Android App Development Services
Four tracks inside every Android engagement.
Choose one to see the stack, the platform APIs and what it buys you.
Native Android in Kotlin, Jetpack Compose and Material 3.
API 24+
supported baseline
Our core practice. Compose UI, MVVM with coroutines and Flow, Room for offline-first data, WorkManager for background jobs, and motion that matches the OS. Built to Google Play policy so review is a formality, not a gamble.
- Compose-first UI with dark theme and dynamic colour
- TalkBack, font scaling and large-screen layouts handled
- Widgets, deep links, shortcuts and share targets
Stack we use
Straight Answers
Stack, store, ownership.
Four decisions every app owner has to make, answered without the sales layer.
Native Kotlin, Flutter or React Native?
Kotlin when the app leans on hardware, heavy data, animation performance or long-term platform depth. Flutter when Android and iOS must ship together with one UI language and a tight budget. React Native when your team already lives in JavaScript and you want to share logic with a web product. We recommend based on your feature list, not on what we prefer to bill.
How is Google Play release handled?
We prepare the signed AAB, Play Console listing, screenshots, content rating, Data safety form and privacy policy links, then publish under your own developer account and answer any policy rejection ourselves. Most releases clear the first review because policy checks happen during QA, not after submission.
Who owns the Kotlin code and the Play account?
You do. The repository is yours from the first commit, the app is published under your own Google Play developer account, and design files, keystores and pipelines transfer to your team on payment. Nothing is tied to ACSIUS for version two.
Can you take over an existing Android app?
Regularly. We start with an architecture, dependency and ANR/crash audit, then send a prioritised list of defects, technical debt and quick wins with effort estimates. Work happens on a branch with CI so your live app keeps serving users while we stabilise it.
Ways To Engage
Three ways to start, one written scope.
Android MVP sprint
Kotlin app with 4–6 core screens, one integration, analytics and an internal-testing release. Built to be used by real users, not to win an award.
- Best for
- Founders and new product bets
- Timeline
- 6–8 weeks
Full Android product
App, backend, admin dashboard, payments, push, deep links, QA coverage and Play launch under your own developer account.
- Best for
- Funded startups and SMBs
- Timeline
- 3–5 months
Dedicated Android pod
Hire Android developers in India as an embedded pod — engineers, designer and QA in your standups, sprints and repo, scaling month to month.
- Best for
- Enterprise and product teams
- Timeline
- From 1 month
How We Build
Idea to Google Play in six phases.
Every phase ships something you can open, tap or install. No hidden gates.
- 01Week 1–2
Product & platform scope
Workshops on users, journeys and must-have vs later. You leave with a feature list, an Android version baseline and a written phased scope.
Scope doc + roadmap
- 02Week 2–3
Mobile UX prototype
Clickable prototype of the core journeys using Material patterns, tested on a real handset before a line of Kotlin is written.
Figma prototype
- 03Week 3–4
Material design system
Components, states, empty states, icons, motion and theme tokens — a Compose-ready system your future engineers extend instead of redraw.
Design system
- 04Week 4–9
Kotlin sprint engineering
Two-week sprints across app and backend, each closing with a signed APK or internal-testing build on your own phone.
Weekly installable builds
- 05Rolling
Real-device & policy QA
Functional, performance, battery, accessibility and Play policy passes across low-end and flagship handsets, tablets and multiple OS versions.
Test + policy report

Play launch & rollout
Listing, screenshots, signing, Data safety, submission, staged rollout, crash monitoring and 30 days of post-launch support.

Need installs, not a website?
One landing page + Google Ads to drive app installs.
Plenty of app owners only need a single high-converting page: a place for Google Ads, App campaigns and social traffic to land before the Play Store button. We design, build and run it as a standalone package.
Single conversion page
One page — hero, proof, screenshots, FAQ and install buttons. Live in days, no CMS to learn.
Google Ads & App campaigns
Search, Performance Max and Google App campaigns structured around install and signup intent.
Tracking that actually works
GA4, Firebase and install or first-open conversions wired before a rupee of spend goes out.
Creative & A/B testing
Ad copy, store creative and two hero variants tested weekly so cost per install keeps falling.

Crash gate
Play policy handled
Signing, Data safety, content rating, listing and review replies are our job — published under your own Google Play developer account.
Weekly installable builds
From sprint two you install the real app on your own phone every week. Progress you can tap beats a status report you have to trust.
Real device coverage
Low-end and flagship handsets, tablets, multiple Android versions and slow networks — because your users are not on your dev phone.
Your repo, your keystore
Kotlin code in your Git from the first commit, keystores and pipelines handed over, no lock-in to us for version two.
Performance budgets
Cold start, APK size, ANR rate and battery drain are tracked as release gates, not discovered in a one-star review.
We stay after launch
30 days of free post-launch support, then care plans covering annual Android releases, SDK upgrades, crash triage and iteration sprints.

No lock-in, no hidden phases, no demo theatre.

Talk to an Android LeadSixteen years of delivery, an in-house salaried team of 40+ designers and engineers in New Delhi, 120+ mobile apps in production, and a method built on weekly installable builds instead of monthly slide decks. We publish under your own developer account and hand over Kotlin source code, so our record has to stand on its own rather than on lock-in.
Discovery and scoping, mobile UX and Material design systems, native Kotlin and Jetpack Compose engineering, Flutter and React Native builds, backends and APIs, payments and push, QA across real devices, Play Console release with Data safety and content rating, and post-launch support plans.
Yes. Our studio is in Hasanpur, New Delhi 110092, and clients across Delhi NCR — Noida, Gurugram, Ghaziabad and Faridabad — visit for scope workshops, sprint demos and device testing. Clients outside NCR get the same cadence over video with a named Android lead and recorded notes after every session.
It depends on screen count, integrations and whether a backend is in scope, so we quote against a written feature list rather than a page price. Send your idea or a reference app and within two working days you get a phased scope with what belongs in v1, what can wait, and a milestone-based commercial plan.
Discovery and UX take 2–3 weeks, a focused MVP 6–8 weeks, and a full-feature Android product 3–5 months including QA and Play review. You install a signed build every sprint from week four, so timelines are verified by working software rather than percentages.
Both, and we recommend the honest option. Native Kotlin with Jetpack Compose when the app needs hardware access, animation performance, offline data or deep OS integration. Flutter or React Native when Android and iOS must launch together and the interface is largely lists, forms and dashboards.
Yes. We prepare the signed AAB, listing copy, screenshots, content rating, Data safety declarations and privacy links, then submit and manage review under your Play Console account. If you also need iOS, the same team handles App Store submission.
Every project includes 30 days of free post-launch support. After that, care plans cover annual Android releases, target-SDK deadlines, Play policy changes, crash and ANR triage and a monthly change report, with iteration sprints whenever you want new features.
Always, before any code or product detail changes hands. Access is least-privilege, credentials stay in your vault, and delivery can be aligned with HIPAA or GDPR requirements when your sector needs it.
