iPhone
Now with TTC, pregnancy, and perimenopause modes, fertility treatment reminders, dark mode, and on-device pattern insights. Same privacy core.
Hush is a privacy-first menstrual cycle tracker that does one thing: keeps every byte of your data on your device. No account. No servers. No ads. No tracking SDKs. We literally cannot sell what we never collect.
WHAT'S INCLUDED (FREE)
• Period logging — start dates, end dates, optional notes
• Symptom logging — mood, energy, pain, plus quick-tap flags for cramps, bloating, headache, fatigue, tender chest, acne
• Phase detection — menstrual, follicular, ovulation, luteal
• Phase-aware ambient design that shifts color through your cycle
• Next period and ovulation forecast that refines as you log
• Custom user-defined symptom flags
• On-device symptom pattern engine — "Cramps tend to show up 2 days before your period in 5 of your last 6 cycles"
• Symptom pattern detection across cycles
• Calendar view with phase-colored history
• Light, dark, and system themes
LIFE-STAGE MODES
• Cycle tracking (default)
• TTC — emphasizes fertile window, adds BBT, ovulation tests, cervical fluid logging
• Pregnancy — gestational week tracker, due date, week-by-week development blurbs
• Postpartum — return-of-cycle tracking
• Perimenopause — widens cycle tolerance, hot flash logging, no false "overdue" alerts
FERTILITY TREATMENT SUPPORT (TTC mode)
• Custom medication reminders (you set name, dose, times — we fire the alarms)
• Dose log + injection site rotation tracker (helps avoid bruising)
• Trigger shot countdown
• Two-week-wait countdown
• Stim cycle day counter
• Never gives medical advice — your RE's protocol is yours; Hush is the reminder system + journal

NOT MEDICAL ADVICE
Hush is educational. It is not a contraceptive and not a fertility diagnostic. Predictions are statistical estimates based on what you log — accuracy improves with more cycles. Always talk to a qualified healthcare provider for medical decisions.
