Hello everyone!
I wanted to share that I am developing
TV Timer+, an open-source Android TV application that gives users (parents;) control over their TV.
It bundles within it a local copy of ADB so it can send commands to control the TV, such as sleep, white-list applications and more.
The app is also released free on the Play store, for now the only feature is setting a sleep timer.
Hope you all have a great weekend :)
