This works well for keeping my phone from sleeping while waiting to catch pictures when the phone is setup in a tripod and on a charger. It also has a nice option that once you turn the phone off, is also turns off the app, so you don't have to go back to switch it off. Since it runs as a tile, it's easy to turn on. Simple and perfect. Running under Android 11, pixel 5

I use it as a toggle in my quick panel. One tap to activate & keep my screen on indefinitely, one tap to deactivate & return to my preferred regular setting of a 1 min screen timeout. I needed an app with a notification icon in the status bar because I have a tendency to forget it's activated. I also set my phone to auto deactivate it when I manually turn off the screen & lock it with the power button. No ads. No bugs. No battery drain. Exactly what I was looking for & works perfectly for me!

Works exactly as described. My company gave me a one minute timeout. Most of the time it's not an issue, becaue the apps I use can keep the screen open, or I don't need that much time not interacting with my phone. It is nice to have for other apps though, so I just set it to on when I need it, and have it turn off automatically when I don't use it. Good app!
