The 100 Day Challenge helps you work consistently toward your goals and build real habits. Instead of big leaps, it’s about small, daily steps that add up over 100 days and bring lasting change.
Key features
- Multiple challenges at once: Start and manage different 100-day challenges in parallel (e.g., reading, sports, learning, meditation).
- Daily completion: Mark your progress with just one tap – “Today done” keeps your streak alive.
- Visualization: See your progress at a glance: expanded view with 100 days, checked days in green with check marks.
- Motivating main screen: Personal greeting, overview of all active challenges, progress indicators, and quick selection.
- Icon selection per challenge: Choose a suitable icon for each challenge.
- Progress rewards: Visualize milestones and stay in the flow.
- Pro version (in-app purchase): Unlock all features, remove restrictions, and get additional personalization options.
Can I change the number of days?
No, the number of days is fixed at 100 days.
Can I check off days in the past?
If this option was selected when creating the challenge, days in the past can be checked off. This option cannot be changed later!
