Android Applications

We help you turn your idea into a fully functional Android application – from the first prototype to publishing in Google Play. We build apps that are fast, stable, well-thought-out and adapted for real-world usage, not just “for demo purposes.”

Why a responsive website is not enough

A responsive website is a great foundation, but in many cases it’s not enough. If you need offline features, notifications, camera or microphone access, sensors, or deeper device integration, a mobile app is the natural next step. An Android app becomes a stable channel — always available in the user’s pocket.

When designing an Android app, we look at:

  • what the app should actually deliver to users,
  • where it complements the website and where it can replace it entirely,
  • which features must work offline,
  • what data will be synchronized,
  • how the app will grow over the next 2–3 years.

Design and user experience (UI/UX)

An Android app must be fast, intuitive and feel natural within the system. We follow Material Design principles, use proven patterns and respect your brand’s visual identity. The goal is simple: the user must always know what is happening, where to tap and how not to get lost.

In UI/UX we focus on:

  • clear navigation and logical screen structure,
  • readable typography and proper contrast for dark and light modes,
  • micro-interactions — animations, transitions, user feedback,
  • clear loading, error and connection states,
  • ergonomics — single-hand use and proper placement of elements.

Modern technologies – Kotlin, Jetpack, Clean architecture

We develop applications in Kotlin using modern Android libraries and architectural principles. In practice, this means more stable code, easier maintenance and the ability to expand the app without rewriting it entirely.

Technically, we rely on:

  • Android Jetpack (ViewModel, LiveData/Flow, Navigation, Room, etc.),
  • clean architecture (MVVM / Clean, modularization when needed),
  • secure storage and network operations (HTTPS, tokens, encryption),
  • performance and battery optimization,
  • preparedness for new Android versions and device types.

Integration with backend and website

One of our strongest advantages is connecting Android apps with custom backend and websites. We design systems where the website, API and mobile app are not three separate worlds, but a single coordinated ecosystem.

In practice, this means:

  • API built on the JOTO.sk Mini-Framework or your existing backend,
  • standardized JSON output and clearly defined endpoints,
  • secure authorization (tokens, roles, access rights),
  • content and user management through a web administration panel,
  • shared data between the website, app and other systems.

Notifications, offline mode & special features

Android apps can go far beyond what a typical website can do. We create solutions that take advantage of platform-specific capabilities — from notifications to hardware access.

Typical scenarios:

  • push notifications (news, orders, messages, reminders),
  • offline mode with local data storage and delayed synchronization,
  • camera usage (scanning, documents, product photos),
  • maps, location, sensors, Bluetooth and Android Auto integration,
  • AI features — voice assistants, text generation, content processing.

Publishing on Google Play & maintenance

Navigating the Google Play ecosystem can be challenging. We help you with the entire process — from preparing builds and testing to publishing and ongoing updates.

We can ensure:

  • release builds, signing and changelogs,
  • internal and closed testing setup,
  • descriptions, screenshots and graphics for Google Play,
  • crash monitoring and error reporting,
  • regular updates and feature expansion.

A human approach – development as a partnership

We don’t want to just “code an app and hand it over”. We aim for long-term collaboration — from the first MVP, through user feedback, to versions 2.0, 3.0 and beyond.

With our Android development you get:

  • help defining features and priorities (what makes sense first),
  • clear explanation of technical options in simple language,
  • flexibility — the ability to expand in smaller modules,
  • a technological partner who understands both code and business,
  • certainty that Android won’t be separated from your website and systems.

Conclusion – when you want an app that truly matters

If you’re considering an Android app that should become a real tool — not just a “nice icon” — we’re ready to help. Together, we will set up the concept, technology stack and long-term growth plan so that the app evolves with your project.
