Free vs Plus




Free (this page)
  • weekly split into long sessions and short pieces
  • guideline comparison
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) export of the whole week
  • 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.

Limits: This distributes a total you choose; it does not predict fitness outcomes. The meta-analysis found no fitness or blood pressure difference between accumulated and continuous exercise at similar volumes.
