ULA Period Tracker vs Dotted

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.  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.

Dotted is a calm, beautiful period and cycle tracker that keeps your data completely private — and is genuinely helpful in the moment. Private by design • Everything stays on your phone, encrypted. No account, no servers, no tracking. • No ads. No data selling. Free, always. • Move your data between phones with a passphrase-encrypted backup — nothing ever touches a server. Predictions that adapt to you • Learns your own rhythm from your last cycles — shown as honest ranges, never a fake exact day, and widening when your cycles vary. • Estimates ovulation from your own ovulation tests and cervical-mucus logs, so it doesn't just assume "day 14." • Personal symptom patterns: when cramps tend to hit, when PMS usually shows up. In the moment • A big cramp-relief button with quick, evidence-based relief and craving swaps. • Tap any day to log flow, pain, mood, energy, sleep and more — in one quick screen. • A cycle wheel, a phase-colored calendar, and home-screen widgets. Gentle reminders, your way • Phase changes, period due/late, PMS, fertile window, pill, daily check-in — each toggleable, scheduled locally on your device. Dotted's predictions are estimates, not contraception or medical advice.
