Our approach to Android app development.

Android is not one device. It is a spread of screen sizes, chipsets, OS versions and manufacturer skins, and the phone your developer tests on is almost never the phone your customer is holding. An app that feels quick on a flagship can be unusable on a three-year-old mid-range handset, which in India is most of the market.

So we pick the test devices from your analytics, not from a wishlist. Cold start, scroll performance and memory are measured on the slowest device you have agreed to support, and that number goes in the spec rather than being discovered after launch.

The other half is Play policy. Target API level deadlines, the Data safety form, background execution limits and permission declarations all move, and each one can pull an app from the store if it is left until submission week. We handle those during the build.

What we settle before writing Kotlin
Minimum SDK, chosen from your analytics

Scope cut, devices chosen.

Interviews, a competitive read and one hard prioritisation session. Your analytics decide the minimum SDK and the slowest device we commit to, and Kotlin and React Native are both scoped and costed.

Through Play review, cleanly.

Store listing, screenshots at every required size, the Data safety form and the permission declarations that stop an avoidable rejection. We submit and we answer review.

What we build on Android.

Phone, tablet and large-screen work, described honestly. The published examples are in the portfolio.

Android work, end to end.

Consumer apps, internal tools, and the backends underneath them.

  • Native Kotlin and Jetpack Compose apps
  • Tablet, foldable and large-screen builds
  • React Native with native Android modules
  • APIs, integrations and data pipelines

Much of our product work sits under an NDA. Everything in the portfolio was built by the same engineers and is live right now, go and prod it.

Why teams pick us for Android.

What clients say after comparing us with larger app agencies.

01

We test on the phones people own

Test devices come from your analytics. A mid-range handset that is three years old is the real target, not the flagship the developer happens to carry.

Realdevices, not emulators
02

We design the first session

Time to first value is a spec item with a number against it. That is where installs are lost, long before anyone finds a bug.

Play policy is part of the build

Target API level, the Data safety form and permission declarations are settled early. Left late, any of them can pull a live app from the store.

Kotlin is not always right. We scope and cost both routes, and a third of the apps we ship turn out not to be native at all.

What Android app development
costs, and what shapes it.

What an Android app costs depends on its scope and on how many devices it has to behave on, not on a price list. Every engagement is scoped after a free consultation, and the written proposal carries the number.

  • One defined v1, phones only
  • Kotlin or React Native, costed both ways
  • Play submission handled by us
  • Analytics wired before launch

What do Android app development services cost in India?

There is no price list, because the number is set by scope rather than by platform. A single-purpose Android MVP and a native app with offline sync, background location and a backend behind it differ by an order of magnitude. We scope every engagement after a free consultation and put the figure in a written proposal, along with what would move it.

How long does it take to build an Android app?

Twelve to sixteen weeks is typical for a native Kotlin build, and ten to fourteen for React Native. Your team installs the first internal-track build in week five. Play review itself is usually three to seven days, which is faster than the App Store.

Which Android versions and devices will you support?

We set the minimum SDK from your own analytics rather than a default, and we name one slowest device that performance is measured against every sprint. Supporting one more version back costs testing time and constrains which APIs we can use, so it is worth deciding on data.

Should we build native Kotlin or use React Native?

It depends on what the app asks of the phone. Camera work, background location, offline sync, on-device processing and heavy animation point to native Kotlin. A product that is mostly screens, forms and data, and that needs iOS too, is usually better served by one React Native codebase with Kotlin written only where the hardware demands it. We scope and cost both before you decide.

Why does my app feel slow on cheaper phones?

Almost always because it was built and tested on a flagship. Cold start, scroll performance and memory behave completely differently on a three-year-old mid-range handset, which in India is most of the market. We pick that device up front and measure against it every sprint rather than discovering the problem in store reviews.

Who owns the code and the Play Console account?

You do, both, from the first commit. The app is published under your organisation's Play Console account rather than ours, and the repository is yours. If you leave us, the listing, the reviews and the install base stay exactly where they are.

Do you also publish to other Android stores?

We can. Most clients need Google Play alone, but if your market includes regions or devices where another store matters, we will say so during scoping rather than after. It changes the build less than people expect and the release process more.

What happens after the app is live?

Fourteen days of cover is included: ANR and crash triage in Android vitals, responses to store reviews, and the first read on where new users drop out. A retainer after that is optional and plenty of clients do not take one. If you do, it is the same engineers.

Where are you based, and can you work with us outside Kolkata?

Our studio is on Chowringhee Road, Park Street, and Kolkata is our only office. We build Android apps for clients across India, including Mumbai, Delhi NCR, Bangalore, Hyderabad, Chennai, Pune and Ahmedabad.

Do you work with clients outside India?

Yes. We have delivered in 23 countries across five continents, and we commit to four guaranteed overlap hours with US Eastern (18:30–22:30 IST), with a full overlap for the UK and Europe. The names are in the contract.
