For Men: Period Tracker

A period tracker for the boyfriend. Track her menstrual cycle, see which phase she's in today, and know what the week asks of you. Works for more than one partner.

Most cycle apps are built for her. This one's built for you, to show up better.

For Men: Period Tracker is the partner cycle companion for boyfriends, husbands, and men who notice. Track her rhythm across all four phases: menstrual, follicular, ovulation, luteal, and get a real playbook for each week. No guessing whether it's a bad day or a bad week.

WHAT YOU GET

• Her cycle at a glance - current phase, day, and the next window • A playbook for every phase - what to do, what to skip, what to say • Multiple partners supported - each on her own cycle, sorted at a glance • Add her in seconds - name, icon, last period, done • 100% private - everything lives on your device • No account, no sign-up, no cloud, no tracking • Offline-first - works on the subway, on a flight, anywhere • Free. No ads, no paywalls, no upsell.

THE FOUR PHASES, TRANSLATED

MENSTRUAL - Bring warmth, patience, comfort. Skip the big asks. FOLLICULAR - She's rising. Green-light new plans, adventure, yes-energy. OVULATION - Peak connection window. Book the dinner. Say the thing. LUTEAL - Slow down with her. Fewer plans, more listening.

WHO IT'S FOR

• Boyfriends who want to stop guessing • Husbands who want to show up better • Long-distance partners tracking from afar • Anyone dating multiple people and losing track • Men who prefer their data on-device, not in a cloud

PRIVACY, BY DESIGN

No login. No email. No analytics. No ad SDKs. No cloud sync. Every partner, every date, every note lives in local storage on your iPhone. Delete the app and it's gone — really gone.

Built for men who notice.
