Great app, and it easily works on my pixel 10a. The screen stayed on, and I was able to add a shortcut in the control panel
★★★★★Mukul Singh· Mar 4, 2026
Works great!! Just a small request. If possible can you please add custom timeout? The maximum currently possible is only 1 hour or then infinite. I sometimes want to use it for 3–4 hours for reading purpose. So I don't want the screen to stay on for whole night in case I forget to turn it off manually.

This does exactly what I need it to do. I've been using it for years and it's been reliable.

First used on Xiaomi Mi6 official and custom roms, then Samsung A54 official rom. It's does its job as it should be. Using without problem in many years.

Doesn't prevent screen timing off. Reading the other reviews - it might be why my phone is turning itself back on during the night

doesn't appear to work with Samsung note 9. Screen will still timeout
★☆☆☆☆kiera healey-fort· Mar 2, 2026
Not helpful. I wanted to keep my screen on for work notifications without having sound on, but it didn't help. Even with turning off battery saving my screen still timed out and locked
★★☆☆☆Robert Townrow· Mar 1, 2026
Sadly this didn't appear to work on my Google Pixel 6a. I found Wakey works though. I tried setting the battery permission for Caffeine like it said, but it still didn't work. After several attempts I gave up and moved to Wakey instead. I appreciate the effort that went into this app - sorry it didn't work in my case
