What is the 100 Day Challenge? 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. Why does it work? Because small, daily actions done consistently are more effective than sporadic motivation. 100 days is short enough to stick with and long enough to form real habits. Social accountability – use it to your advantage: Share the start of your challenge on social media or with friends. Post at the beginning and after important milestones – this creates gentle social pressure that motivates you to stick with it. Others know that you have started, and you don't want to break the streak. Privacy & Sync: All data is private and stored securely in your iCloud account. There are no central servers; your challenge data belongs only to you. Tips for maximum impact: • Choose clear, specific tasks (e.g., “read for 10 minutes” instead of “read more”). • Use multiple parallel challenges, but don't overload yourself – focus helps. • Check your streak regularly to avoid setbacks and maintain motivation. Upgrade to the full version: Unlock the full power: unlimited challenges and no restrictions on the number of days. Support & feedback: Do you have any ideas or need help? Write to us directly via the app or visit our support page (link in the app). Your feedback makes the challenge better.
