Mobile app development for iOS and Android
We do mobile app development for businesses and their customers — investor cabinets, booking and service apps, companion apps for web platforms — and ship the apps to the App Store and Google Play. One team handles the app, the backend behind it and the admin that runs it, under one contract with a fixed price.
Most of our apps are written in React Native with Expo: one codebase for iOS and Android, native speed where it matters, and quick over-the-air fixes that don’t wait for a store review. When a feature needs native code — background location, Bluetooth, heavy media — we add native modules for that part.
An app is rarely alone. Usually it shares a backend with a web platform for staff, so an order placed on a phone is the same record the manager sees in the browser.

Mobile app development
What we build
Customer apps
Sign-up, profiles, catalogues, bookings, payments and push notifications — the app your clients keep on the home screen.
Companion apps for platforms
The focused mobile side of a bigger web system: an investor’s portfolio, an inspector’s job, a courier’s route.
Staff and field apps
Approvals, checklists with photos, daily tasks and forms that survive a bad connection, for people who aren’t at a desk.
Telegram Mini Apps
When your audience already lives in Telegram, a Mini App reaches it without an install.
Backend and admin
The API, database, notifications and admin panel the app needs, built by the same team.
Store release
Builds, store review requirements and the first release to the App Store and Google Play.
How it works
From a brief to an accepted product
The same five steps for every project, whatever we build. You always know what is agreed, what is paid and what is done.
Estimate
Describe the product in your own words, add a link or a file. In about 15 seconds you see the modules, the hours, the timeline and a price.
Team review
Our team reads the brief and the estimate, asks about anything unclear in your cabinet or on a call, and confirms the scope and the price. Nothing starts before that.
Contract
You sign a contract online: a fixed price, the scope split into modules, and a payment schedule — in full or by stages.
Milestones
We build module by module. QA checks each one before it reaches you, and the cabinet shows the work as it moves.
Acceptance
You have 7 days to review each module: accept it or send it back with a list of fixes. Your money stays in the project reserve until you accept.
Three formats
Choose how we build it
The format decides who writes the code and how much engineering review goes into it — and with that, the price and the pace.
- AI / build
AI Build
Fastest path · prototypes & internal tools
AI generates the structure and most of the implementation. Engineers review integrations and the release. The lowest cost, for prototypes, internal tools and MVPs that test an idea.
- AI / engOur pick here
AI + DEV
Recommended for most MVPs
AI builds the scaffolding and the obvious parts. Engineers own the architecture, critical logic, integrations and full QA. Balanced pace and review, for customer-facing MVPs and B2B products.
- full / eng
DEV
Maximum quality & control
Senior developers own architecture and implementation end to end. AI is an internal tool for speed, never the final author. For production systems and regulated domains.
A consumer app with payments or personal data is an AI + DEV or DEV job: store review, devices and edge cases need engineers. AI Build works for an internal app or a first version you test with a small group.

FAQ
Questions we get asked
How much does it cost to develop a mobile app?
It depends on the screens, the roles and the logic on the server, so we price by modules. The estimate gives a first price in about 15 seconds; one codebase for iOS and Android usually costs noticeably less than two native apps. The price in the contract is fixed.
React Native or native development?
For most business apps, React Native with Expo: one codebase, one team, faster releases. Native is worth it for heavy graphics, deep hardware work, or when a new platform feature isn’t supported in React Native yet. We tell you which one your app needs at the team review.
Will you publish the app to the App Store and Google Play?
Yes. We prepare the builds, follow the store review requirements and publish the app under your developer account, so it belongs to you from the first release.
Does my app need a backend?
Almost always: accounts, data, payments and notifications live on a server. We build the backend and an admin panel together with the app; if you already have an API, we connect to it.
How long does it take to build an app?
A focused first version usually takes weeks, not months; the estimate shows a timeline for your scope and the contract fixes it. Store review adds a few days to the first release.
What happens after release?
Accepted modules come with a warranty: reproducible defects in our code reported within 30 days are fixed free of charge. New features start with a new estimate in the same cabinet, so the app keeps growing on the same terms.
