I love the WeMod mobile app, except one problem. There is no option to keep the screen awake while using it. It’s a pain to have to keep unlocking my phone to use it. Especially when I am at a critical moment in a game. I would’ve thought this would have been an obvious feature to include.

This has been suggested before. You can find them with the search tool.
For now, there are other apps in the store which stops the screen on your device from going idle.
