Can you keep going for 100 days straight?
The 100-Day Personal Chain is you, focused on a single habit of your choosing for 100 days. Each day you follow through adds a new link to your chain, and your only job is not to break it. After 100 days the habit stops being a struggle and becomes part of who you are.

The rule
Do your chosen habit every single day for 100 days and mark it in the app with one tap.
Miss a day?
100 days is a long road, and missing a day is completely normal. Your weekly skip credit protects that day automatically; if the chain still breaks, a repair credit lets you pick up where you left off. A broken day is never shamed in red — continuing is what matters.
