4 stars: It's an overall great experience. The only thing I would recommend is instead of having a video of someone playing, make the sound of the piano sintetic, so when you put it to half speed you don't get that weird sound.
5 stars: BEST APP EVER You wanna know somthing? This is the best app ever! You can practice some songs for free (good songs for free), you can make the notes go slower if your not fast, you can even make it so it tells you if you did it right! Oh, and thank you flowkey for fur elise being...FREE!

I got frustrated by this and slowly lost the mood to play due to this setback. Please fix this, as I tested my mic multiple times and saw to it that it works fine.
3 stars: It's really good but only after one lesson. You have to pay for premium. In summary, the app has just one lesson for trial. That's all
5 stars: The bug with digital pianos causing the app to freeze when connected by midi over usb was fixed very quickly after being reported. Review updated to 5 stars as I really can't fault the app nor the customer service.
4 stars: Fantastic tool for learning piano! The app can be a bit iffy sometimes, but all in all it's great!
3 stars: My wife would give it 5 stars, but not me. If you are absolute beginner, ...
