Ratings and reviews

This app is a ton of fun I enjoy it, The only thing that would make it better is if it could access our files or named folders so we can choose our own recorded sounds. This would allow us to be able to edit and play with our recorded sounds outside the app. Then I would go wild with it if we could! Edit : I'll move to 5 stars, I know this will be added, I will spend weeks playing around with sounds! if you can add a way to select a section in the sound easier I won't complain!

Old device, app doesn't stay open anymore (pixel4a). I understand that back compatibility is an issue while pushing apps to support newer systems but I would love to be able to roll back to the version I first installed and at least worked for me. Any option to be able to do this through different channels? P.S.: found the issue, it crashes when I start it with my Bluetooth headphones connected, no headphones = it just works.

Rip-off with almost all features to pay separately. instant delete.
