Cramming laws is no funChallenge accepted!
Our customer wanted to make learning employment law exciting, interactive and fun - without dusty deserts of paragraphs. The app needed to run smoothly on iOS & Android, offer a freemium model and integrate a stable payment system for premium users.
Our mission? A learning app that is addictive - but in a positive sense.
Learning that's fun
✔ Cross-platform & smooth - No bugs, no compromises, just play
✔ Freemium model - Start for free, premium features for power users. ✔ Gamer feeling instead of learning stress - Exciting duels, progression system & avatars.
✔ Payment system - In-app purchases neatly integrated into the app stores.
In short: Get knowledge without boredom.
Flutter, Firebase & a pinch of gamification.
💡 Flutter development - One codebase, two platforms, perfect performance.
🔥 Freemium model - Basic version for everyone, premium for the cracks.
🃏 Personalized flashcards - Deepen your knowledge on your own.
🎮 Turn-based duels - Learn in battle mode.
🎨 Animations & haptic feedback - Every interaction feels smooth.
⭐ Progression system & avatars - More motivation through visible successes.
With this combination, we have built a learning app that bucks - and imparts knowledge along the way.
Knowledge that lasts - and is fun.
LexQuiz! is not a dry learning platform, but a challenge with a real addictive factor. Players immerse themselves in exciting duels, make progress and have fun expanding their knowledge. Thanks to Flutter & Firebase, the whole thing runs butter-smoothly on all devices.

Strong, dynamic troops
Hafencity.dev has rebuilt my learning app for iOS and Android, and I’m completely satisfied with how the collaboration has gone. After that spontaneous first call with Hauke, I immediately felt confident. The offer was fair, and the implementation was quick and professional. Nico brought my project to life exactly as I had imagined, and I was kept fully transparent about the current status at every step. The collaboration was consistently constructive, pleasant, and—most importantly—on an equal footing. I especially appreciated that. I’m already looking forward to our next shared project! :)
I had a very informative exchange with the founder of the company. The fast processing of my request and the constant availability in case of queries convinced me.
We had Hafencity.dev in the running in a multi-stage selection process for the new development of our web app - and were impressed from the very first contact: fast, friendly, professional. Hauke and his team got to grips with our complex project very quickly, asked smart questions and thought through important aspects during the initial meeting. You can tell that genuine interest and a lot of experience on the customer side come together here. The way they work is structured, honest and efficient - no empty promises, but a clear focus on what makes technical sense. Even though we ultimately opted for a different implementation, Hafencity.dev remains on our radar as a top address.
In the field of media design, I not only create print media such as flyers and brochures, but also design websites, apps and various digital software. When it comes to implementation for my clients, hafencity.dev is always my first choice as a recommended agency. Compared to other, established agencies, this team really strives for modern implementations and doesn't charge exorbitant prices.
As a freelance software developer, I have had the opportunity to work with Marius on several occasions. I can recommend his service without a doubt! Marius' expertise and dedication to each project is unparalleled. He has the ability to quickly familiarize himself with new technologies and always delivers convincing solutions. I look forward to future projects with Marius and highly recommend him to anyone in need of quality software development.
