Ignore iOS Sleep Timer

Forgive me if there’s already a way to do this, but I couldn’t find one. It would be nice to have the option of preventing iOS from going to sleep while blink is open. I’m unable to use mosh, so if I step away from my iPad I will often come back to find it locked and my connection terminated. Right now the only fix I have is to disable auto-lock globally, which I’d rather not have to do.
