An ideal circadian guide, everything I could possibly want to help me with sunrise/set, UVA, UVB, and much more!

100% recommend. Great app with all the needed info for living life with the circadian rhythm. So appreciated that it is free, love the timers to remind of the sunset etc. especially on cloudy days. Also, a big plus the great and personal support, quick and very helpful replies.

This app helps me optimize my day and get synced with the circadian rhythm wherever I am. I definitely recommend. Over time, I have used the alarms less. I don't need one to wake up anymore, yay! There are quite a few tech bugs. The app has randomly reset itself a few times and all of my alarms and settings have to be redone. Sometimes alarms go off randomly without me having turned them on, or they'll go off at the completely wrong time.

The app does not take DST into account in my location (Europe). All times are one hour off as of this morning πŸ™ˆ. Glad I didn't claim the various xx % off offers for an app that doesn't get something basic like this right. My Circadian (which has a very cluttered interface unfortunately) does get the times and time slots for sunrise, uva, uvb and sunset right, so I'm afraid I'll have to use this for the time being.

Worst app ever seen in my life always stop and circle at the location enter page and does not move forward after adding location in it manually due to their problem of auto location even though after following all correct steps .it has not been opening a single time. I just want to check it after it has come in the newspaper today about its owner and it's benefits, so I thought to check, but it doesn't open only and has proved that the newspaper apps printed are wrong as they never works
β˜…β˜…β˜†β˜†β˜† Santhosh R Β· Mar 24, 2025
I installed first time. Its taking much time to locate the location. Taking time to buffer. I tried in mobile data and also in Wi-Fi networks. So I exit from this app. Plz fix it. I am curious to know about this app.
β˜…β˜†β˜†β˜†β˜† Melissa Quinn Β· Apr 5, 2025
This app has quite a few bugs in the alarm portion of the app. When the alarm goes off to wake you up, and you hit "dismiss" it behaves like a snooze. The thing that caused me to uninstall was when it went off and the screen was completely blank, there was no way to turn the alarm off unless I uninstalled the app.
