Teams leave an Android development engagement with a production-ready Kotlin codebase, documented architecture, and a Google Play-approved app — structured for maintenance and extension.
We build with Jetpack Compose, implement UI from Figma, and handle everything from the first commit through Play Store submission.
3 main challenges holding back your growth
Outgrown identity
Your company has grown, but the brand no longer reflects scale or direction.

No defined app architecture
No architecture — maintenance costs compound from release one.

Design intent lost in code
UI implemented inconsistently — design intent lost between Figma and code.

No engineering handoff
No handoff docs — new engineers take weeks to understand the codebase.

FAQ
Why invest in branding services?
Why invest in branding services?
What does Android development include?
App architecture, native Kotlin development, UI implementation with Jetpack Compose, API integration, push notifications, QA testing across devices and manufacturers, Google Play submission, and handoff.
Do you use Kotlin or Java?
Kotlin is our primary language for all new Android development. Java is supported for projects requiring integration with existing legacy codebases that have not yet been migrated to Kotlin.
Can you implement our Figma designs?
Yes. UI implementation is pixel-aligned to your Figma specifications — component structure, spacing, interaction states, and motion behaviour all matched to the design handoff using Jetpack Compose.
How long does Android development take?
Most Android MVP builds take 3 to 5 months from architecture to Google Play submission, depending on feature scope, backend complexity, and whether design is included in the engagement.
Do you handle Google Play submission?
Yes. We prepare all Play Store assets — screenshots, store listing, content ratings, privacy policy compliance, and Play Console configuration — and manage submission through to approval.
Which Android versions do you support?
We target Android 8.0 and above by default, covering the majority of the active device base. Specific version support is scoped during architecture planning based on your target user analytics.
Do you integrate third-party APIs?
Yes. REST and GraphQL API integration — including authentication, payment providers, analytics, push notification services, and other third-party dependencies — are built as part of development.
Do you write unit and UI tests?
Yes. Unit tests and UI tests are written during development using JUnit and Espresso — covering critical business logic, API interactions, and key user flows before the app reaches Google Play.
Do you offer post-launch support?
Yes. Ongoing Android development retainers are available — covering new feature builds, Android version updates, device compatibility fixes, and Play Store asset updates as your product evolves.
