Native Android development
Phone and tablet apps in Kotlin on current Android frameworks and guidelines, with existing Java code maintained or moved to Kotlin step by step.
ServiceView moreNative Android apps in Kotlin for products that need the platform at its best across the whole range of Android devices. When you need iOS too, we recommend Flutter or React Native and write Kotlin where a feature demands it.

ServiceView moreBusiness analysis, design, QA, Google Play review and releases on a schedule, then maintenance and new features as Android moves on.
ServiceView moreAI in this service
AI on Android runs both in the cloud and on the device. Three ways it changes what your app can do.
Chat and voice assistants, document and photo recognition and search that understands intent, built on OpenAI and Claude models with your data kept under control.
On-device machine learning on Android handles tasks such as text and image recognition locally, so some features work offline and private data stays on the phone.
AI-assisted development shortens the build; senior engineers own the architecture and review every line before it reaches Google Play.
Why Qberry
We write Kotlin where it improves the product and recommend cross-platform where it does not, so the budget goes where users feel it.
Analysis, design, development, QA and release come from one team, so nothing gets lost between vendors.
Layouts, performance and testing cover the wide range of Android phones and tablets, not just the latest flagship.
Kotlin for the platform, cross-platform where it saves, AI and automation behind the screens.

View detailsBuilding custom apps for Android phones and tablets: business analysis, design, app and server-side development, QA testing, the Google Play release and support. Today that usually includes AI features and an automated backend.
Besides building the app, we design it, test it, publish it and maintain it after release, and we add AI features and automation to existing Android apps where their code allows it.
Look at the team's real experience with payments, in-app communication, cloud infrastructure and app security, and check that design and QA are part of the service. Ask how they use AI in development and who reviews every change.
Check the portfolio, talk to previous clients and look at the stack: Kotlin for native work, with Java for older code, and Flutter or React Native for cross-platform apps. A good partner also tells you honestly when a separate native app is not needed.
Business analysis with documented requirements, UI/UX design with wireframes, app and server-side development, the Google Play release, and maintenance or new features when you need them.
Apps for e-commerce, media and online marketplaces, business systems such as ERP, HRM and CRM for larger companies, and AI assistants and tools that work with company data.
