Hebrew Date Tracker
Shared Hebrew calendars for family & friends — birthdays, anniversaries, yahrzeits, and holidays.
New in Version 2
May 2026Version 2 is a ground-up redesign across all platforms. The big addition is shared groups that sync automatically — one person curates the family's dates and everyone else's app stays up to date, with no accounts and no sign-in. There's now a web view so relatives without the app can still see the calendar from a shared link, a propose-a-change workflow for members, and home- and lock-screen widgets on both iOS and Android.
About the App
Hebrew Date Tracker keeps the dates that matter — birthdays, anniversaries, yahrzeits, and holidays — on the Hebrew calendar, where they drift a little each Gregorian year. Instead of re-sharing a spreadsheet every year, one person curates a group and everyone else's app quietly stays in sync. Most families belong to a few groups at once: immediate family, in-laws, a yahrzeit circle. It's built to pass the "Aunt Sarah test" — install, paste a code, and see the family's dates without any help.
Key Features
Shared groups that sync
One curator edits the group; every member's app converges automatically. No accounts, no sign-in — just a short share code you can read aloud or paste.
Propose a change
Members can suggest adding, editing, or removing an event. The curator approves or tweaks it in one step — so the family's calendar stays accurate without a free-for-all.
Web view for everyone
Paste a shared link in any browser to see the group read-only — no app required. The apps register the link to open in-app when they're installed.
Home & lock-screen widgets
Keep the next upcoming dates on your home and lock screen, with dark-mode support and live refresh — on both iOS and Android.
Upcoming, Calendar & People
A redesigned four-tab layout: a countdown list of what's next, a month calendar, and a People view that groups every event by person — Hebrew and Gregorian dates side by side.
Private, local reminders
Notifications are scheduled on your device — with morning and erev-of timing, per-group overrides, and quiet hours. The server never reaches out to you.
Built for yahrzeits
Yahrzeits get their own treatment, including an "after sundown" option so the date lands correctly. Birthdays, anniversaries, weddings, and holidays each have their own type.
Anonymous by design
No accounts, no email, no phone number. Device identifiers are opaque, so the service never knows who you are — only the dates your family chooses to share.
Where to use it
iOS
iPhone and iPad, with a home- and lock-screen widget.
Android
Android 8.0 (API 26) or later, with a home-screen widget.
