Shachar: Shabbos/Yom Tov Alarm

Shachar is a Jewish alarm clock, zmanim guide, and smart reminder app in one. Set a reliable alarm that rings even when your phone is locked or on silent, wake up gently, and start the day with the right davening times for exactly where you are.

Whether you need a loud morning alarm that actually gets you out of bed, a quiet wake before netz, or an alarm that works on Shabbos and Yom Tov without touching a thing, Shachar is built to fit a Jewish daily schedule.

Shabbos and Yom Tov, Hands-Free
- Shabbos alarms that ring for the length you choose and then shut off by themselves, with no snooze, no dismiss, and nothing to touch
- Yom Tov alarms on the real Hebrew calendar: every Yom Tov, or only the chagim you pick, from Rosh Hashanah and Yom Kippur to Sukkos, Shmini Atzeres and Simchas Torah, Pesach, and Shavuos
- Choose which days of the chag it rings on: first day, second day, Chol Hamoed, or every day of it
- Dates move with the Hebrew calendar each year on their own, and second days follow your diaspora or Israel setting
- Set it for Erev Shabbos or Shabbos morning, with candle-lighting reminders so Erev Shabbos never sneaks up on you

An Alarm Clock That Actually Wakes You
- Reliable alarms that ring even when your phone is locked or on silent, with a full-screen wake-up
- One-time, recurring, and multiple alarms with snooze
- Wake Sequence: a gradual alarm that rings a few times leading up to your set time, so waking feels easier
- Wake-up challenges: solve a quick math problem or take a few steps to turn the alarm off, so you really get out of bed
- Custom alarm sounds, including Sunrise, Gentle Chimes, Classic Bell, and a Shofar, or upload your own

Great for heavy sleepers who snooze through a normal alarm and want to be up in time for shacharis or minyan.

Zmanim for Your Exact Location
- Halachic times calculated for where you are: alos hashachar, netz (sunrise), sof zman kriyas Shema, sof zman tefilla, chatzos, mincha, shkia, and more
- The Hebrew date and Jewish calendar at a glance
- Set an alarm to wake before sunrise for davening k'vasikin in a couple of taps

Modeh Ani to Start the Day
- The Modeh Ani greets you on waking, shown in Hebrew, transliteration, and English

Smart Reminders and a Schedule That Thinks Ahead
- Create reminders for davening and tefillah, shiurim, appointments, and to-dos
- Make them by voice, just say what you need and Shachar sets it up
- The Schedule suggests the right reminders at the right time, like lighting Shabbos candles or waking before sunrise

Make It Yours
- Beautiful themes that apply instantly across the whole app: Midnight, Dawn, Parchment, Forest, Royal Plum, and Rose Quartz
- Home-screen widgets for your next alarm and upcoming reminders

Built by a Nonprofit
Shachar is made by TehillimForAll, a nonprofit. Every feature is available to everyone, with no paywall. If the app helps you and you want to support the work, there is an optional sponsorship, but it is never required.

Who It Is For
Shachar is for anyone who wants a dependable alarm clock and a warm way to keep Jewish times and reminders close. If you have been looking for a Jewish alarm clock app, a simple zmanim app for davening, a Shabbos alarm clock, an alarm that handles Yom Tov on its own, a gentle sunrise alarm, or an alarm with math to wake up, Shachar brings it together in one calm, easy place.

Wake up on time. Daven on time. Keep your day in order.

Recent changes:
Fixes alarms that could ring at times when nothing was scheduled.

Deleting a Shabbos or Yom Tov alarm now clears every ring in its wake-up sequence, instead of leaving some of them armed. This update also clears any stray alarms already left on your device.
