Phone, tablet, and Galaxy Watch
An Android app development agency that ships to the Play Store.
Time is money. We build Android apps that get approved and stay stable: phone, tablet, and Samsung Galaxy Watch. React Native is our first-choice stack for most apps, with Kotlin and Jetpack Compose for native Android where a product needs it. Audit-first, published pricing, founder-operator scale.

Android delivery outcome
Dead Xamarin app to production React Native on Android
A client's Android app ran on Xamarin, an ecosystem that had gone cold, and they could not hire for it. We took over a codebase untouched for 12+ months, reverse-engineered the feature set, and migrated it to production React Native in 9 months, shipping to the Play Store and teaching the internal team the toolchain so they could maintain it without us.

These are the situations that bring founders and product teams to an Android app development agency.
You need a native-quality Android app, not a wrapped website
Your product needs to feel right on Android: Material patterns, real navigation, notifications, and performance that holds up across the fragmented device landscape. We build apps that pass Play Store review and feel native, whether in React Native or in Kotlin and Jetpack Compose.
You want Kotlin and Jetpack Compose done properly
When a product leans on platform-specific Android capability, native is the right call, and modern native Android is Kotlin with Jetpack Compose. We build declarative Compose UIs, not legacy XML layouts dragged forward, with the architecture and testing to keep them maintainable.
You want one team for phone, tablet, and Galaxy Watch
Phone is the start, but the product story often includes tablet layouts and a Samsung Galaxy Watch companion. We build across the Android device family from one engagement, so the experience stays coherent instead of three half-finished surfaces.
Your Android app is stuck on a dead or aging stack
You are on Xamarin, Cordova, an old Android SDK, or a framework you can no longer hire for. We have migrated dead stacks to maintainable Android codebases, reverse-engineering the feature set and teaching your team the new toolchain so you are not dependent on us afterward.
Your Android app needs a backend, not just a UI
A real product needs APIs, a database, auth, and cloud infrastructure behind the screens. We build the full stack: the Android app plus the backend it talks to (Supabase, Next.js APIs, Express, AWS, Azure). When a mobile product has a companion website that needs to stay in parity, we build or maintain it as part of the engagement.
How an Android engagement runs
Four stages. Clear deliverables. You see the plan and the number before build work starts.
Discovery and scope
We pin down what you are building, who it is for, and which Android surfaces matter: phone, tablet, Galaxy Watch.
For a new build we scope features, the right stack (React Native first, Kotlin/Jetpack Compose for native Android where the product needs it), and milestones. For an existing Android app we start with a paid Technical Audit (read-only, standalone) so the work is grounded in what the code actually says. Either way you walk away with a written plan.
Flat-fee proposal
We turn the scope into flat-fee milestones with a fixed number. No hourly surprises.
You see the exact milestone list and the dollar figure before any build work starts. Build engagements start at $25,000 and scale with scope. Deposit plus milestones. If discovery shows the right answer is a longer embedded relationship, we say so and scope it as a Partner engagement rather than stretching a fixed-fee build.
Build and submit
Senior-led Android development, regular builds, a weekly sync, and a path through Play Store review.
We build the app and the backend it depends on, test on real devices across the Android fragmentation landscape, and handle the Play Console submission and review back-and-forth. We design for Play Store policy and the annual target-SDK requirements from the start so your launch does not stall on a policy you did not know about.
Handoff and stability window
Handoff docs to your team, plus a 30-day stability window after handoff.
You get the release-pipeline runbook, the architectural decision records, and the upgrade playbook so your team can keep shipping, exactly as the Xamarin migration team did. A 30-day stability window follows handoff: if something we shipped breaks in production, we fix it.

How much does an Android app development agency cost?
Published anchors, flat-fee milestones, scoped per engagement. No hourly surprises.
Android App Build
Starting at $25,000
Zero-to-Play-Store and scale-ready Android builds for phone, tablet, and Galaxy Watch, in React Native or native Kotlin and Jetpack Compose. Flat-fee milestones, scoped per engagement. Engagements typically run $25k to $200k+ by scope. Includes a 30-day stability window after handoff. Existing apps start with an audit ($2,500 Quick Scan or $5,000 Full Audit).
Building net-new is a Build engagement. Reviving a stalled Android app is audit-first Rescue. A long-term embedded relationship is Partner. We scope to the work, not a package.
