Feve is a serverless, zero-knowledge companion built to track ovulation, nourish fertility, and keep privacy—completely without cloud storage. Unlike data-mining apps, Feve requires no accounts or email signups, encrypting 100% of logs locally on the phone's chip. It stands out by combining an offline Bayesian ovulation algorithm with a library of 300+ cycle-synced recipes across global cuisines, using targeted nutrient tags to support a female preconception routine.
Hey Product Hunt! 👋
I’m Peter, the creator of Feve. I built this app first and foremost to truly support the journey to motherhood. Bringing a child into the world is one of life's most meaningful journeys, and I believe the women embarking on it deserve software that respects them, supports them, and treats data with sacred trust.
Unfortunately, mainstream period trackers routinely update terms of service to quietly monetize intimate biological data. I wanted to build a true alternative that lifts up a female preconception wellness routine without compromising digital sovereignty.
Feve is a deliberate act of digital independence. It operates on a mathematically zero-knowledge, 100% serverless architecture. There are no accounts, no email walls, and zero remote databases. Everything is encrypted and processed directly on the phone’s local hardware chip. Even if I am legally subpoenaed, it is physically impossible for me to access or view user data.
To support female's path, Feve combines an on-device, self-calibrating Bayesian ovulation algorithm with a massive culinary focus. The app features a library of over 300 cycle-synced recipes meticulously categorized across global cuisines—including Mediterranean, East Asian, Middle Eastern, South Asian, Southeast Asian, Latin American, Caribbean, and Nordic dishes. These meals are phase-synced to a changing hormonal calendar and enriched with targeted nutrient tags (like natural folate, iron, zinc, and magnesium) to organically build the body's nutritional foundations for pregnancy.
I believe in radical transparency, so we open-sourced the core engines. The codebase can be audited directly on GitHub:
• Algorithmic Predictor: github.com
• Secure Local Storage: github.com
Note for Android users: While the consumer brand lives permanently at https://feve.life, the official Google Play Store application listing is published under the technical package identifier string com.femia.health to keep the deployment independent from corporate cloud tracking frameworks.
I’d love to hear feedback, answer any architecture questions, or talk about offline-first app engineering. Thank you for checking Feve! 🥦🔐
