Ovulate
The everyday app to track your cycle with the sympto-thermal method, on your own or as a couple, with secure exchanges with your instructor — your data stored locally on your phone.
Discover the app →Ovulate is a cycle-tracking and symptothermal platform designed for women, couples and the professionals who support them — with one absolute requirement: your health data stays in Europe, under your control.
The everyday app to track your cycle with the sympto-thermal method, on your own or as a couple, with secure exchanges with your instructor — your data stored locally on your phone.
Discover the app →The first practice-management tool designed for the sympto-thermal method: patient records, scheduling, messaging, secure teleconsultation and payment links.
Discover Ovulate Pro →Ovulate was born from one conviction: cycle tracking should be neither a mental load carried by one person alone, nor a commodity monetised by foreign actors.
Cycle tracking concerns both partners. Ovulate enables simple, consent-based sharing of observations within the couple, so everyone can take part in the household's reproductive health.
Health data under Article 9 of the GDPR: Ovulate relies exclusively on HDS-certified European infrastructure, out of reach of extraterritorial legislation (Cloud Act, FISA).
Basal temperature, cervical mucus observation, peak day: Ovulate supports a recognised method with scientific rigour, and is preparing for connected temperature sensors.
Ovulate builds on the principles of the symptothermal method, a scientifically documented approach to cycle observation with decades of research behind it. Its implementation is validated by midwife expertise, guaranteeing the rigour of every reading rule.
Two independent indicators — temperature and cervical observation — confirm each other before any conclusion about your fertile window. This double check is what separates a rigorous observation method from a simple average-based calculation.
One app, to track your cycle with the sympto-thermal method wherever you are.
Your daily cycle companion: measurement entry, temperature charts, peak-day detection and educational content — stored locally on your device, with a secure link to your instructor and your partner if you wish.

A sovereign architecture designed from day one for the most sensitive data.
Beneath the apps, an architecture designed from day one for health-data protection — not bolted on afterwards.
A calendar app computes an average. Ovulate applies the sympto-thermal method: it cross-checks temperature against cervical observation, day after day, to reflect your actual cycle rather than a statistic.
Properly learned and applied, the sympto-thermal method is a scientifically documented observation method. Ovulate is a tracking and observation tool: it replaces neither learning the method nor the advice of a healthcare professional.
Only what you explicitly share, through a linking code you generate yourself. Sharing can be revoked at any time, from your side.
Yes. Full export of your data is a GDPR right, and a built-in feature of the app — your data is never locked in.
No. The app is local-first: your measurements stay on your phone. An account is only required for sharing features.
From simple cycle tracking to full sympto-thermal interpretation.
Indicative pricing, currently being tested.
