Tahor is a halacha-aware cycle tracker built for observant Jewish women. It handles the full taharas hamishpacha workflow — from period start through hefsek taharah, the seven clean days, and mikvah night — with the precision the halacha requires.
Your data never leaves your device. No accounts, no cloud sync, no servers. Everything is stored privately on your iPhone.

CALENDAR VIEW
Each day in the calendar is split at sunset — day onah on the left, night onah on the right. Cycle phases are color-coded (waiting period, hefsek, clean days, mikvah). Veset dots appear in the correct onah half. Tap any day to view details or edit entries.
ACCURATE ZMANIM
Tahor connects to HebCal to calculate sunset and nightfall times for your exact location. Bedikah reminders and mikvah night notifications are scheduled using real zmanim for your city — not a fixed clock time. Both Hebrew (3-star) and Rabbeinu Tam nightfall standards are supported.
SMART REMINDERS
Hefsek taharah available: morning reminder + 2 hours before sunset
Moch dachuk: optional reminder 1 hour before sunset
Day 7 bedikah: morning reminder, 1 hour before sunset, and urgent 20-minute reminder

All reminders use your local zmanim — no manual sunset entry needed

HEBREW CALENDAR
Full Hebrew date display throughout the app, including gematria notation on the calendar. Veset dates are shown with both Gregorian and Hebrew dates.
Tahor is designed as a personal reference tool. It does not replace consultation with a halachic authority (posek) for questions of halacha.
