Pemsi: Period & PMS Tracker

Pemsi is the period tracker that predicts hard days before they hit.

Most cycle apps only show what already happened. Pemsi forecasts what's coming — a 10-day PMS radar tells you which day this week will be the hardest, so you can move that meeting, swap that workout, and stop blaming yourself for "just feeling off."

★ PRIVACY-FIRST ★
Your cycle data is yours. By default everything lives on this device only — no account needed. Cloud sync is opt-in and end-to-end encrypted with a key derived from your password. Pemsi servers never see your plaintext data. We don't sell data. We don't run third-party ads. Health Connect access is opt-in and granular — you choose what to share.

★ WHO IT'S FOR ★
• Anyone tracking a menstrual cycle who wants better than basic
• People with PMS, PMDD, or unpredictable cycles
• Those trying to conceive (TTC) and want a clear ovulation window
• Anyone managing symptoms — endometriosis, PCOS, perimenopause
• People who like data + privacy

★ PERIOD TRACKING DONE RIGHT ★
Pemsi combines a clean cycle calendar with predictions you can actually act on. Period tracker, ovulation calculator, PMS forecaster, mood diary and AI cycle coach — all in one menstrual app, available in Ukrainian, Russian and English.

★ HOW TO START ★
1. Open Pemsi, tap the date of your last period
2. Tell us your average cycle length (or pick the default 28-day cycle)
3. The 10-day PMS radar, fertility window and ovulation forecast come alive immediately
4. Log your first symptom — every entry sharpens the prediction

The more you log, the smarter Pemsi gets. After three cycles the predictor switches from defaults to your real averages and regularity score.
