iOS
Native iPhone and iPad apps in Swift, built to Apple's Human Interface Guidelines and App Store review standards.
iOS and Android studio
We design and build mobile apps.
S.Z. ISTAY LIMITED is a mobile software studio based in Cyprus. We take products from first idea to the App Store and Google Play — design, engineering, and release under one roof.
What we do
Native apps, built properly for each platform.
No cross-platform shortcuts that age badly — real Swift and Kotlin, tuned to the guidelines each store actually reviews against.
Android
Native Android apps in Kotlin, from phones to tablets and foldables, ready for Google Play.
End to end
Product design, development, release, and iteration — one team accountable from concept to launch.
How we work
A short path from idea to store.
01 — Design
Shape the idea
We turn the concept into flows and interfaces people understand instantly, then prototype before a line of production code.
02 — Build
Engineer it well
Clean, native code with each platform's own tools — maintainable, testable, and fast on real devices.
03 — Ship
Release and iterate
Store submission, review, and the steady updates that keep an app healthy long after launch day.
Two platforms, one team
From iPhone to Android, prototype to production.
We work across the whole surface of a mobile product — native iOS and Android, the services behind them, and the release pipeline that ships them to real devices.
