Shabbos Clock

I’ve been using this app for many years. It’s excellent. Yes , the phone must be plugged in but so what? Nothing has ever happened to my I phone because it’s plugged in. Not for a day, two or three days. The volume is good and it’s loud enough to wake me on Shabbat.

Does the Job Well

I’ve had it a few years and use it virtually every Shabbos and Yontiff. It has its peculiarities but I know how to use it properly.

Didnt work

Not sure if being plugged in is a requirement but i had plenty of juice and it didnt ring. Should have an easier way test set up.

Don’t buy. It does not work

Does not work

Programs not functioning properly.

this program is not working properly
there is times when I delete some alarm time that I set up before
The alarm works anyway showing me the old set up
and when I’m looking on the main screen of the program it’s not there it’s been delete.
It’s usually happen when I set up some alarm for holidays (Shavuot) for example

if you can add on alarm repeat it would be a good thing for the pogrom
Thank you.

It also allows alarms to be set based on local sunrise and sunset times.

How do I set up alarms on Shabbos Clock?

You can set unlimited alarms with various options, including repeatable weekly patterns. Alarms can also be configured to trigger based on offsets from your local sunrise and sunset times. It's important to test your setup before Shabbat to ensure it functions correctly.
