It is important to set your timezone for your goal setter to be accurate. As the goal setter resets at midnight every day, it is essential for it to be synced with your current location.
To change your timezone on iOS, tap the 'Profile' tab in the top right-hand corner, then select the ⚙️icon to access the Settings. You can then choose the correct timezone from the drop-down menu. Don't forget to tap Save!
Please note: to avoid losing your Streak, make sure you complete your Daily Goal for the current day before changing your time zone.
