Netofficials builds Kotlin apps for Android, from new products to extensions of an existing app, for growing businesses that need a maintainable, well-tested release. One cross-functional team works from a written discovery scope with a single point of contact. Send a short brief and we will reply with questions and a proposed scope.
You get an Android app built in Kotlin for your customers: sign-in, accounts, payments, notifications and the journeys that bring them back. A technical architect is accountable for system design and code quality standards, so the app can grow with your roadmap instead of needing a rewrite after launch.
You get Kotlin apps for staff, partners or field teams that connect to your existing back end and APIs. Netofficials agrees the integrations and the first-release scope in writing during discovery, so the app fits how your people work and you avoid surprises about what ships first.
You get a clear route from a legacy or hard-to-maintain Android codebase to a Kotlin one. We review what you have, agree what to extend, refactor or replace, and deliver in sprints with a review at the end of each. If cross-platform or iOS-first suits you better, we will say so after scoping.
| Consideration | Kotlin suits best when | We may recommend another approach when |
|---|---|---|
| Platform target | You are building a native Android app and want full access to device features, Android UI patterns and Google Play release tooling. | You need iOS first or one shared codebase for both platforms; after scoping we will say whether Swift or a cross-platform build would serve you better. |
| Team and codebase | You are starting a new Android app, or extending or modernising an existing Java-based one, and want a codebase your team can maintain. | Your in-house team already maintains an app on another stack; we will review it and recommend whether to extend it or move to Kotlin. |
| Backend and integrations | A native Android app that talks to your existing APIs and backend, with architecture and technology choices agreed during design | Your roadmap is iOS-first or needs one shared codebase across platforms; Netofficials will recommend that approach after scoping. |
We turn your Android goals, users, backend and device targets into a written discovery scope that you review before any design begins.
You receiveYou sign off the first-release scope in writing
Our technical architect sets out the Kotlin app structure, API contracts and screen flows for you to review before development starts.
You receiveYou approve the designs and architecture before coding
We build in Agile sprints with Kotlin and Android tooling, and your delivery lead walks you through working builds at the end of every sprint.
You receiveYou review working builds after each sprint
Our QA engineers test the app on agreed Android devices and OS versions against your acceptance criteria, and you receive the results before release.
You receiveYou sign off the Kotlin app against the acceptance criteria agreed in discovery before anything is released.
We release the production build, then hand over documentation and deployment access so your team can maintain and update the Android app.
You receiveYou hold the documentation and deployment access
| Layer | Example choices | Decision to review |
|---|---|---|
| Interface | Kotlin with Jetpack Compose, or Android Views if you maintain an older codebase | Whether the app is new or an extension of existing screens, and how much design-system reuse you need |
| Application architecture | MVVM with Kotlin coroutines and Flow, Hilt for dependency injection | Offline behaviour, background work and how much code your team must maintain after handover |
| API & data | Retrofit or Ktor for API calls, Room for local storage, Kotlin coroutines for background work | Existing backend contracts, offline needs and which team owns the data layer |
| Quality | JUnit unit tests, Espresso or Compose UI tests and an agreed device matrix | Critical user journeys, supported Android versions and release risks |
Send a short brief covering your users, backend and release plans, and we reply with questions and a written discovery scope that sets out what the first release includes.
Fixed-price delivery of a Kotlin Android app with a defined first release, suited to buyers who want the scope and outcome settled before work starts.
A dedicated India-based team that keeps building and extending your Kotlin app release after release, suited to products with a long roadmap.
Kotlin engineers who slot into your in-house Android team, suited to buyers who already run their own process and need specific skills added.
You own it. Netofficials confirms IP assignment in the contract before the build begins, so the Kotlin source code and related work are assigned to you rather than negotiated at the end. At release we also hand over documentation and deployment access, so your team or another vendor can maintain the Android app without depending on us.
Cost and timing are set from a written discovery scope, not a guess. They depend on the number of screens and user flows, backend and third-party integrations, offline or device features, whether you are building new or extending an existing app, and the team size you need. We confirm scope, assumptions and review milestones before delivery starts. If another approach such as cross-platform would suit you better, we say so after scoping.
We agree the communication window, meeting schedule and update cadence with you before work begins, so overlap with your time zone is fixed upfront. A named delivery lead owns day-to-day progress and your communication, and a technical architect is accountable for design and code quality. You also join a client-facing review at the end of every sprint, so you see working progress regularly.
Tell us what the Android app needs to do, who will use it and which backend it connects to. We reply with questions and a written scope, and a named delivery lead stays your contact through to release. We agree the communication window before work begins, and IP assignment is confirmed in the contract before the build starts. If scoping shows that iOS-first or cross-platform fits your plans better, we will say so.
