“TechInfini's developers were very skilled and engaged. Users said the app successfully integrated with the exercise machines and accurately got data from them.”
Android App Development
Native Android apps in Kotlin — built for the full device range and shipped to the Play Store.
The full
picture.
Android app development reaches the largest mobile audience in the world — but only an app built for the full range of Android devices performs well for all of it. TechInfini builds native Android apps in Kotlin, engineered for performance and built to Play Store standards. We have delivered more than 500 projects since 2008.
What native Android development delivers
A native Android app, built in Kotlin, gives the best performance, the smoothest experience and full access to device features — camera, location, notifications, sensors and offline storage. It follows Material Design so the app feels familiar to Android users, and meets the Play Store guidelines that govern approval and visibility.
Native also means the app keeps pace with the platform. New Android versions and device types are supported quickly, rather than leaving users on an app that slowly falls behind.
How TechInfini builds Android apps
We define the product, users and success metrics, design the flows and screens, and build in focused sprints with installable builds you can try at every stage. The app is tested across a representative range of real devices, screen sizes and Android versions, and we prepare the store listing and manage submission through Play Store review to approval.
After launch we monitor crashes and performance and support new Android releases, so the app stays stable as the platform moves.
Where native Android development works best
A native Android build is the right choice when performance, device features or reach across the full Android market are central to the product.
- Apps that need top performance and smooth animation
- Apps using device hardware — camera, GPS, sensors, Bluetooth
- Apps that must work reliably offline
- Apps targeting the full range of Android phones and tablets
- Consumer apps where store ratings drive growth
- Apps that need fast support for new Android versions
If you also need an iOS app and the budget is tight, a cross-platform build may serve you better — and TechInfini will say so during discovery rather than default to two native apps.
Performance across the Android ecosystem
Android is not one device but thousands — different screen sizes, chipsets, manufacturers and OS versions. An app that runs well only on a recent flagship is an app that fails for a large share of its users.
TechInfini builds responsive, efficient Android apps and tests them across a representative range of real devices and Android versions, so the experience holds up from budget phones to the latest hardware.
What to expect from Android app development with TechInfini
Every Android app development project runs to the same standard. It starts with a clear discovery and a fixed, transparent scope, so the timeline and cost are known before the build begins — and the senior engineers who scope the work are the ones who build it.
Through the build you get regular, installable releases to try, not a long silence followed by a single reveal. Android app development at TechInfini is tested across real devices and Android versions as it goes, so quality is built in rather than checked at the end.
Android app development also does not end at launch. The app is documented and fully handed over, you own the source code and the Play Store account, and TechInfini stays available for updates, new OS support and the next features. A good Android app development project keeps performing long after release.
Why choose TechInfini for Android app development
Every Android app is built by a senior-led pod, with performance and retention designed in from the start. You own the complete source code and Play Store account, handed over clean and documented. To scope an Android app, book a free estimate, or explore the wider mobile app development service.
Why teams
choose us.
Senior-led delivery
Every app is built by a senior-led pod, so architecture decisions are made by engineers who have shipped to the stores before.
The right stack for your budget
We recommend native or cross-platform honestly, based on your product — not on what is easiest for us.
Built for retention
Performance, smooth UX and thoughtful onboarding are designed in from the start, because installs only matter if users stay.
You own the app
Source code, store accounts and assets are all yours, documented and handed over clean — no lock-in.
18+ years shipping software
500+ projects delivered since 2008 means your app is built on proven engineering, not guesswork.
Our delivery process.
Discovery & platform choice
We define the product, users and success metrics, and recommend native or cross-platform for your case.
UX & prototype
We design the flows and screens and build a clickable prototype so you can validate before development.
Development
We build the app in focused sprints with regular, installable builds you can try at every stage.
Testing & QA
We test across real devices, OS versions and network conditions for performance, security and edge cases.
Store launch

It depends on your audience. Android has the larger global user base, while iOS users tend to spend more per app and are concentrated in some markets. If budget is tight, a cross-platform build covers both at once. TechInfini recommends the right approach based on where your customers actually are.
Android runs on thousands of device and screen combinations. TechInfini builds responsive layouts, tests across a representative range of real devices and Android versions, and follows Material Design and Play Store guidelines so the app performs reliably from budget phones to flagships.
The cost of a mobile app depends on its features, the number of platforms, and whether it is native or cross-platform. A focused first version is far cheaper than a full-featured app, and choosing one cross-platform codebase over two native builds can reduce cost significantly.
TechInfini scopes every app with a clear, itemised estimate before work begins.
A straightforward mobile app typically takes two to four months from design to store launch, while larger apps with complex features or integrations take longer. A cross-platform build is usually faster than two separate native apps.
TechInfini provides a phase-by-phase timeline during discovery so you know what to expect.
Yes. TechInfini handles the full release process — preparing store listings, screenshots and metadata, configuring developer accounts, and managing submission through Apple App Store and Google Play review to approval. We also support post-launch updates and new releases.
Yes. You own the complete source code, design files and store accounts for your app. Everything is documented and handed over to your team at the end of the project, so there is no vendor lock-in and you are free to maintain or extend the app however you choose.
Yes. TechInfini offers ongoing maintenance — monitoring crashes and performance, supporting new Android and iOS versions, applying security updates, and building new features. Mobile platforms change constantly, so regular maintenance keeps an app stable, secure and available in the stores.
TechInfini builds security in from the start — encrypted data storage and transmission, secure authentication, safe handling of API keys, and compliance with App Store and Play Store privacy requirements. Security is tested before launch and maintained through updates as platform requirements evolve.
