Most cycle apps guess. Sophie checks.

Sophie is a period tracker and cycle tracking app that reads your nightly body temperature from a smart ring or watch and looks for the shift that proves ovulation actually happened — then adjusts everything downstream to where you really are in your cycle, not where a calendar assumed you'd be.

TEMPERATURE-VERIFIED OVULATION
Connect an Oura Ring, Fitbit, or any wearable that syncs to Health Connect (Samsung Galaxy Watch, Galaxy Ring, Pixel Watch and more). Sophie reads overnight temperature, heart rate variability, and sleep to confirm ovulation from your body's own signals — the same basal-body-temperature principle used in fertility awareness, automated.

KNOW YOUR LUTEAL PHASE BEFORE IT KNOWS YOU
Luteal Watch counts down to your luteal phase so PMS days never ambush you again. Sophie gets smarter about your personal cycle every month — your ovulation day, your luteal length, your patterns.

SOPHIE, YOUR AI COMPANION
Chat or talk by voice with an AI that actually knows your cycle context — today's phase, last night's sleep and recovery, your energy. Daily readings, grounded guidance, zero jargon. No wearable? Sophie works fully from your logged periods.

PARTNER MODE
Invite your partner to a companion view that translates your cycle for them — what today feels like, how to show up, when to bring chocolate. You control exactly what's shared.

BODY MEETS COSMOS
Moon phases, your birth chart, tarot, and cycle-synced astrology — for the nights you want meaning with your data.

PRIVATE BY DESIGN
Your cycle data is never sold, never used for advertising, and never shared with data brokers. Delete your account and data any time, in the app.

Sophie is a wellness app for cycle awareness. It is not a medical device and does not provide contraception, diagnosis, or treatment.
