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.; Woebot Health the company withdrew its consumer app in June 2025 after concluding FDA marketing authorisation was not achievable at acceptable cost, which is a plain signal about both regulatory position and commercial durability.
  • They diverge on capability: Clue covers Cycle and symptom tracking, Woebot Health covers Scripted CBT dialogue.
  • 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.

Woebot Health

  • The company withdrew its consumer app in June 2025 after concluding FDA marketing authorisation was not achievable at acceptable cost, which is a plain signal about both regulatory position and commercial durability.
  • It is not an FDA cleared treatment for any indication, so it cannot be positioned to members as therapy and cannot substitute for a covered behavioural health benefit.
  • The scripted, non-generative design that makes it safe also makes it feel rigid next to current conversational AI, and engagement drops off quickly once users hit the edges of the script.
  • Published evidence is short-horizon symptom change in selected populations, mostly young adults, with little evidence of durable benefit or effect at whole-population scale.
  • With consumer distribution gone, the remaining business depends on a small number of payer and provider contracts, so a buyer should assume real vendor continuity risk over a multi-year term.

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.

Woebot Health: Is Woebot still available?

Not to consumers. The consumer app closed in June 2025. The company continues to offer the product to payers, providers and researchers.

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.

Woebot Health: Is it FDA cleared?

No. It held Breakthrough Device designation but never obtained marketing authorisation, and the founder cited the cost of that pathway as the reason for closing the consumer app.

Clue: Is Clue free?

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

Woebot Health: Is it generative AI?

Historically no. The dialogue is clinician-written and rule-based, a deliberate safety choice that limits how naturally it converses.

Woebot Health: What does the evidence show?

Randomised studies reported reduced depressive symptoms over short periods in selected populations, notably young adults. That is symptom change in a trial, not demonstrated population outcomes.
