For some reason my 2 year old son loves to watch YouTube Kids and blast the volume on his iPad, but he also doesnt like to wear headphones. Frustratingly, even though you can limit headphone volume, there is no way to limit the actual speaker volume on most apple devices. This app is designed to work in the background to monitor volume levels and keep them at the level that you set. It also features a screen time alarm to notify you and your child when a certain amount of screen time has passed.
