Features

A focused tracker, deeply specified.

Ovify covers period and cycle tracking, the symptothermal method, an on-device AI assistant, charts and insights, and the quiet details that make daily use feel calm rather than demanding.

Cycle & period tracking

Log a period in two taps. Trust what it predicts.

Ovify starts from a sensible default (28-day cycle, 5-day period) and adapts to your history. Every prediction shows its uncertainty, and you can override anything by hand — past or future.

  • Two-tap period logging
  • Edit any cycle, any time
  • Confidence-aware predictions
  • Backed by your real history
  • Cycle and period length defaults
  • Customizable phase colors
Symptothermal method

BBT, mucus, and cervix — together on one chart.

Most apps treat BBT as a novelty. Ovify treats STM as a first-class workflow. Daily basal body temperature, with disturbed-reading flags, alongside cervical mucus and cervix position / firmness / opening — all charted, all editable, all yours.

  • BBT in °C or °F
  • Disturbed-reading flag
  • Cervical mucus observations
  • Cervix position & firmness
  • Intercourse marker (optional)
  • STM-aware insights
Ovify AI

An assistant that actually runs on your phone.

Ovify AI is built on Apple's on-device Foundation Models framework. It can read your cycle history, your STM chart, and your symptom log to answer real questions — and it does it without sending a single byte of that data off your device. No cloud round-trip, no training pipeline, no data broker.

  • Runs on Apple Intelligence hardware
  • Reads cycle, STM, symptoms locally
  • Logs entries on your behalf
  • Explains charts & predictions
  • Conversations stored on device
  • Falls back gracefully on older devices
Insights

Charts that read like sentences.

Cycle length over time, period length, ovulation timing, symptom frequency, BBT shifts — every chart in Ovify is paired with a plain-English summary that tells you what it actually shows. No gamification, no streak guilt baked into your hormones.

  • Cycle length trends
  • Period length variability
  • Symptom timelines
  • Fertile-window estimates
  • Phase explanations
  • Personal articles library
Daily logging

Symptoms, mood, contraception — without the forms.

Ovify tracks the things you actually want to remember: flow, mood, energy, sleep, cramps, headaches, libido, and anything else you'd like to add. Contraception too — pill, IUD, implant, injection, ring, or patch, with the right reminders for each.

  • Built-in and custom symptoms
  • Mood & energy tracking
  • Pill / IUD / implant tracking
  • Injection & device schedules
  • Smart daily reminders
  • Apple Calendar export
Private by default

Your data lives on your iPhone. Period.

  • Local-first storage
  • No analytics, no ad SDKs
  • Optional PIN & Face ID lock
  • JSON export, anytime
  • Apple Health (opt-in)
  • iOS-grade sandboxing

The small details we cared about.

Home Screen widgets

Glance at today's phase, days until your next period, or BBT-from-yesterday without opening the app.

Quick Actions

Long-press the icon to jump straight to "Log period" or "Log symptoms". Always one tap closer.

Education library

A growing set of grounded articles — STM, BBT charting, PCOS, endometriosis, PMDD, perimenopause, and more.

Apple Health

Optional, two-way. Read body temperature in, write cycle data out — only with explicit permission.

Notifications you control

Reminders for your period, contraception, or daily logging — at the hour you choose, or never.

Dark mode & custom colors

Pick an accent that's yours. Re-skin the calendar with your own phase colors. Light or dark, your call.

Ready when you are.
