WomensPal vs Clue period tracker — a clear comparison of features, price, privacy, and which app is better for PCOS, TTC, or irregular cycles in 2026.
Clue is widely considered one of the more privacy-conscious period trackers on the market — it's GDPR-compliant and hasn't had the data controversies that plagued Flo. WomensPal is completely free and built for irregular cycles. Here's how they compare.
| Feature | WomensPal Free | Clue |
|---|---|---|
| Price | 100% free, always | Free tier + ~$49.99/yr Plus |
| Privacy / GDPR | No data selling, no ads | GDPR-compliant, Berlin HQ |
| PCOS / irregular cycles | Any cycle length, PCOS log | Better than most, but optimised for 21–35 days |
| BBT charting | Included free | Clue Plus only |
| Fertility / TTC tracking | Included free | Basic free, detailed on Plus |
| Symptom categories | Energy, mood, pain, skin, acne, hair | Extensive (30+ symptoms) |
| Cycle export | Yes, free | Plus only |
| Ads | None | None |
| Cycle education content | Built-in blog + articles | Clue Science — detailed |
| Subscription required for full access | No — everything free | Yes — key features behind paywall |
Clue's GDPR compliance and EU headquarters make it one of the more privacy-respecting options from major period apps. It doesn't run ads and has been transparent about data practices.
WomensPal also doesn't sell data or run ads — and its free model means there's no revenue pressure that could change this. Both are reasonable choices for privacy-conscious users.
Clue's free tier covers basic cycle tracking, but the features most women need — BBT charting, detailed fertility insights, cycle export, and full symptom history — are behind the Clue Plus subscription at around $50/year.
WomensPal includes all of these for free. There is no Plus tier. Nothing is locked.
Clue is better than Flo for irregular cycles — it doesn't rigidly assume 28 days and handles some variation. But its predictions still work best in the 21–35 day range. For PCOS cycles that extend to 40, 50, or 60+ days, WomensPal is the more reliable tracker because it learns from your actual data without assuming any "normal."
Want everything free · Have PCOS or very irregular cycles · Need BBT charting without paying · Want to export your data · Are TTC on a budget
Want EU data protection guarantees · Like detailed science content in-app · Are comfortable paying ~$50/year for full features · Have mostly regular cycles
Both are honest, privacy-respecting choices. The deciding factor is usually cost: if you want everything free, WomensPal is the answer. If you're willing to pay for a polished experience with deep science content, Clue Plus is worth considering.

Yes. Clue is headquartered in Berlin, Germany, and operates under EU GDPR. It has a strong privacy reputation relative to US-based period apps.
