Mobile App Development Services

We build native and cross-platform mobile applications for iOS and Android - a fintech app for Avafin, Android work at the AOSP level for Mudita, and a custom secure mobile operating system for RAW Cyber.

Why Companies Choose Mobile App Development

Higher Availability

A mobile app lives on the device your customer already carries everywhere, so reaching them no longer depends on them remembering to open a browser and type your address.
 

Analytics at Your Fingertips

An app records what people actually view, use, and abandon inside your product, turning assumptions about customer behavior into a data source your team can query.
 

Reach Wider Audiences

App stores, push notifications, and mobile-first users are a distribution channel a website-only product doesn't have. Our native and React Native builds, like Avafin and Zeronest, run on that channel today.
 

Proven on Real Mobile Products

RAW Cyber - Secure Mobile Operating System

Our main mobile proof point is RAW Cyber: we built a secure custom mobile operating system from the ground up, not just an app running on top of an existing one. Over three years, that meant a custom Android OS hardened with CopperheadOS, packet inspection to detect and block malware, and a secure, pre-approved app store, delivered by a full Scrum team of engineers, a tech lead, a UX/UI designer, a QA tester, and a Project Manager. Read the full RAW Cyber case study below for more detail.

RAW Cyber - Secure Mobile Operating System
"Even with the challenging demand, the team was able to provide designs and other OS features already. The team managed to deliver on time and they understand the specifics of the security industry."

Recent Work and How We Deliver It

Mudita: Android at the AOSP Level

For Mudita, our team works on Android at the AOSP level - the layer of the Android operating system itself, below the apps a user installs. Part of that work has been migrating pieces of the product to a new Android architecture.
 

Avafin: Fintech iOS & Android App

For Avafin, a fintech company, our team builds native iOS and Android features for a product used to manage real money.
 

React Native: Zeronest and AASA24SUP

Our React Native work sits alongside this native and AOSP engineering: one codebase serving both iOS and Android users on our cross-platform projects, instead of maintaining two separate native codebases.
 

Who Builds This: Your Mobile App Development Company

Every mobile project gets a team shaped by what it needs - typically a Project Manager, UX/UI Designer, QA Tester, and front-end and back-end Developers. We work in Scrum sprints with regular demos, so you see working software at each step of the project.

Native iOS and Android apps, or one React Native codebase for both platforms - built around what your product actually needs.

Native, Hybrid, or Cross-Platform: Why Build With Us

Native Apps

Native Apps

We build native applications end-to-end, separately for Android and iOS, so each platform gets an experience tuned to how its own users behave - the approach behind RAW Cyber and our Avafin and Mudita work.

  • Native (Swift/Kotlin): deep OS access, top performance, security-critical apps - proven on RAW Cyber, Avafin, Mudita.
  • React Native: one codebase, faster and cheaper for most business apps - proven on Zeronest, AASA24SUP.
Hybrid & Cross-Platform Apps (React Native)

Hybrid & Cross-Platform Apps (React Native)

One React Native codebase runs on both iOS and Android, so you maintain a single codebase instead of building and maintaining two separate native apps.

Usability and Simplicity

Usability and Simplicity

We use the same UX/UI process we ran for RAW Cyber's secure OS interface and Avafin's fintech app, built around making data easy to reach so new users get a smooth first session.

Let's book a meeting

  • We build native apps for iOS and Android, and cross-platform apps with React Native, our primary framework for that - plus Xamarin, Ionic, and Flutter when a client's existing stack calls for them.

  • We develop both. Hybrid apps are built to run across platforms from one codebase, while iOS and Android native apps are built separately for their own operating systems.

  • Team composition depends on the project's needs. Depending on the project, your team can include a Project Manager, UX/UI Designer, QA Tester, and front-end and back-end Developers.

  • Our documented mobile app development process runs from brief workshops to releasing the product, split into sprints: strategy, planning, UI/UX design, information architecture and workflows, wireframes, prototype, development, testing, deployment, support. Each stage breaks down into tasks and resources we use as a roadmap for the project.

  • Yes. We work in Scrum sprints with transparent reporting at every stage, and a routine demo at the end of each sprint so you always know what's being built and why.

  • A typical project takes about 7 months: roughly 1 month to organize the team, 1-2 months for product and design workshops, and 2-4 months for product development and testing. For your specific timeline, send us an estimation inquiry and our team will follow up with a concrete answer.

  • The minimum budget is 25,000 EUR per platform - we don't take on smaller projects. Contact us for an estimate specific to your app.

  • You can bring in a single specialist for your project or hire a dedicated development team, working under one roof for direct, day-to-day communication and the ability to adjust scope as you go.

  • React Native is our primary framework for cross-platform apps - used in production on Zeronest and AASA24SUP, where one codebase serves both iOS and Android. We also work with Xamarin, Ionic, and Flutter when a client's existing stack calls for them.

  • Yes. You get the copyright or license rights for the custom code we write for your project, and you can review our code ownership terms before the project begins.

  • No one can guarantee that. What we can do is check your idea against Apple's and Google Play's requirements up front, and run every app through testing and usability review before submission.
