Looking for a Flo alternative? Compare Clue, Euki, Drip, Natural Cycles, Apple Cycle Tracking, Stardust and 28 by privacy, features and who each is best for.
Last reviewed
The short answer
The right Flo alternative depends on why you're leaving. For maximum privacy, Euki or Drip keep data on your phone with no account. For science-first tracking, Clue. For hormone-free birth control, Natural Cycles is the first app the FDA authorized for marketing as contraception, in 2018 (FDA decision). If you want more than tracking, with workouts and meals planned around each phase, 28. There are no ads in 28, and we don't sell your data.

Why women look for Flo alternatives
- Privacy.In 2021 Flo settled FTC charges that it shared users' health data with outside analytics and marketing firms (FTC final order, June 22, 2021). In 2025 Flo agreed to settle a US class action over the same kind of data sharing, without admitting wrongdoing (court notice, July 31, 2025, settlement agreement). At a hearing on October 29, 2026, the judge said he would grant final approval (Courthouse News). Mozilla's privacy review, published July 16, 2026, scored Flo 7 out of 10 (Mozilla Foundation).
- Ads and upsells in the free version.
- Wanting guidance on what to do in each phase, not just predictions.
