Clue is one of the most respected period trackers in the market — built by a woman-led team in Berlin with genuine scientific partnerships. But Clue Plus costs $9.99/month ($119/year), and some of its most useful features for women managing PCOS, perimenopause, or fertility tracking are locked behind that paywall. Here are the best Clue alternatives.
The free tier covers basic period prediction, moods, and symptoms — but for women who need more, the cost adds up.
Best for: Full-featured tracking without any subscription
WomensPal offers everything in Clue Plus and more — completely free. Cycle tracking, symptom logging, BBT charting, fertile window prediction, OPK tracking, and the unique Doctor's Report feature that exports your cycle data into a format designed for medical appointments. No account lock-in, GDPR-compliant, zero data selling.
Best for: Users who want a very polished UI
Flo has a beautiful interface and large community. Its free tier is more limited than Clue's and has a controversial privacy history (FTC settlement in 2021). Premium is $79-99/year. Not recommended if privacy is a concern.
Best for: FDA-cleared contraception
Natural Cycles uses basal body temperature as a contraceptive method and is the only FDA-cleared birth control app. At $99/year it's not cheaper than Clue Plus, but it's in a different category — a medical device for contraception rather than a cycle tracker.
Best for: Privacy-first users who want no cloud storage
Drip stores everything on your device with no server uploads. Covers period tracking, BBT, and cervical mucus in a clean open-source interface. No frills, but unmatched for privacy.
The bottom line: If you love Clue's science-backed approach but don't want to pay $119/year, WomensPal offers comparable — and in some cases better — features for free, including the Doctor's Report that Clue doesn't have at any price point.
