and payments, take the app through App Store and Google Play review, and set up release delivery.
A mobile app earns its cost where users come back regularly and need the device's capabilities. If the scenario is one-off, the honest recommendation is web or a Mini App — and we will say so before the contract, not after.

Stages
Stages
Platform strategy
We calculate which is cheaper in your case — one React Native codebase or two native apps. The answer depends on graphics requirements, background work and system API access.
Design definition
Flows, navigation, network and error states. Offline gets special attention — it is where most field-staff apps break.
Visual design
Layouts for both platforms accounting for differences in navigation, gestures and typography. Dark theme and screen sizes from compact phones to tablets.
Build
One-week sprints with a TestFlight and internal-track Play build after each. You test the app on your own phone from week two.
Publication
Store metadata and screenshots, review submission, automated release delivery. Developer accounts are registered to the client's company.
Support
Crash reporting, metric monitoring, regular releases and timely adaptation to new iOS and Android versions.
FAQ
React Native or native?
React Native pays off when logic matters more than graphics — accounts, catalogues, orders, internal tools. Native is needed where complex animation, heavy camera work or system-level background tasks are critical. We cost out both and show the difference in money and time.
Mobile app or Telegram Mini App?
The honest answer depends on the scenario. Rare, short sessions favour a Mini App, because there is no install barrier. Push notifications, offline and a home-screen presence require an app. Sometimes the right answer is both — and then they share a backend.
Who owns the store accounts?
The client. App Store Connect and Google Play Console accounts are registered to your company and we are added as developers. This matters: an app published from a contractor's account is a hostage.
What if review rejects the app?
The common rejection reasons are known in advance — insufficient justification for permissions, no account deletion, payments routed around in-app purchase. We design for them, and handling review plus fixing their remarks is included in the project at no extra charge.
