The short version

  • Only Clue has a free tier, so it costs nothing to try first.
  • 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.; 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.
  • They diverge on capability: Clue covers Cycle and symptom 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.

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.

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

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.

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.

Clue: Is Clue free?

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