The short version

  • Each has a real cost: Clue clues stated policy on not sharing data with law enforcement without a valid legal process is the companys own published position and legal interpretation, not an independent guarantee, and it can still be compelled to comply with a legally binding request under EU or other applicable law.; 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.
  • They diverge on capability: Clue covers Cycle and symptom 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.

Clue

  • Clues stated policy on not sharing data with law enforcement without a valid legal process is the companys own published position and legal interpretation, not an independent guarantee, and it can still be compelled to comply with a legally binding request under EU or other applicable law.
  • Deeper cycle insights and predictions, the features most likely to justify tracking in the first place, are gated behind the Clue Plus subscription rather than fully free.
  • Being a smaller company than some competitors, Clue has less capital and legal resource to contest large-scale legal requests than a larger, better-funded rival might, despite its stated intent to do so.
  • Research partnerships using anonymised user data, while opt-in, still mean user-derived data can be used in ways beyond direct app functionality, and users should check current consent settings.
  • Cycle predictions rely on self-reported data and general population models, so accuracy for irregular cycles or specific medical conditions remains limited regardless of which app is used.

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

Clue: Does Clue share data with law enforcement?

Clue publishes a policy stating it does not share health data with law enforcement or public authorities without a legally binding request and states it will challenge requests it considers improper. This is the companys stated position; verify the current policy directly for specifics.

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.

Clue: Why does Clue emphasise being an EU company?

Clue operates under EU GDPR data protection rules and states this legal basis makes it harder for authorities outside the EU, including US authorities, to compel data disclosure than for a company based in the US.

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.

Clue: Is Clue free?

Core cycle tracking, logging and basic predictions are free. Deeper insights and extended predictions require Clue Plus.

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.
