The Rule

Three habits.
That's the limit.

Most habit apps let you add unlimited habits. We think that's why most people fail — you add twenty things, get overwhelmed, and give up entirely.

Trio enforces a hard limit of three habits. Not as a premium restriction — as a design philosophy. Pick three things that would genuinely change your life if you did them every day. Then do just those.
