Custom mobile app development for iOS and Android
Apps for startups and small businesses: native Swift and Kotlin or one Flutter codebase, connected to your website, CRM and payments.
StackSwift, Kotlin and Flutter for apps; TypeScript, Go and Python for the back end.
What we build
iOS and Android app development
Native apps in Swift and Kotlin when you need the best performance and platform features, or one Flutter codebase when you want both platforms faster.
Apps for small business
Pre-orders, loyalty programs, booking and push notifications for customers, connected to the systems you already run.
MVPs for startups
A first version with the features that prove the idea, built so it can grow instead of being rewritten after the first investors or customers.
Back end and admin panel
The server side, API and admin panel the app needs, so your team can manage content, orders and users without a developer.
How we work
Estimate in one business day
Tell us what the app should do. We reply within one business day with a budget, timeline and our recommendation: native or Flutter.
Two-week stages with a demo
Every two weeks you install a working build on your phone and see progress for yourself.
Source code and docs are yours
Source code, store accounts and documentation stay with you.
Support after launch
We help with store publication, fix issues and keep the app up to date with new iOS and Android versions.

When a mobile app is too heavy, a messenger bot can do the job: one message sends an alarm to every trusted contact.

How much does it cost to develop a custom mobile app?
It depends on the number of screens, platforms, integrations and the back end. After a short brief we send a budget and timeline estimate within one business day.
How much does it cost to create an app for a small business?
Often less than people expect, because many small business apps reuse an existing website or CRM as the back end. Send us what you need, and we will tell you what can be reused.
Native or Flutter: which is better for iOS and Android?
Flutter gives you one codebase for both platforms and is usually the faster way to launch. Native Swift and Kotlin make sense when the app depends on heavy graphics, background work or the newest platform features.
What is custom mobile app development?
Building an app for your specific business process and customers, instead of configuring a template app builder. You get exactly the features you need and own the code.
How do I choose an app developer?
Ask to see working results, not only a portfolio; check that you will own the code and store accounts; and prefer a team that shows a working build every couple of weeks.
