Her Days

Never be blindsided again. See her cycle at a glance, get a heads-up before the storm, and know the perfect day for flowers. Private — everything stays on your phone.

Her Days is the period calendar built for men.

Your wife, girlfriend, mom, sister — the women in your life run on cycles, and you keep finding out the hard way. Her Days puts them all on one calendar and tells you, day by day, what kind of day it is and what to do about it.

EVERY DAY HAS A HINT Open the calendar and every day shows a simple emoji hint for each person:

Comfort mode — her period. Warm tea, chocolate and patience. A small bouquet earns big points. Handle with care — PMS zone. Candy and compliments, skip the arguments. Romance peak — the best day for a date night and full romantic attention. Great mood — she's full of energy. Perfect for plans, adventures and surprises. Cozy support — chill evenings, comfort food and quiet attention.

Tap any day for a short, practical tip. No biology lecture — just what works.

TRACK EVERYONE WHO MATTERS Add as many people as you like — wife, girlfriend, mother, sister, friend. Each gets her own color, her own cycle settings and her own predictions. One glance at the month and you know exactly who needs flowers and who needs space. GET A HEADS-UP, NOT A SURPRISE Notifications arrive two days before a predicted period ("time to stock up on chocolate"), on day one, and on the best day for romance. You'll look thoughtful. You'll be prepared. Same thing.

IT LEARNS HER RHYTHM Tap "Period started today" when it happens and Her Days quietly adjusts its predictions to her real cycle instead of a textbook average. PRIVATE BY DESIGN No account. No cloud. No tracking. No data ever leaves your phone — there is nothing to leak and nobody to sell it to. Her cycle is her business; keeping up is yours.

BUILT FOR MEN Dark, clean, calendar-first. No pink dashboards, no fertility charts, no clutter. Just the information you need to be the guy who somehow always knows.

Note: predictions are estimates for everyday thoughtfulness, not medical or contraceptive advice.
