Mobile App Studio
Lion Engine
We design and build mobile applications for iOS and Android — focused, polished, and shipped.
Current Work
prost!
A social app for beer lovers — built around real moments between real people. Share what you're drinking, clink glasses with friends, and track your beer journey.
Available on iOS and Android. Built with Flutter and Firebase, prost! delivers a native experience on both platforms from a single, high-quality codebase. The app includes a live social feed, map-based discovery, gamification, group features (Stammtisch), a beer passport, and real-time notifications.

What We Do
Full-stack mobile,
start to finish.
We cover the entire product lifecycle — from initial concept and UX design through engineering, backend infrastructure, and App Store submission.
Our technical foundation is Flutter for cross-platform development and Firebase for real-time backend services. We do not take shortcuts. Every screen, every animation, every data flow is considered.
Product Design
UX flows, visual design, prototyping. Interfaces that work without explanation.
iOS & Android Engineering
Flutter-native apps from a single codebase. Full performance, no compromises.
Backend & Real-time Data
Firebase Auth, Firestore, Cloud Functions, Storage, Push Notifications.
App Store Submission
We handle the full review process for both Apple App Store and Google Play.
About
A studio that ships, not just specifies.
Founded in Germany
Lion Engine is a German software studio. Our work is governed by German law, and we take data protection and user privacy seriously.
Focused by choice
We deliberately limit the number of projects we take on. Fewer clients means more attention, more quality, and better outcomes.
