About this app

Two minutes a day shapes who you are in a year.
A habit app grounded in behavioral science — Atom.


▶ Who it's for

· You've lost count of how many times you've started over
· Checklist habit apps left you with nothing but guilt
· You read Atomic Habits and wanted to change your life
· You want to see, with your own eyes, that you're keeping going


▶ Atom. is built on the science of behavior change.

· Two-Minute Rule — BJ Fogg / James Clear
· Habits automate at a median of 66 days — Phillippa Lally, UCL (2010)
· Implementation Intention — Peter Gollwitzer (1999)
· Goal-Gradient Effect — Clark Hull / Kivetz et al. (2006)
· Never Miss Twice — James Clear

Reading the research isn't enough.
Atom. turns it into something you can actually use.


▶ Everything free

· Three action tiers
· A full-year tracking calendar
· Per-habit reminders
· Home screen widget (iOS / Android)


For people who'd rather change by design than by willpower.
