What it does

Everything you need, nothing you don't.

Ovify covers the full picture of a cycle — from logging a period in two taps to charting basal body temperature to asking an on-device assistant about your patterns. Built around clarity, not engagement metrics.

Cycle & period tracking

Log a period in two taps. Edit any past cycle inline. Ovify learns from your data and predicts the next one — and shows you when it isn't sure.

Symptothermal method

Daily BBT, cervical mucus, and cervix observations on one clean chart. Designed with the rules of STM in mind, not bolted on.

Ovify AI — on device

Ask about your patterns, get explanations, or log entries by voice. Runs on Apple's on-device Foundation Models — your conversations never leave your phone.

Insights you can read

Cycle-length trends, symptom timelines, fertility windows, and phase explanations. Charts that show what's happening — not a daily score to chase.

Calendar & symptoms

A month view colored by phase. Tap any day to log mood, flow, energy, sleep, or anything else — your own custom symptoms supported.

Private by design

Everything stays on your iPhone. No accounts, no servers reading your data, no ad networks. Optional PIN or Face ID lock, full export anytime.

Your cycle, mapped

Built around the four phases — without the noise.

Ovify highlights where you are in your cycle today, what's coming next, and what the chart actually means. No "lucky days" theatrics, no fake certainty.

Phase 01

Menstrual

Days 1–5 typically. Logged with flow intensity, symptoms, and any notes.

Phase 02

Follicular

Energy rises as estrogen climbs. Ovify shows the window leading toward ovulation.

Phase 03

Ovulation

Predicted from cycle history, BBT shift, and mucus observations — together, not in isolation.

Phase 04

Luteal

Post-ovulation through next period. Symptom timeline helps you spot PMS or PMDD patterns.
