I purchased this app
Bugs and no audio

Quit all apps and restart the device. It happens when you open too many apps on the device. If the problem persist, send your device and OS details to support. Hope it helps.
Wildly inappropriate

The free app is provided as a demo to actually see the content and make a decision to buy. It is absolutely not advisable to practice on kids without purchasing.

Hi. The app is working fine. Some users email us and complain but at the end they find that their device is either muted or they had many apps running in the background. If that’s not your case you can contact us on the support email and we’d surely help you to troubleshoot the problem. The app is provided free as a demo. There is a cost involved in creating and managing the apps. The main idea is that if you find it useful, consider buying it. After the purchase you won’t have to deal with ads and other useful features will also be unlocked. Thanks for your time.
