Daychain
100-day chain

Can you get 1% better every day for 100 days?

The 1% Better challenge is 100 days with one habit. You do it every day in a size small enough for your worst day, and once a week you make one small change that makes it a little easier or a little better. The point is direction, not a number: a hundred links show the habit growing.

The rule

Do your chosen habit every day for 100 days, and once a week improve one small thing about it.

Miss a day?

A hundred days will include bad ones. Your weekly skip credit protects a missed day automatically, and a repair credit lets you pick the chain up if it still breaks. A broken day is never shamed in red; the next day is simply the day to continue.

How it works

  1. 1

    Choose one habit and shrink it

    Pick a habit you want and write a version you could do on your worst day. That version is your daily link.

  2. 2

    Mark it every day

    Each day you follow through, forge one link with a single tap and watch the chain grow.

  3. 3

    Improve one thing a week

    Once a week, change one detail: a clearer cue, a better place or a slightly bigger step. Then carry the chain to 100.
