What is a 100-day challenge?
Pick a small action such as studying, exercising, or reading and track it for 100 days. Focus on what you can do today instead of only looking at a distant result.
Three steps to get started
Choose an action you can finish even on a busy day, select Normal, Hard, or Extreme Mode, and set a reminder for the time you can actually act.
Why records support 100 days
A calendar shows your accumulated wins, while the timeline keeps photos and notes. Notifications and widgets add useful cues when memory and motivation are unreliable.
