Sophie: Cycle Intelligence
Sophie is a cycle tracking app that brings together Oura-connected biometrics, temperature-based fertility insights, and reflective wellness in one deeply personal experience.
Sophie is a cycle tracking app that brings together Oura-connected biometrics, temperature-based fertility insights, and reflective wellness in one deeply personal experience.
Uses temperature trend analysis and personalized cycle modeling to support temperature-based ovulation insights. With Oura Ring data, ovulation patterns can be interpreted using real temperature data.
Pulls your nightly temperature deviation, HRV, resting heart rate, sleep score, and readiness — all interpreted through the lens of where you are in your cycle.
Your natal chart mapped against real-time planetary transits. See how today's sky aspects your Sun, Moon, and Rising — and how it intersects with your hormonal phase.
An AI that knows your cycle day, hormone levels, biometrics, and birth chart. Ask her anything — she responds with data, not guesses.
Real-time moon phase with NASA-grade accuracy. See how lunar energy aligns with your cycle, set intentions by the new moon, release by the full.
Gentle, phase-aware nudges sent to your partner. Not what you're feeling — just what they can do. Empathy through biology.
Enter your last period start date. Sophie calculates your phase, estimates hormones, and starts building your pattern — no wearable required to begin.
Link your Oura Ring for real temperature, HRV, and sleep data. Sophie uses that data to support cycle awareness with temperature-informed interpretation rather than calendar-only guesses.
Enter your birth details. Sophie calculates your natal chart and overlays today's transits — showing you where cosmic weather meets your biological weather.
Sophie's temperature-based ovulation insights use the coverline method — 6 consecutive baseline temperatures followed by 3 elevated readings above the coverline + 0.1°C threshold. Combined with cycle history and a 5-day sperm survival window (Wilcox et al., 1995), it supports more personalized cycle interpretation over time.
