The short version

  • Only Calm has a free tier, so it costs nothing to try first.
  • Each has a real cost: Calm free tier is severely limited, with almost all content requiring payment; Therapixel european and American regulatory positions were established under different regimes, and under the EU Medical Device Regulation this class of diagnostic AI faces a higher classification and notified body scrutiny, so European buyers must verify the current MDR certificate and expiry rather than relying on a legacy CE reference.
  • They diverge on capability: Calm covers Sleep Stories, Therapixel covers MammoScreen 2D.
  • 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

Therapixel

  • European and American regulatory positions were established under different regimes, and under the EU Medical Device Regulation this class of diagnostic AI faces a higher classification and notified body scrutiny, so European buyers must verify the current MDR certificate and expiry rather than relying on a legacy CE reference.
  • MammoScreen does mammography only, so a hospital wanting AI across head CT, chest and breast needs several vendors and several PACS integrations, or an orchestration layer bought from someone else.
  • Therapixel is a small French company competing against Hologic and iCAD, which have incumbency inside the mammography reading workstation, so integration into an American breast centre is more work than it is for the workstation vendor own AI.
  • Detection performance is sensitive to the mammography unit vendor and acquisition protocol, so published results do not transfer between estates and each site needs local validation it must fund itself.
  • Whether AI can substitute for one of two human readers is a national workforce and liability question, not a product capability, so the labour saving that justifies the purchase in one country is not permitted in another.

Therapixel: What does the one to ten score mean?

It is a graded suspicion score per finding and per study, designed to be integrated alongside a radiologist BI-RADS assessment rather than treated as a positive or negative result.

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.
