Private period, cycle, and fertility tracking app. No accounts. No cloud. No third-party trackers. Your most intimate data stays exactly where it belongs: on your iPhone. 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. WHY OVIFY IS DIFFERENT Most period apps send your intimate data to the cloud. Ovify doesn't. There are no servers, no analytics SDKs, and no hidden trackers. The app simply knows you because it lives where you do. WHAT YOU CAN TRACK - Periods & Cycles: Log your flow alongside 80+ symptoms and their severities. - Fertility Markers: Track Basal Body Temperature (BBT) with sustained-rise detection, plus cervical mucus and cervix position for the Symptothermal Method. - Daily Wellbeing: Log mood, energy, sleep, cravings, and sex. - Contraception: Get refill and replacement reminders for the pill, IUD, implant, injection, ring, or patch. 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!

Thoughts come. Thoughts move on. LetBe helps you step out of the rumination loop β€” not by pushing thoughts away, but by learning to let them move on. Based on principles of metacognitive therapy, translated into plain language. PARK YOUR THOUGHTS When a thought starts spinning, park it. It rises into your night sky as a glowing dot β€” not gone, just waiting. Once a day, at your worry time, you go through what's parked. By then, most of it has taken care of itself. CHECK YOUR WORRIES A worry is a prediction. LetBe remembers it and asks later: how did it actually turn out? Your evidence archive shows you, in black and white, how often fears come true. Usually: not at all. PRACTICE LETTING GO Guided audio exercises with a calm voice: place thoughts on leaves in a stream, let them drift away as clouds, or send them off on trains. TRAIN YOUR ATTENTION Attention Training (ATT) uses soundscapes to practice deciding where your listening goes β€” the core of the metacognitive method. PRIVATE, NO ACCOUNT No sign-up, no tracking, no ads. Your thoughts stay on your device. LETBE PLUS The method is free and stays free. A one-time purchase (no subscription) unlocks all soundscapes, additional exercises and the voice choice. Note: LetBe is a self-help tool and no substitute for therapy or treatment. If something weighs on you heavily, talk to a doctor or a counseling service.
