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.....) The only code/technologies I’m aware of are what I wrote (100% related to the visible functionally of the app) along with:
• Visual Studio (Apache Cordorva)
• Bootstrap (CSS)
• Bootstrap-switch (toggle switch)
• Vexflow (actual grand scale)
FYI, I can’t see how, but for any reason this software has an adverse effect on your device, I take no responsibility. You're on your own. ;)
