Comments on Music Theory - Key Signatures for Android

★★★★★ Many years wanting to recognize the key on the music sheet immediately. With this app I learned it in 30 minutes.

★★★★★ I really like this application, it is very interesting to have an application with exercises about music theory. Just one suggestion : why don't you add the possibility to name the keys differently such as do re mi fa so la si do. I am French and using the international letters makes the application very complicated for me. Anyway, it is teaching me how to name the keys with their international name. Thank you for your great work and continue improving the application

★★★★★ I used this to brush up on theory. I have my students download it and use it in class.

★★☆☆☆ The adds are awful. Even for a free app. Shouty loud buy-me adds after every quiz. Just awful.

★★☆☆☆ The way this app would be useful is if it was a rapid fire time trial to see how quickly you can recall key signatures. Instead, it is a slow-paced quiz that makes you confirm after each answer that you want to move on to the next question.

★★☆☆☆ I think it would be far more helpful if this app gave you the key, and you put in the key signature as apposed to just giving the signature and asking the name.
