NaturalBloom is a hormone-free fertility-awareness app built around the Sensiplan sympto-thermal protocol — a well-studied natural family planning method that, when learned and used correctly, has been shown in published research to be a highly effective approach to family planning. Whether you're avoiding pregnancy, trying to conceive, or simply curious about your body, NaturalBloom helps you read the signals your cycle is already giving you. WHAT MAKES NATURALBLOOM DIFFERENT • Sensiplan-grade engine — three-over-six rule for temperature confirmation, peak-mucus rule cross-check, conservative fertile-window logic. Same rules a certified instructor would teach you. • Calm, clear, never alarming — no fear-based nudges, no "you're fertile!" red dots. Plain-language daily insights that explain what your body is doing and why. • Yours forever — one $19.99 purchase. No subscription. No ads. No upsells. Every future update to the iPhone app is included. Family Sharing is on, so your spouse gets it too. • Your data stays on your device — everything you log is stored in your phone's secure local storage. We don't run servers that hold your cycle data. We don't sell, share, or analyze it. We don't ship third-party advertising or analytics SDKs. WHAT YOU CAN TRACK • Basal body temperature — manual entry, Bluetooth thermometers (Easy@Home, Femometer, iThermo), or wearable temps from Apple Watch, Oura Ring, Whoop, Garmin, Fitbit, and Ultrahuman via Apple Health • Cervical mucus observations (Sensiplan categories) • Period flow and intermenstrual spotting • LH (ovulation) test results • Intimacy • Free-text notes for symptoms and life events WEARABLE-AWARE INSIGHTS If you wear an Apple Watch or Oura, NaturalBloom understands the quirks: • A nightly wrist-temperature deviation is calibrated to your oral baseline before being used as your BBT • Short-sleep nights (under 4 hours) flag the temperature as less reliable — Sensiplan recommends marking it "disturbed" • A heads-up that your luteal-phase HRV dip and resting heart-rate climb are progesterone at work, not poor recovery PERSONALISED, NOT GENERIC Every cycle, NaturalBloom learns your patterns: average length, ovulation day, luteal phase length, shortest and longest cycles. Daily insights reference your real numbers — "You ovulated 9 days ago. Your luteal phase typically runs 14 days, so your period is expected May 1." — never a horoscope. FOR EVERY GOAL • Avoid pregnancy: conservative fertile-window framing, double-confirmation cues • Conceive: peak-fertility highlighting, ovulation confirmation in plain English • Just understand my body: full body-literacy explanations of what's happening hormonally and what you might notice REFUND PROMISE NaturalBloom comes with a 60-day satisfaction promise. If it isn't right for you, email hello@naturalbloom.app and we'll endorse your refund request with Apple. IMPORTANT NaturalBloom is an educational tool. It is not a contraceptive, not a medical device, and does not provide medical advice. If you're using fertility awareness to avoid or achieve pregnancy, please learn the method thoroughly — ideally with a certified Sensiplan or sympto-thermal instructor — and talk to a clinician about decisions that affect your health.
