Zmanim Alarm

Android alarm clock

Wake on the Jewish clock.

Your day already runs on zmanim. Your alarm should too.

Zmanim Alarm sets your phone's own Google Clock alarms to the halachic times for wherever you are — alos, hanetz, sof zman krias shema, chatzos, plag, shkia. It recomputes them every night, so the times that shape your morning are the ones that ring.

How it works

Real times, computed fresh, set on your clock.

Alarms tied to zmanim

Anchor each alarm slot to a real halachic time instead of a fixed number — with your own offset, and your own ringtone per slot.

Calculated for your place

Times come from KosherJava, computed for your actual location and date. Set your spot once and the zmanim shift with the seasons on their own.

Refreshes itself nightly

A background job recomputes the day’s zmanim after midnight and re-arms each Google Clock alarm slot you’ve bound, then re-arms again after a reboot to keep the schedule current.

Bind any slot to any zman.

Choose from about fifteen zmanim and attach one to each alarm slot — each with its own offset and its own tone, so every wake-up rings on the time, and in the way, you want.
