FAQ

Questions about Android development.

How much does an Android app cost?

Most Android MVPs cost $25,000–$60,000. Apps for POS or custom hardware may need extra device testing.

How do you handle so many devices?

Adaptive layouts, a real device lab and analytics on which devices your users actually have.

Can you build for POS terminals?

Yes — we built the Clover POS app for MyMeest and work with scanners and rugged devices.

Native or cross-platform?

Native Kotlin is best for hardware and Android-first products; Flutter or React Native if you need iOS on the same budget.

Do you publish to Google Play?

Yes, including store listing, policy checks and staged rollouts.

What language is used for Android app development?

Modern Android apps are built in Kotlin with Jetpack Compose for the interface. Perpetio builds native Kotlin apps and tests them on real devices before every Google Play release.

How long does it take to build an Android app?

A focused Android MVP usually takes 8–12 weeks from discovery to Google Play release. Larger apps are delivered in phases, with a test build every two weeks.
