Mobile apps
Native iOS and Android apps
When an app must be as smooth as possible and use everything the phone offers, we build it natively, separately for each platform.
What we can do for you
iOS in Swift
Apps for iPhone and iPad that follow Apple guidelines.
Android in Kotlin
Apps for Android phones and tablets that follow Material Design guidelines.
Device features
Camera, location, Bluetooth, biometrics, notifications and offline mode.
In-app payments
Subscriptions and purchases compliant with store rules.
About this service
Mobile app development covers UX/UI design, an iOS and Android app, backend and API, push notifications and publishing in the App Store and Google Play. Depending on the project we choose native apps in Swift and Kotlin or a cross-platform solution in React Native.
We treat a mobile app as part of a larger system: we connect it to the server, admin panel and other company services, and after launch we provide updates and support.
Why Cormo
High performance
Smooth animations and fast operation even on complex screens.
Full system access
New platform features available right after release.
Store compliance
Apps prepared for App Store and Google Play requirements.

Experience you can rely on
We build mobile apps and prepare them for publication in the App Store and Google Play. We work in React Native and native technologies, and build the app together with its backend and admin panel.
How we work
- 01
Meeting
We learn the business goal, the users and the project constraints.
- 02
Estimate
We settle the scope, a first estimate and a schedule.
- 03
Delivery
We design, build and test in short iterations.
- 04
Support
We deploy, monitor and evolve the solution after launch.

React Native apps
One codebase for iOS and Android. You reach users on both platforms faster, and maintenance is usually simpler and cheaper.
Frequently asked questions
When should I choose native iOS and Android apps over a cross-platform solution?
Native makes sense when the app must be as smooth as possible or relies heavily on phone features such as the camera, Bluetooth, biometrics, location or offline mode. It also gives full access to new system capabilities right after they ship. The cost is two separate projects, in Swift and Kotlin, which usually means more work than React Native. For simpler apps we often recommend cross-platform.
How does building a native app work and how long does it take?
After a workshop and UX/UI design, we build the iOS app in Swift and SwiftUI and the Android app in Kotlin with Jetpack Compose. Both can progress in parallel, but each has its own code, tests and release schedule. We work iteratively, and you receive builds through TestFlight and Google Play internal testing. Timing depends on the number of features and device integrations, and we give a date after the analysis.
Why does a native app cost more and what drives the estimate?
A native app means two separate codebases that must be written, tested and maintained, so the scope of work is wider than with a single codebase. Price is also shaped by the number of screens, hardware features (Bluetooth, camera, biometrics), offline mode, backend and integrations. We split the estimate into stages, and with a limited budget we can start with one platform and add the other later.
How do you test across devices and protect data stored on the phone?
We test on various models and OS versions, because Android in particular runs on very diverse hardware. Sensitive data goes into secure system storage (Keychain, Keystore), API communication is encrypted, and biometrics use system mechanisms. Our security processes are aligned with ISO/IEC 27001. No team can test every device, so after release we monitor crash and error reports.
Will I need to update a native app after every new iOS and Android version?
Not after every one, but regularly. Apple and Google change requirements each year, deprecate old interfaces and raise minimum target versions, and stores may require updates. That is why ongoing support is worth planning: fixes, adaptation to new system versions and feature development. The code and documentation are yours, so you can run this on your own or with us.
