Athena: Period & Cycle Tracker

Your cycle is nobody's business but yours.

Athena is a private period tracker and cycle tracker: no account, no cloud sync, no ads. Everything you log stays on your phone.

HONEST PREDICTIONS
• Period calendar, fertile window and ovulation predictions that learn your menstrual cycle, and admit uncertainty instead of inventing dates
• Irregular cycles, PCOS and long cycles handled without judgment
• A week-ahead view of what your cycle is likely to bring, learned from your own patterns

EVERY LIFE STAGE
• Trying to conceive? TTC mode with an ovulation calculator and DPO tracking
• On birth control? Pill reminder and BC modes that hide fertility guesswork you don't need
• Pregnancy mode, with endings handled gently
• Perimenopause and menopause tracking built on the STRAW+10 staging clinicians use

MORE THAN DATES
• Log symptoms, PMS, moods, flow and temperature
• Endometriosis and PCOS support: track what matters, see what returns each cycle
• Cycle guidance graded by evidence, with clinician red flags where they belong
• Wrist temperature from Health Connect can confirm ovulation, on your device
