Why teams choose Sosene as their Android app development company
As an Android app development company, we know the hard part. Android runs on thousands of devices, screen sizes and OS versions. So one app has to work well on all the ones that matter to you. That is why our engineers build natively in Kotlin, with AI inside the daily workflow. In addition, a named lead signs off every release.
Built for the devices you actually face
We agree a device and OS matrix from your analytics, then test against it on real hardware and emulators. AI also drafts the edge cases that manual testing tends to skip.
Modern Android, not legacy patterns
Kotlin, Jetpack Compose and the current architecture components by default. Older Java or XML screens get migrated in steps, without freezing new features.
Faster from brief to Play Store
AI drafts boilerplate, unit tests and release notes. As a result, engineers spend their hours on the parts of your app that need judgement.
A team that stays after launch
New Android versions, new devices, new policies from Google. The same engineers handle updates, so nothing gets relearned from zero.

Android apps that stay fast on mid-range phones
Many of your users are not on flagship devices. So we profile startup time, memory and battery use from the first sprint, and we keep the app size down. We also handle weak networks with offline states and retries. As a result, the app holds up on the phones people really buy.
What our Android app development company offers
As your Android app development company, we can join at any stage: a new app, a rebuild, or a product already live on Google Play.
Native Android app development
New apps in Kotlin and Jetpack Compose, structured so features can be added without rewrites.
Android UI/UX design
Screens that follow Material Design and feel familiar to Android users, prototyped and tested before code.
Migration and modernisation
Java to Kotlin, XML layouts to Compose, and outdated libraries replaced one module at a time.
Backend and API integration
Connecting your app to payments, maps, push notifications, analytics and your own APIs.
Testing and quality assurance
Unit, UI and device-matrix testing, with AI generating test cases and the QA engineer deciding what ships.
Google Play release and maintenance
Store listing, staged rollouts, crash monitoring and policy updates, handled release after release.
Three ways to work with an AI-driven team
The commercial model changes with your goals. The way the team works does not.
AI-assisted full outsourcing
Project-based delivery
We take ownership of the whole project, from discovery and solution design through build, testing, deployment and launch. Delivery runs under agile governance, with AI applied to requirement analysis, development support, QA preparation, documentation and reporting. A named engineer signs off on every output.
AI-driven dedicated agile team
A standing team with committed sprint outcomes
A dedicated agile team aligned to your roadmap and your backlog. Sprint deliverables are planned and agreed with you against your priorities, backlog readiness and team capacity. The team applies AI across the lifecycle, from requirement analysis and user stories to coding, QA, documentation and sprint reporting.
AI-enabled staff augmentation
Specialists under your direction
Technology professionals who join your in-house team and work under your direction, process and management. They bring the technical depth you asked for plus AI-assisted working methods, which shows up as faster development, better documentation and stronger test preparation.
How an Android project runs with Sosene
Our Android app development company works in six stages, adjusted to where your product is today.
01 Discovery
First, we review your goals, users and analytics. Then we agree the target devices and Android versions.
02 Design
User flows and Material-based screens, tested as clickable prototypes before development starts.
03 Architecture
App structure, data layer and API contracts, written down so any engineer can pick them up.
04 Build and test
Short sprints with CI builds, automated tests and a demo you can install at the end of each one.
05 Release
Play Store preparation, a staged rollout to a share of users, and close crash and review monitoring.
06 Support
Updates for new Android versions, device issues and feature requests, by the team that built it.
What keeps delivery predictable
Speed only counts if the result holds up. These practices sit behind every engagement, whichever model you choose.
Project foundation
- Scope defined together, in writing
- A team composed for the work, not the average
- Roadmap and milestones agreed up front
Cost control
- A transparent estimation method
- Build order driven by business value
- Savings that never come out of quality
Collaboration
- One communication framework, not five
- Roles and responsibilities named per task
- Regular alignment with your stakeholders
Risk management
- Risks identified before the build starts
- Continuous monitoring through the lifecycle
- A named owner for each mitigation
Change management
- A single route for change requests
- Impact assessed before anything is committed
- Approved changes scheduled without drama
Quality assurance
- Success metrics agreed at the start
- KPI reporting you can check yourself
- Improvement cycles between releases
Knowledge transfer
- Structured documentation, kept current with AI
- Handover built into the plan, not bolted on
- Technical specifications written to be used
After launch
- Warranty coverage on what we deliver
- Maintenance options that match your load
- The same team available for the next phase
Frequently asked questions
Do you build Android apps natively or cross-platform?
Both. Native Kotlin gives the best performance and full access to Android features. However, if you also need iOS and your app is not hardware-heavy, a cross-platform build with Flutter or React Native can save time. So we recommend one only after looking at your requirements.
Which Android versions will my app support?
We set the minimum version from your own user data and market, not a fixed rule. Supporting very old versions costs extra testing, so we show you the trade-off before deciding.
Can you take over an existing Android app?
Yes. As an Android app development company used to inheriting code, we start with a code and architecture review. Then we fix what blocks releases and continue development. AI also helps us document an unfamiliar codebase quickly.
Will you publish the app to Google Play for us?
We prepare the build, listing and release, and publish under your own developer account, so the app and its data always belong to you.
How Android app development engagements are priced
Two commercial models, and one honest answer about numbers.
| Fixed price | Time and materials | How we reach a number |
|---|---|---|
| One price agreed in the contract. It fits feasibility studies, proofs of concept and small pieces of work where the requirements are settled and unlikely to move. | You pay for the hours worked each month, with an optional cap that sets a ceiling for budget control. This suits advisory work, business analysis, architecture and planning, agile delivery, and modernising software you already run. | Every estimate starts with a short discovery call. You get a written proposal with named engineers, a delivery timeline and a price before anything is committed. Cost depends on scope, integrations and compliance requirements, so we quote per project rather than from a list. |
