Free Music Flash Cards play online

Flash Cards for music note memorization, that's it... No ads, no strings, no data collection, all free. I don't want my children seeing banner ads I may not approve of. Seriously, children educational apps should be free, no strings attached ... If you want to donate, please submit feedback containing info on your donation to a charity of your choice.

As the developer, I can say it contains no intentional malicious software (the truth is, if you use any third party tools you never truly know, there IS A MEASURE OF TRUST.....)
Edit: removed list of third party tools/API from google play feedback.

FYI, I cant see how, but for any reason this software has an adverse effect on your device, I take no responsibility. You're on your own. ;)
