Naya - Period Tracker Calendar

Track your period, predict your cycle, and understand your body — privately.

Naya is a beautifully designed, privacy-first period tracker that helps you understand your body and take control of your cycle.

TRACK YOUR CYCLE Log your period with a single tap. Naya predicts your next period, ovulation day, and fertile window based on your unique cycle history. View everything on a color-coded calendar — pink for period, teal for fertile days, purple for ovulation.

LOG 100+ SYMPTOMS & MORE Track flow intensity, 15 moods, 19 symptoms, vaginal discharge, digestion, physical activity, sleep, water intake, sex & sex drive, and lifestyle factors. Naya organizes everything into easy-to-tap categories.

DISCOVER YOUR PATTERNS After 2-3 cycles, Naya automatically finds patterns in your data. See which symptoms repeat on the same cycle days, get predictions for what's coming, and discover how exercise, water, and sleep affect your wellbeing.

AI HEALTH ASSISTANT Chat with Naya's AI assistant — it knows your current cycle day, phase, and today's symptoms. Ask anything about your cycle, cramps, hormones, or wellness. Available in 26 languages. (Naya Plus)

READ HEALTH ARTICLES 48 evidence-based articles covering every cycle phase — from period self-care to ovulation signs, PMS tips to hormone balance. New insights delivered daily based on where you are in your cycle.
