Frequently Asked Questions

The 21 Day Habit Challenge is a structured program designed to help you build new habits through consistent daily practice over 21 days. Research suggests that it takes approximately 21 days to form a new habit, making this timeframe ideal for establishing lasting behavioral changes.

To start a new challenge, enter your desired habit name and select a start date on the main page. Click 'Start Challenge' to begin tracking your progress. You can only have one active challenge at a time to maintain focus.

If you miss a day, your current streak will reset to zero. However, your overall completion percentage will still reflect all the days you've successfully completed. Don't get discouraged - consistency is key, but occasional setbacks are part of the journey.

Once a challenge is started, you cannot edit the habit name or start date to maintain the integrity of your tracking. However, you can delete your current challenge and start a new one if needed.
