Flo is the most downloaded period tracker in the world — but it's also one of the most criticized. In 2021 the FTC charged Flo Health with sharing users' sensitive health data with Facebook, Google, and other advertisers despite promising not to. Since then, Flo Premium has climbed to $79.99–99.99/year, with most useful features locked behind the paywall.
If you're looking for a Flo alternative that's actually free and actually private, here are your best options.
Best for: Irregular cycles, PCOS, perimenopause, TTC, and privacy-conscious users
WomensPal is completely free — no premium tier, no subscription, ever. It tracks your period, symptoms, mood, energy, BBT, and fertile window. Its standout feature is the Doctor's Report: an exportable cycle summary designed to be useful at medical appointments. GDPR-compliant with zero third-party data sharing.
Available on iOS and Android · app.womenspal.com
Best for: Science-backed tracking, research participants
Clue's free tier is genuinely usable for basic cycle tracking. The German company has strong GDPR compliance and has partnered with Oxford and Columbia for research. Clue Plus ($9.99/month) adds advanced features, but the free version covers core tracking without intrusive upsells.
Best for: Maximum privacy — no cloud, no account
Drip stores all data locally on your device. No account required, no server connection, no way for anyone to access your data. Built by the open-source community. Limited features compared to full-featured apps but unmatched for privacy.
Best for: Users in locations where health data privacy is a safety concern
Euki requires no account and keeps all data on your device. It also has a "fake data" feature that shows false information if someone else accesses your phone. Designed for users who need maximum privacy protection.
Best for: Birth control tracking alongside cycle tracking
Spot On is funded by Planned Parenthood and tracks both your cycle and your contraception. Free with no subscription, includes reminders for pill-taking, patch changes, and ring replacement.
Our recommendation: For most women — especially those with irregular cycles, PCOS, or who are trying to conceive — WomensPal offers the best combination of features, privacy, and zero cost. The Doctor's Report feature alone sets it apart from every other free option.
