What apps do you use to learn?

Hallo 👋 I've been learning German for 6 months now and my God the struggle is real, specifically with learning new vocab.

I decided to use my need and experience as a designer to create an app to efficiently learn vocab.

I'd like to validate this idea first, so my question to you is: Do you use apps to learn German? Which apps? Do you subscribe to a pro account or are they free?

🙏🙏
