Four production apps, 500,000+ combined downloads — from business tools to consumer apps, built with Flutter and cloud backends.
The four case studies below cover a wide range on purpose: a time tracking app with geo-fencing for companies, a charging and electricity price app built on AFIR-compliant DATEX II data, a native Android auto dialer, and Klaimo, a bike tracking app for consumers. Together these apps have passed 500,000 downloads. They all share one technical foundation — Flutter for a single iOS and Android codebase, with backends in Go, .NET or Node.js on Google Cloud Run.
Every project was carried from architecture to launch in-house: concept, UI, native integrations via Method Channels, backend and store release. For you that means short paths, direct answers, and 100% ownership of the code once the project is done.
Cloud-based time tracking with geo-fencing — built for teams spread across several sites and held to strict compliance rules.
Real-time transparency on charge points and electricity prices, built on AFIR-compliant DATEX II data.
An Android app that works through entire call lists on its own — wired straight into the operating system's telephony stack.
A bike-tracking app where every ride claims real territory on the map — with leaderboards, teams and a live map.
