ULA Period Tracker

Your cycle should not be a product. Keep it yours with ULA. ULA is the period tracker built on one non-negotiable principle: everything stays on your device. No servers. No cloud. Your data belongs only to you, no one, not even us, can see your information. You've seen what happens when others do. Most period tracking apps have become something else entirely, wellness platforms, advertising engines, data brokers dressed in pink. They offer horoscopes, social feeds, and premium subscriptions, while your most sensitive health information quietly becomes their most valuable asset. Some have faced the legal consequences. Their users faced worse. ULA is the opposite of all that. One thing, done right. ULA tracks your cycle. That's it.Β  No social features. No ads. No upsells. No account required. Just an intelligent, private tool that learns your unique pattern, including considerations for irregularities like PCOS or PMS, and gives you predictions for your period, fertile windows, and ovulation. All on your iPhone. All offline. Track what actually matters: From bleeding intensity to ovulation pain, mood swings to fatigue, ULA gives you the depth to truly understand your body, without broadcasting it to anyone. Log symptoms, sexual activity, and cycle phases with precision. Edit past entries anytime. Your history is yours, no excuses. Nothing hidden. Nothing leaving your phone: ULA's prediction and business logic is open source. Audit it on GitHub. Verify the architecture yourself. We publish our math because we have nothing to hide and because you deserve to know exactly how your data is handled. Not a promise. Proof. ULA Period Tracker: Privacy. Period.

Ovify combines Symptothermal Method (STM) charting, predictions that sharpen with every log, contraception reminders, and a completely private AI assistant to help you understand your body without compromising your privacy.

The app simply knows you because it lives where you do.

OVIFY AI β€” YOUR PRIVATE HEALTH ASSISTANT Powered directly by Apple Intelligence on your device. Ask, "Why am I bloated this week?" or say, "Log bloating for yesterday." Ovify reads your data, answers your questions, and takes action. Your conversations and prompts never leave your iPhone. DEEP INSIGHTS & EXPORTS - Doctor-Ready PDF Reports: Instantly export your charts, cycle history, and symptom logs into a clean, comprehensive PDF to share directly with your healthcare provider. - Smarter Predictions: Track cycle length, period length, and variability with a confidence score that improves every time you log. - Phase-Aware Guidance: Daily insights tailored to exactly where you are in your cycle. - Consistency Heatmap: Keep your logging streak alive with visual tracking. - Worth-a-Closer-Look Flags: Ovify scans your last six months of logs for patterns worth discussing with your clinician (like very long/short cycles or unusual bleeding) and explicitly reassures you when everything looks normal, too. FULL SYMPTOTHERMAL METHOD Access a complete BBT graph, mucus and cervix tracking, 3-over-6 rule, Minus-8 rule, and Peak Day detection. Five bite-sized guides cover everything from getting started to accurately interpreting your chart. APPLE HEALTH SYNC Enjoy secure, two-way sync for menstrual flow and basal body temperature. Apple Health remains the system of record for exactly what you choose to share. WIDGETS Keep today’s cycle day and your contraception card right on your Home Screen for glanceable updates!
