Comments on Clock Screensaver for Android

★★★★★ Keith Toy · Apr 1, 2026

This app is awesome! It's replaced my nightstand clock. I really like that it shows upcoming calendar events. It would be nice to have the local temperature displayed. That world be awesome!

★★★★★ Jun Kanzaki · Apr 21, 2026

Almost perfect ... just 1 request ... auto night mode (base on time is ok base on light sensor is good but extra permission maybe not happy for everyone) extra ... night mode is a little bit to dark ... how about if screen touch bright it up for few seconds

★★★★★ Madeleine Demers · Apr 6, 2026

This is a great screen saver clock just what I was looking for

★★★★★ Norman Dudman · Apr 23, 2026

Brilliant bedside clock. No adds, no crashes and very customizable providing you pay a very small amount for the pro version.

★★★★★ Andre P · May 22, 2026

I've now been using this great "bedside night-clock" app for a few years, and - combined with my alarm app running in the background - allows me the peace of mind for a sound sleep, but am gently awakened by the alarm at the correct times. I particularly like the analogue clock in addition to the day & date...perfect!

★☆☆☆☆ Another Human · Mar 23, 2026

Doesn't even seem to have a setting to show the numbers plus you have to pay 5 bucks to unlock settings. JOKE!

★☆☆☆☆ Joseph C · Mar 8, 2026

Rarely give 2 stars when I dislike an app but no ads is good. Outside of that, the app isn't good. Can't even remove the analog clock! Free clock apps exist that don't ask for money, give you colors, weather info, style choices, and they have no ads! Update: After learning its stuck on military time with no way to change it I took a star away. I don't pay for apps because I paid for them when I bought my device so im entitled to what I paid for with no restrictions and for free. Greed is pathetic!👎
