KinScreen is the only app I have ever purchased. It just makes it easier to use my phone. Though it seems simple to turn a screen on and off, many phones don't do it well. KinScreen just works. Also it is very easy to use.
My lock screen would go black after 5 seconds. After I installed Kinscreen, I can make multiple attempts to unlock my phone without having to push the power button.
My screen would always go to sleep after 6 seconds of inactivity even though I had it set for 10 minutes. It would go to sleep starting up apps or while I was reading short paragraphs. Now it stays awake for as long as I need it to
I bought this app about 1 year ago and I've never had a problem with it. It does exactly what it says and it's function settings are perfect, not too complicated but detailed enough to do exactly what you want. Very well engineered.
Seems really good, works with Oreo, finally a great replacement for Screebl, and the basic settings are enough for me. I'd purchase it to support the developer if it supported the 'family library' option.
Ever since latest updates, screen will stay on even if phone is set down on a desk or table. APP IS NOT WORKING WELL, NOT WORKING THE WAY IT USED TO.
