Our Offerings

Android App Development Services We Provide

01

Native Android Development

Kotlin-first apps using Jetpack Compose, Coroutines, and modern architecture (MVVM, Clean Architecture) that stay maintainable at scale. We optimize for the real Android world — thousands of device profiles and OS versions back to Android 8.

02

Material Design 3 UI

Pixel-perfect interfaces with dynamic color, motion, and adaptive layouts for phones, tablets, and foldables. Material-compliant apps consistently score better in Play Store ratings and reduce user confusion.

03

Google Play Launch & Compliance

Data safety forms, target API level compliance, app signing, and staged rollouts managed end to end. We keep your app ahead of Google's annual target-SDK deadlines so it never gets delisted.

04

Android App Modernization

Migration from Java to Kotlin and from legacy XML layouts to Jetpack Compose, done module by module without freezing releases. Modernized apps see build times and crash rates drop significantly within the first quarter.

05

Wearables, TV & Auto

Wear OS companions, Android TV experiences, and Android Auto integrations that extend your app across Google's ecosystem. We handle the distinct UX constraints and certification requirements of each form factor.

06

Performance & Battery Optimization

Baseline Profiles, startup tracing, memory leak hunting with LeakCanary, and WorkManager scheduling that respects Doze mode. We target cold starts under 1.5 seconds and crash-free rates above 99.5%.

How We Work

What You Get In Writing

Terms that go into every agreement we sign. See all client commitments.

A Written Price Before Work Starts

Every job gets a scope and a number in writing first — a fixed price for defined work, or an hourly rate with a capped estimate. If scope changes, we re-quote before we build, not after.

You Own the Code

Source code, designs, and data are yours. We work in your repository where possible, hand over full documentation, and transfer everything at the end. No license fees, no hostage situations.

NDA Before You Share Anything

We sign your NDA — or send ours — before the first technical conversation. Your idea, your data, and your customer information stay confidential during and after the engagement.

Consumer apps, on-demand platforms, fintech apps with UPI and payment integrations, logistics and field-force tools, and enterprise apps for managed device fleets. All native work is Kotlin with Jetpack Compose; we also support legacy Java codebases.

An Android MVP takes around 3 months; a complete app with backend and Play Store launch takes 4-6 months. Supporting tablets, foldables, or Wear OS adds 2-5 weeks depending on scope.

Typical projects range $12,000 to $50,000 based on feature depth, device coverage, and backend needs. The Google Play developer account is a one-time $25 fee, and Play takes 15% commission on the first $1M of annual in-app revenue.

Yes — full Kotlin source, Gradle configuration, signing keys, and documentation transfer to you, with the app published on your own Play Console account. We sign IP-transfer agreements as standard.

We test on a matrix of 15+ real devices spanning Samsung, Xiaomi, Google, and OnePlus plus Firebase Test Lab's cloud devices. Maintenance plans from $800/month keep your app compliant with Google's yearly target API requirements and new Android releases.

We complete the data safety section, content rating, and store listing, then publish via staged rollout (5% to 100%) to catch issues early. Play review typically takes 1-3 days for new apps; updates usually clear within hours.
