FAQ
Does Naia have ads?

Naia Pro offers two plans: Naia Pro Monthly at $12.99/month with no trial, and Naia Pro Yearly at $49.99/year with a 7-day free trial. Prices may vary by region.
How does Naia confirm ovulation?
Naia confirms ovulation by monitoring for a resting temperature shift that stays elevated for three days, or by analyzing positive PdG tests. It also uses LH test results to predict the fertile window.
Can I share my data with my doctor using Naia?
Yes, Naia allows you to generate a PDF report of your cycle history, confirmed ovulations, and luteal phase data. This report is formatted in a way that clinicians expect and can be easily shared from your phone.
How accurate is Naia compared to other apps?
Naia claims to be more accurate than calendar-based apps, which are correct only about four times in ten. Naia's predictions are built on confirmed ovulation data and your personal cycle patterns, not a generic day-14 rule.
What devices does Naia support?
Naia is supported on iPhone and iPod devices. It can also import resting temperature data automatically from Apple Watch via Apple Health.
How often is Naia updated?

Is my personal health data safe with Naia?
Naia prioritizes privacy by design. Your cycle data stays on your device, and no health information is sent to advertising or analytics networks. Deleting the app also deletes your data.
