Mobile App
Development
From an MVP in a couple of weeks to a product with hundreds of thousands of installs. We handle store publishing.
Who this is for
If even one of these sounds like you, let's talk.
- You have an idea, but no sense of whether it'll work or what it costs
- Customers keep asking for an app, and all you have is a website
- Your last contractor delivered an app that keeps crashing
- The App Store keeps rejecting your app
- You need to test a hypothesis on real users, fast
What's included
Everything under one roof.
- User flows and a prototype worked out before development starts
- Design built to iOS and Android guidelines
- Cross-platform with Flutter when speed matters
- Native development when performance matters
- Push notifications and behavior analytics
- In-app payments and subscriptions
- Publishing to the App Store and Google Play
- Post-launch support and updates for new OS versions
Our process
From hypothesis to app store
App store pitfalls
Review is a real stage, not a formality.
- Apple rejects apps for non-obvious things: empty states, a missing test account, wording in the description
- An app that's just a wrapper around a website almost never gets approved
- Selling digital goods outside the store's payment system is a straight ban
- You need a privacy policy and a description of what data you collect
- The first submission takes longer than updates do — budget a few days
- Developer accounts are registered in your name — the app has to stay yours
What decides an app's fate
A download isn't the same as a user.
Sometimes the honest answer is that you don't need an app. If the goal is selling and answering questions, a mobile-friendly website or a Telegram bot solves it cheaper and faster. We'll tell you that before we take your money.
- First launch: people need to get the value within a minute, or they delete it
- Speed: people forgive a slow website, but not a slow app
- Push notifications need to be worth sending — annoying ones get the app deleted, not muted
- Works on bad connections: in the subway or an elevator, the app shouldn't just go blank
- Updates for new iOS and Android versions — otherwise it stops launching within a year

Questions
Frequently asked questions
Flutter or native development?
Flutter — when you need to launch on both platforms fast and the budget is tight: one codebase, half the time. Native — when you need heavy graphics, complex camera work, or maximum smoothness. We decide on the first call, based on the task, not on what's trendy.
How much does a mobile app cost?
The cost is calculated after we work out the prototype: the scope and price are locked into the contract and don't change after that. To get a sense of the numbers before we talk, we broke down what goes into the price of a mobile app: MVP or full product, cross-platform or native, backend, and store publishing.
Do you publish the app to the stores?
Yes, we handle publishing ourselves: developer accounts, preparing materials, getting through review. If Apple rejects a build, we fix it and resubmit at no extra charge.
What about support after launch?
iOS and Android update twice a year, and an app without support eventually breaks. So we offer a package: updates for new OS versions, crash monitoring, and hours for fixes.
Where do I start if I have an idea but a limited budget?
With an MVP. Ship one core feature, put it in front of real users, and see if they come back. Plans almost always change after that — and it's a good thing you haven't spent the money on the full product yet.
iOS and Android at once, or one at a time?
If the budget is tight, we go one at a time. In Belarus, Android has the bigger installed base, so that's usually the platform we start with. With cross-platform development the cost gap between one platform and two is small, so it often makes sense to launch both together.
Does the app need a server?
Almost always. Anything involving accounts, orders, or syncing across devices needs a backend — and that's roughly half the work a user never sees. The exception is simple offline utilities.
What if the App Store rejects the app?
That's a normal part of the process, not a disaster: Apple sends a reason, we fix it, and resubmit. Most rejections are predictable, and we try to head them off before submitting — but nobody can guarantee approval on the first try.
Who owns the app and the accounts?
You do. Developer accounts are registered under your company, and you get the source code. This matters: an app tied to a contractor's account is a hostage.
