Comments on Sleep Calculator for Android

★★★★★ KHROME_HDD · Jun 30, 2025

I've used this for years without reviewing, but now I have to say it has been the greatest sleep calculation app I've ever used! Thank you for allowing it to be free as well. ❤️

I don't use the sleep tracking option but the sleeping time calculator is so intuitive and great, you can really tell the effort that went into this app

★★★★☆ Dennis Magwaga · Jan 16, 2022

I don't want to track sleep but I like the bedtime and wake up calculator...if possible can remove the tracking

★☆☆☆☆ Benjamin LaLonde · Jan 19, 2024

Will not open anymore. Just stays on splash screen.

★☆☆☆☆ Ayush Roy · Aug 3, 2024

This app is just a Time waste. When I wake Up from sleep at that time only I press STOP, but it only records my sleep for 5 minutes. Even I have retried it for 2 - 3 times, but It does not work.

★★☆☆☆ Dalton Messmer · Feb 13, 2024

I want to rate this higher. This was one of the few free sleep tracking apps I found with a custom notes feature (i.e. "good day", "bad day", "ate out", "exercised", etc.) - and for that it's great. HOWEVER, there is still no "export to CSV" or similar option, even after a couple of years of requesting it from the dev, so I have years of data basically held hostage by this app. Also, there are occasional bugs which cause sleep tracking to end early and the alarm to never go off. Do not recommend.

★☆☆☆☆ Wilmandie Gelderbloem · May 29, 2022

It does not record that I wake up during the night. I have woken up, played with my phone and the app still said I slept through the night. Other apps actually shows the exact moment I wake up during the night.
