Kotlin App Development Company

Native Android Development Without the Boilerplate

Kotlin has been Google's preferred language for Android since 2019, and for good reason: it's concise, null-safe, and pleasant to work in. Our Android engineers at GTS Infosoft build with Jetpack Compose for UI, coroutines for async work, and the rest of the modern Jetpack stack — Room, Hilt, WorkManager. Less boilerplate means fewer bugs and faster releases, and Android has plenty of both to save you from.

We're an ISO 9001:2015 certified software studio in India with 16 years behind us and 250+ apps shipped. Android is messy — thousands of device models, wildly different screen sizes, OEM battery restrictions — and we've learned its sharp edges the hard way so your users don't have to. Dedicated Kotlin teams start around USD 20/hr, serving clients in India, the USA and Australia.

Frequently Asked Questions

How much does Kotlin Android app development cost?

A straightforward MVP usually falls between USD 8,000 and 25,000 at our India-based rates, which start around USD 20/hr. What moves the number most: screen count, offline requirements, third-party integrations, and how many device types you need tested. We'll break it all down in a free, itemized quote.

Is Jetpack Compose production-ready?

Very much so. Compose has been stable since 2021 and it's what Google builds its own apps with now. We use it for all new projects. For older codebases we migrate screen by screen — Compose and XML views interoperate fine, so there's no risky big-bang rewrite.

Should we build native Kotlin or go cross-platform with Flutter?

Native Kotlin wins when you're Android-first, need deep platform features, or care about performance on low-end devices — a big deal in the Indian market. If iOS and Android must launch together on a lean budget, Flutter often makes more sense. We build both, so our advice isn't biased toward either.

Can you take over an existing Android app built by another team?

Yes, and we do it often. We start with a code audit — architecture, crash rates, dependency health — then give you a frank report before committing to anything. Some codebases need refactoring, some just need steady hands. We'll tell you which yours is.

How long does an Android app take to build?

Around 6-10 weeks for a focused MVP, 3-6 months for something feature-rich. Play Store review is quicker than Apple's, usually a day or two. We run two-week sprints with demos, so you watch the app take shape rather than waiting for a big reveal.
