Period Prophet: BBT & Cycle

Say goodbye to setting early alarms and fumbling with oral thermometers. Period Prophet turns your overnight sleeping wrist temperature into clear, actionable basal body temperature (BBT) insights. Wake up and instantly see where you are in your cycle—confirmed ovulation, period forecasts, and fertile days—without lifting a finger. KEY FEATURES: • Automatic Wrist Temp Tracking: Syncs seamlessly with your overnight wrist temperature to chart your personal biphasic curve. • Clear Ovulation Confirmation: Built on proven FAM / Sensiplan rules (6-low-3-high pattern) to verify true thermal shifts, not just calendar guesswork. • All-in-One Cycle Journal: Easily log flow, LH ovulation tests, intimacy, cervical mucus, and symptoms. Note fever, alcohol, or late nights to keep your charts accurate. • Wearable & Home Screen Ready: Quick-log directly from your watch; check current cycle phase on Home Screen widgets and Dynamic Island. • Phase-Based Healing: Soothing soundscapes, guided breathing, and gentle nutrition tips tailored to your follicular, luteal, and menstrual phases. • True On-Device Privacy: No sign-ups, no cloud accounts, and no ads. Your intimate health data stays securely on your iPhone, protected by Face ID. Who it’s for: • Anyone trying to conceive (TTC) who wants stress-free, automated BBT charting. • Anyone seeking a deeper, natural connection with their hormonal rhythm. • Health-conscious individuals who value total digital privacy over cloud subscriptions. Device Requirements: Requires a wrist-temperature-capable watch (Series 8 or later, Ultra) with Sleep Focus enabled. Manual temperature entry is also supported.
