You can customize your character, join guilds, challenge your friends and earn rewards for completing tasks and goals. You can also customize your own list of habits and goals, split tasks into subtasks and set deadlines. The app also allows you to track your progress with visual graphs and metrics. It's an easy and fun way to stay motivated and make sure you stay on track.
