Oh, thank you for your contributions! Mobile, we're planning a RN app (site is MobX/React), but we got our hands full at the moment (who wants a job?). TTS, I used to be of the opinion that TTS is something that should be kept far away from langauge learners. But, it got so damn good: https://azure.microsoft.com/en-us/services/cognitive-service... At least for many langauges. Didn't check the German much, interesting. For Hungarian, it screws up question intonation. But often it just seems completely human-like. I was concerned about the license for the audio recordings, and I assume recording quality could be mixed, but I'll take a more careful look.
