Exist is a personal tracking app that combines data from services you already use with custom tags and mood data to help you find patterns and insights in your behavior. Exist tracks things like your activity, sleep, health, and social media use on top of tracking your productivity with integrations like Todoist.

Integrating Todoist with Exist can help you understand how your productivity is affected by other factors in your life. Exist will show you your count of tasks completed every day alongside your other numbers, and find correlations that show how your productivity can be affected by things like the weather, your mood, the music you listen to, how active you are, and more.
