  • They diverge on capability: Flo covers Cycle and ovulation tracking, Fullscript covers Protocol dispensing.
  • 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.

Fullscript

  • The practitioner sets their own margin on products they clinically recommend, which is a conflict of interest that some professional bodies and patients view badly, and the platform makes the arrangement easy rather than making it visible.
  • The account is free but the practice does not control pricing, catalogue, shipping cost or the patient discount, so the entire economics of the dispensary can be changed by the vendor without the practice having any lever.
  • Converting to a profit account requires personal identity verification, tax details and a bank account, and makes dispensary earnings the practitioner personal taxable income to report, which is administrative work no one warns about at signup.
  • Product availability and shipping are geographically limited, so practices outside the supported countries cannot use it at all and cross border patients will find items unavailable at checkout.
  • Patient refill schedules, plan history and a slice of practice revenue accumulate inside a platform the practice cannot export in a form another dispensary would accept, so switching later means asking every patient to re-enrol somewhere else.

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.

Fullscript: Is Fullscript really free for practitioners?

Yes, the account has no fee. Fullscript earns on the supplements sold through it, and a practitioner on a profit account also earns a margin on those sales.

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.

Fullscript: How do practitioners make money on it?

By converting to a profit dispensary and setting a margin. That requires tax information and a bank account, and the earnings are taxable income.

Flo: Is Flo free?

Core cycle tracking and predictions are free. Deeper personalised insights and expert content require Flo Premium.

Fullscript: What do patients pay?

No account fee, and a ten per cent discount on orders if the practitioner runs a no profit dispensary rather than taking a margin.

Fullscript: Is there an enterprise option?

Yes, quoted for health systems, adding central catalogue control, API EHR integration and cross site reporting.
