Free vs Plus




Free (this page)
  • steps and sitting-removed calculation
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) break reminders
  • unlimited share images
  • share card without the 'Made with CortexLit' footer


Checkout isn't live yet, so Plus is unlocked here with a local code. The check runs in your browser and can be bypassed; it is a placeholder for a real payment link.






Free tier: 1 share image per result.






Commercial disclosure: optional paid Plus tier; all evidence, cautions and the main result are free. No affiliate links, no sponsors.







What this is based on


Every output names at least one verified PubMed source. Identifiers were verified on 2026-10-11 in an earlier batch and carried over into this build; they were not re-queried here, and no retraction database was checked. Verification was at abstract level.

Limits: This is arithmetic on your inputs, not a measurement. It does not estimate health effects; the sitting-mortality associations in the accelerometry study are observational.
