This is not a to-do app. This is not a habits app. This is a checklist prompt app.

Build a list once. Run it whenever you need it. The way pilots and surgeons do, now in your pocket.

Not just a list.

Three things a to-do app won’t do for you.

Attention tone

A sound that keeps you on task.

Switch it on for a list and a soft tone plays while you run it. A little pressure, so you don’t drift off to another app. It stops the moment the last item is ticked.

Tap a tone to hear it

Research based

Built on studies, not hunches.

Checklists come from cockpits and operating rooms, where they are measured in lives. The app’s Manifesto tells that story, and its features name the research behind them.

Why a checklist?

  1. A checklist is not for people who can’t remember.
  2. It’s for people who don’t want to waste their thinking on remembering.
  3. Hand the remembering to ChecklistPro.
  4. Keep the thinking for things that matter. ReferenceForte, T. (2022). Building a second brain: A proven method to organize your digital life and unlock your creative potential. Atria Books.Capture what you need to remember in a trusted place outside your head, and your mind is free to think.
