Language learning App to become actually fluent

My brother Max and I founded abblino, abblino is an AI-based language learning app where users can learn languages through interactive dialogues in a stress-free and practical way. Personalized content and direct feedback make learning flexible, effective, and available anytime. A couple of days ago we launched or open beta on Android and are currently working on the iOS version. We would love to hear your opinions and feedback :)
