SmartZman
SmartZman keeps your smart devices in sync with zmanim, Shabbos, and Yom Tov — no weekly timer changes.
Fire devices off candle lighting, tzeis, and other zmanim — recalculated for you all year.
Set it once. SmartZman applies the right schedule automatically, every week and every Yom Tov.
Zmanim calculated for exactly where you are, with Israel and Chutz La'Aretz support.
Group devices by room and manage everything from a single app.
Schedules execute automatically, even with your phone off, with a full history you can check anytime.
Catches an accidental change to a scheduled device and quietly sets it back — unless you meant it.
