The short version

  • Each has a real cost: Calm free tier is severely limited, with almost all content requiring payment; 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.
  • They diverge on capability: Calm covers Sleep Stories, Clue covers Cycle and symptom tracking.
  • 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.

Calm

  • Free tier is severely limited, with almost all content requiring payment
  • Only one meditation per day included in free tier (Daily Calm)
  • Annual pricing is among the highest in the meditation app category
  • Less extensive free content library compared to Insight Timer (which has 100,000+ free meditations)
  • Limited customization of meditation sessions; mostly follows Calm's curated content

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.
