Niio is a simple, private way to track your period, understand your body, and know what to expect — without the clutter. Log your period, symptoms, mood, energy, and sleep in seconds. Niio turns that into clear predictions and gentle reminders, so you're never caught off guard. WHAT NIIO TRACKS • Period dates and flow intensity • Fertile window and estimated ovulation • Symptoms — cramps, headaches, bloating, fatigue, and more • Mood and energy levels • Sleep quality • Private notes for anything else you want to remember PREDICTIONS YOU CAN TRUST Niio's predictions get smarter the more you log — starting from your own cycle history, not generic averages. Confidence labels are always shown, so you know whether an estimate is based on real data or still a first guess. GENTLE REMINDERS Get quiet, private notifications before your period and fertile window begin — never anything that gives away what they're for.

Your cycle data stays on your device. You can also lock the app with Face ID or your fingerprint for an extra layer of privacy.
