Flo is the world's most downloaded period tracking app, with over 300 million registered users. It offers AI-powered cycle predictions, symptom tracking, pregnancy mode, perimenopause support, and a vast library of health content. It became Europe's first femtech unicorn in 2024 after a $200M+ funding round.
PairCare is a birth control pill reminder designed for couples. Unlike period trackers that treat contraception as a solo task, PairCare lets partners actively participate -- sending custom push notifications, checking pill status in real time, and sharing a calendar together.
Flo covers everything from periods to pregnancy to perimenopause. It's an all-in-one women's health platform built for individual use.
PairCare does one thing well: helping couples manage the daily pill together. Your partner gets notified, can send supportive messages, and sees the same calendar you do.
If you want comprehensive health tracking, Flo is a great choice. If you want your partner involved in your birth control routine, PairCare is built exactly for that.
In 2021, Flo settled with the FTC for sharing period and pregnancy data with Facebook and Google without user consent. A $56 million class action settlement was finalized in 2025. While Flo has since improved its privacy practices, the history remains a concern for many users.
PairCare does not sell or share user data with third parties. Your health data stays between you and your partner.
