- They diverge on capability: Flo covers Cycle and ovulation tracking, UpToDate covers Clinical Evidence.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Flo
- Flo Health settled with the US FTC in 2021 over allegations it shared sensitive health data, including pregnancy and menstruation details, with Facebook, Google and other third parties despite telling users the data would stay private, a fact directly relevant to how much a user should trust current privacy claims without independently checking the published policy.
- Reproductive health data, including logged periods, fertility attempts and pregnancy status, has been the subject of law enforcement data requests in some jurisdictions following changes to reproductive rights law, and cloud-stored logs are a real category of exposure regardless of a vendors intentions.
- Anonymous Mode, the privacy feature introduced after the settlement, is a setting that must be checked and understood rather than assumed, and its exact scope and default status should be verified in the current privacy policy rather than taken from marketing copy.
- Free tier predictions rely on self-reported symptom data and general population models, so accuracy for irregular cycles or specific medical conditions is limited compared with clinical tracking.
- The subscription auto-renews and, like most mobile subscriptions, must be cancelled through app store account settings rather than inside the app itself.
UpToDate
- UpToDate does not publish subscription prices; the vendor (Wolters Kluwer) sorts buyers into separate individual, clinic-wide, and institutional subscription tracks and requires contacting the organization through its subscription-payment-options page rather than showing a rate for any of them.

Answered from the vendors’ own pages
Flo: What happened with the FTC in 2021?
The US FTC alleged Flo Health shared sensitive health data, including pregnancy and menstruation details, with third parties like Facebook and Google despite promising to keep it private. Flo settled without admitting liability, agreeing to obtain consent for future sharing and to an independent privacy review.
Flo: What is Anonymous Mode?
A privacy setting Flo states disconnects entered health data from an identifiable profile. Check the current app and privacy policy for whether it is on by default or must be turned on manually, since this affects what data is linked to your identity.
Flo: Is Flo free?
Core cycle tracking and predictions are free. Deeper personalised insights and expert content require Flo Premium.
