Native Android Development For Maximum Control

An app fully optimised for the Android platform and every device.

Android is the most widely used mobile operating system in the world. But the platform is also the most fragmented — thousands of different devices, screen sizes and Android versions running simultaneously. A native Android app gives you the control to perform consistently across all that variation. No compromises, no limitations.

We build native Android applications with Kotlin, the Google-recommended language for Android development. Kotlin combines the power of Java with modern language features that lead to cleaner code, fewer bugs and faster development. The result is an app that runs smoothly, responds quickly and feels like a natural part of the Android ecosystem.

Native development means your app has full access to all Android functionalities. Camera, GPS, biometric authentication, push notifications, NFC, Bluetooth — everything is directly available without workarounds. That delivers a user experience that cross-platform solutions cannot match.

  • Built with Kotlin, the modern standard for Android
  • Full access to device camera, GPS and sensors
  • Optimal performance on every Android device
  • Native UI components that feel like part of Android
  • Direct integration with Google Play Services

Why Choose Native Android Development

The benefits of an app built entirely for the Android platform.

Cross-platform solutions like Flutter and React Native have their place, but native Android development offers unique advantages when you want to get the most out of the platform. The app runs directly on the operating system without intermediate layers, resulting in faster loading times, smoother animations and lower battery consumption.

In addition, a native app always gets first access to new Android features. When Google releases a new API — such as Machine Learning Kit, ARCore or improved notification options — your native app can use it immediately. With cross-platform, you have to wait until the bridge to that functionality has been built.

For apps that make intensive use of device functionality — such as camera applications, navigation tools, augmented reality or IoT connections — native development is the only choice that delivers the desired quality and responsiveness.

  • Highest performance without intermediate layers or bridges
  • First access to new Android APIs and features
  • Smoother animations and faster rendering
  • Lower battery consumption through more efficient code
  • Deeper integration with the Android ecosystem

How We Build an Android App

A proven process from strategy to Play Store publication.

01

Introduction & Analysis

We discuss your objectives, target audience and desired features. We analyse your market and determine the best technical approach for Android.

02

Project Plan

We translate the analysis into a concrete plan with features, architecture and timeline. You know exactly what to expect.

03

UX Design & Prototyping

We design the user flows following Material Design 3 guidelines. You see and feel how the app works before we write a single line of code.

04

Native Development

Our development team builds the app with Kotlin and modern Android architecture. Components are tested for reliability and performance.

05

Backend & Integrations

We build the server-side infrastructure and connect your existing systems such as CRM, ERP or databases through API integrations.

06

Device Testing

We test the app thoroughly on different Android devices, screen sizes and versions. Bugs are identified and resolved.

07

Play Store Publication

We handle publication in Google Play Store. Including optimised store listing, screenshots and all technical requirements.

08

Aftercare & Further Development

Even after launch, we are available for maintenance, updates and new features. We monitor crashes, performance and user feedback.

Why Choose Speedy Systems

We combine Android expertise with broad software knowledge.

Speedy Systems is not a standard app agency. We are a software company that builds Android applications with the same technical depth as our custom software. That means: clean Kotlin code, a well-considered MVVM architecture and solutions that scale to hundreds of thousands of users.

Our team understands that an Android app is more than just the frontend. The backend, API integrations, database design and security must all work together into a reliable whole. We have experience with complex integrations, real-time synchronisation and apps that must perform under heavy load.

We believe in long-term relationships. Many of our clients have been working with us for years — not because they are tied to a contract, but because they value the quality and reliability we deliver.

  • Native Kotlin development with modern Android architecture
  • Deep experience with backend and API integrations
  • Transparent communication with dedicated contact persons
  • Thorough device testing across hundreds of Android configurations
  • Ongoing support and maintenance available
  • Scalable architecture that grows with your user base

Frequently Asked Questions About Android App Development

Answers to the questions we receive most often.

What is the difference between native Android and cross-platform?

Native Android apps are built with Kotlin and run directly on the Android operating system. That offers the best performance, full access to device functionality and the smoothest user experience. Cross-platform apps (such as Flutter) run on both Android and iOS with a single codebase, but do not offer the same depth of platform integration. The choice depends on your requirements for performance and device integration.

How long does it take to develop an Android app?

A standard Android app is delivered within 8 to 12 weeks. More complex applications with extensive backend systems, real-time synchronisation or multilingual support take 14 to 20 weeks. The exact timeline depends on the number of features and integrations.

What does a native Android app cost?

A native Android app starts from €12,500. This includes design, development, testing and Play Store publication. More complex applications with backend systems and integrations start from €25,000. We always provide a custom quote after a no-obligation conversation.

Will my app be published in Google Play Store?

Yes. We handle full publication in Google Play Store. Including optimised store listing, screenshots, descriptions and all technical requirements. We also advise you on Play Store visibility and app store optimisation for maximum discoverability.

How many devices is the app tested on?

We test on a wide range of Android devices, including phones from Samsung, Google Pixel, OnePlus and Xiaomi. We test on different screen sizes, Android versions (from API level 24) and hardware configurations to ensure a consistent experience.

Can my Android app be connected to my existing systems?

Absolutely. We build connections with your CRM, ERP, databases and other business systems through REST API integrations. Whether it is Exact, Twinfield, Salesforce or a custom system — we ensure seamless integration with real-time or synchronised data.

What if I want to serve both Android and iOS?

You have two options: native development for both platforms (two separate apps with Kotlin for Android and Swift for iOS) or cross-platform with Flutter. Native offers the best experience per platform, Flutter saves development time and costs. We advise you on the best approach for your situation.

Do you offer maintenance after launch?

Yes. We offer maintenance contracts including Android version updates, security patches, bug fixes and new features. We monitor crash reports via Firebase and proactively respond to changes in the Android ecosystem.
