Mental clarity track · coming soon

Daily IF tuned for sharp thinking.

For makers, students, and knowledge workers who want clean energy through the day.

What's coming

  • Daily 14:10 / 16:8 windows aimed at sustained focus
  • Caffeine + electrolyte timing tied to your wake-up
  • Stage-by-stage cognition notes (when ketones come online)
In the meantime
