About

Naia

Features
Read full description

Naia is a fertility and ovulation tracker for people actively trying to conceive. It narrows your fertile window to your two best days, and then does the thing no calendar can: it tells you afterwards whether ovulation actually happened. TIME IT RIGHT THIS MONTH Your fertile window is about six days long, and it moves. Naia reads your own signals, LH tests, waking temperature and cervical mucus, and puts a probability on today instead of painting a ten-day band. When your window opens you see your two best days, not a blob. THEN KNOW IT ACTUALLY HAPPENED An LH test says your body is getting ready. It never proves an egg was released. Naia watches for the temperature shift that only follows ovulation, or a positive PdG test, and then tells you plainly: ovulation confirmed, and the day it happened. If a cycle shows no confirming sign, Naia says that too, and after repeated cycles without signs it suggests a conversation with your doctor. It will never tell you that you did not ovulate; it reports what was and was not observed. YOUR TEMPERATURE IS THE PROOF A resting temperature that rises and stays up for three days is the classic confirmation signal. Naia charts it in real degrees on a real scale, alongside your LH results, so you can see the evidence, not just a verdict. Wrist temperature from Apple Watch imports automatically through Apple Health. MOST APPS GUESS. NAIA MEASURES. Cycle history alone lands the right day about four times in ten, because the first half of your cycle can vary by weeks. Every cycle you log teaches Naia your own pattern: your typical ovulation day, your measured luteal phase, how your timing moves. The predictions get sharper because they are built from confirmations, not from a day-14 rule. LOG IT ALL IN SECONDS One sheet for the whole day: period, intercourse, LH result, temperature, mucus. Ten seconds a day is enough. Manual LH entry works with any brand of test strip. SHOW YOUR DOCTOR REAL DATA One report collects your record: cycles recorded, which were confirmed, your measured luteal phase, and how complete the data is. It renders as a PDF on your phone and shares from there. It is written in the language a clinician expects. PRIVATE BY ARCHITECTURE Your cycle data stays on your device. No ads, no selling of personal data, and no health information is ever sent to advertising or analytics networks. Deleting the app deletes the data. SUBSCRIPTION Naia Pro unlocks every feature: your narrowed fertile window, ovulation confirmation, and the full cycle chart. Two plans: Naia Pro Yearly at $49.99/year with a 7-day free trial, and Naia Pro Monthly at $12.99/month with no trial. Prices may vary by region and are shown in the app before any charge. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed or cancelled in your Apple Account settings.
