Naïa: Period & Cycle Tracker
Cycle, fertility & pregnancy
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Periods, ovulation, pregnancy: an app that adapts to your life, not the other way around. Your health data stays on your phone, and nothing is ever sold.
YOUR CYCLE, YOUR RHYTHM, YOUR STRENGTH
Your cycle isn't just dates. It's your energy, your moods, your skin, your sleep. Naïa helps you understand your body, without judgment, with an app that adapts to your life, not the other way around.
ONE APP, 8 LIFE STAGES
Choose your goal, Naïa does the rest:
• Track your cycle day by day
• Trying for a baby
• Follow your pregnancy week by week
• Get through the postpartum period
• Navigate your first periods
• Understand perimenopause
And because life isn't always smooth sailing, Naïa also offers gently designed spaces for when a pregnancy ends, whatever the reason. No judgment here. Just you, your body, and a space that understands you.
YOUR DATA STAYS WITH YOU
• Your health data is stored only on your phone
• Nothing is ever sold. No ads.
• No account, no email: download it and start
• Usage statistics are your call (and never any health data)
COMPLETE TRACKING, ESTIMATES THAT GET SHARPER
• Daily log: flow, 20 moods, 24 symptoms (cramps, fatigue, headache, acne…), energy, sleep, libido, weight, hydration
• Estimates of your next period and your fertile window
• The 4 phases of your cycle explained, with pointers for each one
• Calendar colored by phase and your cycle history
• Works with irregular cycles too: estimates get sharper with every cycle
TRYING FOR A BABY
• Estimate of your fertile window, cycle after cycle
• Basal body temperature chart, from your own readings
• Ovulation test log
PREGNANT?
• Tracking in weeks of amenorrhea, just like your doctor or midwife
• Due date calculated the French way
• Your baby's size and development week by week
• The French pregnancy follow-up exams, step by step
THE NAÏA COMMUNITY
• Question of the day: answer in one tap, anonymously, and see what others say
• Ask your question, anonymously: the most common ones will become articles
AND ALSO
• Daily pill reminder (21 days, 28 days or continuous)
• Library of articles recommended for your mode and your phase
• Guided Kegel exercises, dark mode, export of your data
NAÏA PREMIUM
The essentials stay available without a subscription, your history too. Premium adds your stats and trends, all in-depth articles and every level of Kegel exercises. Yearly subscription with a 7-day trial, or monthly, cancel anytime.
Naïa provides estimates based on the data you enter. The app is not a medical device, does not replace medical advice and must not be used as a method of contraception. If you have any questions about your health, talk to a healthcare professional.
