Comments on Caffeine - Keep Screen On for Android

★★★★★ Jaap Thind · Jul 6, 2026

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

★★★★★ TR · Oct 26, 2026

It is one of my "go to" downloads. Is it sometimes not perfectly functioning on some devices? Yes, but if it works then it is a blessing. Just click, and you have your recipe open while baking without touching. Want a friend to read something on the phone? Click the button, and they can read without tapping every two seconds and accidentally going out the app. It just is a simple but helpful tool, and I will install it on my next phone again.

★★★★★ wraithlover · Jun 12, 2026

Does what it says it's supposed to, works great for long videos. Can actually keep the phone on all day.

★★☆☆☆ 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

★☆☆☆☆ Mike Jones · Feb 4, 2026

doesn't appear to work with Samsung note 9. Screen will still timeout

★☆☆☆☆ Peter Arthur · Mar 15, 2026

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

★☆☆☆☆ 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
