Perfectly tailored to your project
Thanks to modern technologies and cross-platform expertise
Android offers companies a reach that no other operating system can match. With around 70 percent market share among smartphones, it is the go-to platform in B2B industries such as logistics, manufacturing, and field service. Many enterprise devices in these sectors run Android because the operating system can be configured and managed flexibly at scale. If you want to digitize internal processes or put powerful tools in the hands of your workforce, Android is almost always the right starting point.
For over 12 years, Cayas Software has delivered successful Android apps for companies across a wide range of industries. We combine modern technologies like Kotlin and .NET MAUI with a genuine understanding of B2B processes. Our work for companies such as flaschenpost SE, DSP, and CLAAS shows what becomes possible when technical expertise meets real business requirements.
Whether you need a complete project from app design to post-launch support or targeted assistance, you decide how we work together.

Whichever collaboration model you choose, our experts will drive your ideas forward with passion and dedication.
Learn More About Flexible Collaboration
As an experienced Android app development company, we have specialized in two core areas: internal business solutions that optimize processes and customer-facing apps that extend existing products digitally. Need an Android app that your field service team will actually use every day? Or a logistics solution that integrates seamlessly with your ERP system? We bring the experience needed and always advise you honestly on which technology fits your specific situation best.
Many companies run Android apps that are technically outdated or no longer meet current requirements. Often, a full rebuild is not necessary, just a targeted update. We migrate existing apps to modern technologies like Kotlin and Jetpack Compose, bring the UI up to Material Design 3, and ensure long-term maintainability. Optionally, we can extend your existing Android solution to include an iOS version as well.
Discuss Your Android App DevelopmentOne of the most common questions we hear in first conversations. And one we always answer honestly.
The decision between a native Android app and a cross-platform app depends primarily on your use case. Our recommendation, based on over twelve years of project experience:
When native Android development with Kotlin makes sense:
If you rely heavily on hardware features such as Bluetooth, NFC, device sensors, or demanding offline data sync, native is the cleaner choice. The same applies to apps with very high performance requirements, such as real-time camera data processing, or when you only need to cover Android devices.
When cross-platform with .NET MAUI is the better fit:
For most B2B use cases, including field service apps, logistics solutions, data capture tools, and customer portals, we recommend .NET MAUI. We develop once and the app runs on Android and iOS alike. This saves around 30 percent in development time and budget while ensuring all users are covered regardless of their device.

For native Android development, we rely on Kotlin, Google's recommended programming language. Kotlin is modern, concise, and significantly reduces common errors compared to Java. Combined with Jetpack Compose and Android Studio, we build native Android UIs that implement Material Design in full and look great across all screen sizes. For existing projects with a Java codebase, we continue working there and migrate incrementally where it makes sense.
For cross-platform projects, we use .NET MAUI, the modern successor to Xamarin. This allows us to build not only Android apps but also cross-platform solutions for iOS, Windows, and macOS from a single shared codebase. The reusability of code saves you around 30 percent in development time and costs while ensuring consistent functionality across all platforms.
In addition to Android apps, iOS projects are one of our core competencies. Many of our clients start with an Android solution and later expand it to iOS, which is especially efficient with .NET MAUI since large parts of the code can be reused.
By fully utilizing native iOS APIs and reusing business and communication logic, we create an efficient development process with a high return on investment.

Great visions, clever ideas, shared success: why companies trust us. See how we built the Flaschenpost Driver App for thousands of daily deliveries, and how we turned complex telematics requirements into a powerful field app in the CLAAS Telematics App case study.

FAQ
The cost depends primarily on three factors: the scope of features, the complexity of backend integrations, and the range of devices and Android versions to be supported. A straightforward data-entry app for field service will cost significantly less than a fully integrated logistics solution with offline sync and ERP connectivity.
Typical B2B apps start in the mid five-figure range. Android-specific testing across the wide variety of devices adds to the overall effort: we test on a representative selection of manufacturers and screen sizes to ensure your app runs reliably on all relevant hardware.
At Cayas, you receive a transparent quote with no hidden costs and clear milestones from the start. For a detailed overview of cost drivers and realistic price ranges, visit our App Development Costs page.
In most cases, three to five months, depending on the scope. For larger projects, plan for a bit more time; smaller projects can move faster. The development process covers the following phases:
It depends on your use case. Our honest assessment based on twelve years of project experience:
Native Android development (Kotlin) makes sense when you rely heavily on hardware features such as Bluetooth, NFC, or device sensors, need very high performance, or are building exclusively for Android.
Cross-platform with .NET MAUI is the better fit when your app needs to run on both Android and iOS, you are building a field service app, customer portal, or data capture tool, and time and budget are relevant factors. We develop once and deploy to both platforms, saving around 30 percent in development time and cost.
We give you a clear recommendation in a free initial consultation. More details are available on our cross-platform app development page.
For native Android development we use Kotlin, Google's recommended programming language. Kotlin is modern, concise, and significantly reduces common errors compared to Java. Combined with Jetpack Compose, we create native Android UIs that fully implement Material Design and look great on all screen sizes.
For existing Java-based projects, we continue working in Java and can migrate incrementally to Kotlin wherever it makes economic sense.
For cross-platform projects, we use .NET MAUI with C#, enabling a shared codebase for both Android and iOS. This approach reduces development time, lowers costs, and keeps behavior consistent across platforms.
Publishing on the Google Play Store involves the following steps:
We manage the entire submission process so your app is correctly configured and optimized for all relevant devices when it appears in the store.
Yes, absolutely. Many companies run Android apps built on outdated technologies or with a UI that no longer meets current standards. A full rebuild is often not necessary; a targeted update gets the job done more efficiently.
We handle migration to modern technologies like Kotlin and Jetpack Compose, updates to Material Design 3, and selective feature additions. We also migrate older Xamarin apps to .NET MAUI to make them future-proof. We always give you an honest assessment of whether an update or a full rebuild makes more sense economically for your specific situation.
