This is a very good app for learning Key Signature Theory. But unfortunately it has a bit of a drawback. In that the user needs to complete the question in the allotted time. The app would be 100% if the users could turn off the timer as this would allow the learners to work out the answers better. And aid in their learning. Other than that the only other thing is that is sometimes crashes, although that is very rare. Could you please give the users the option to turn the timer off. Cheers.

Hi, thank you for your detailed and honest feedback. We will take on board your suggestions to see if we can improve the app going forward. We haven't experienced any crashes when testing on our devices, however we will try and investigate to see why it might be crashing on your device. Thanks.

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 in a different way 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

Only gave the app 4 stars instead of 5 because and this is going to sound ironic there's no option to purchase the app and it is very commercial heavy. The advertisements are very irritating.
