The short version

  • Only Calm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Annalise.ai the United States cleared indication covers roughly ten findings for triage and notification, far fewer than the model reports, so a buyer who evaluates the full multi-finding output and then contracts in the United States gets a much narrower cleared use.; Calm free tier is severely limited, with almost all content requiring payment
  • They diverge on capability: Annalise.ai covers Annalise Enterprise CXR, Calm covers Sleep Stories.
  • 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.

Annalise.ai

  • The United States cleared indication covers roughly ten findings for triage and notification, far fewer than the model reports, so a buyer who evaluates the full multi-finding output and then contracts in the United States gets a much narrower cleared use.
  • Triage AI reprioritises a worklist but does not change clinical decisions on its own, so departments that do not redesign how urgent studies are picked up see no measurable improvement in time to treatment.
  • Published validation is largely reader study evidence on detection of individual findings; prospective evidence of shorter time to treatment in routine emergency care is thin.
  • The Annalise brand is being migrated under the Harrison.ai name for the critical care offering, which creates ambiguity in multi-year contracts about what product name is actually being supported.
  • A high finding count raises the alert burden, and departments report that low prevalence findings generate false positives that erode radiologist trust unless the alerting thresholds are tuned locally.

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

Answered from the vendors’ own pages

Annalise.ai: How many findings are FDA cleared?

Around ten across chest X-ray and head CT, for triage and notification only. The model reports far more findings than that; the rest are not cleared in the United States.

Calm: What does Calm's free tier include?

The free plan includes 1 breathing exercise, Day 1 of programs, select Sleep Stories, and Scenes, plus the famous Daily Calm feature and bedtime stories. Most content is locked behind the paid tier.

Source
Annalise.ai: Is the European position different?

Yes. CE marking under the medical device regulation covers a broader decision support indication than the United States triage and notification clearances, so the same software is a different regulatory product depending on where you deploy it.

Calm: What is included in Calm Premium?

Calm Premium (all paid tiers are identical) includes The Daily Calm, Sleep Stories narrated by celebrities, exclusive music playlists, masterclasses taught by experts, Daily Move video lessons for stretching and mindful movement, and the entire content library.

Source
Annalise.ai: Does it diagnose?

No. In the United States it is a triage and notification device: it flags studies for earlier review, and the radiologist makes the diagnosis.

Calm: How much does Calm Premium cost?

Monthly subscription is $12.99/month, annual is $69.99-$79.99/year, Family Plan is $99.99/year (includes 1 Admin + 5 Members), and lifetime membership is available as a one-time payment.

Source
Annalise.ai: Is Annalise.ai becoming Harrison.ai?

The critical care offering is now marketed under the Harrison.ai name. Ask the vendor to name the contracted product explicitly before signing a multi-year deal.

Calm: Does Calm offer pricing for organizations or teams?

Yes. Calm offers organizational plans for groups of 5-300 people with per-seat pricing based on total 'covered lives.' Larger groups receive deeper discounts. Pricing is significantly reduced compared to individual subscriptions.

Source
Calm: Does Calm work offline?

Calm's app functions offline for already-downloaded content. Downloaded Sleep Stories, meditations, and Music programs can be accessed without an internet connection.
