Exist: track everything

Track everything that matters to you with Exist, a personal analytics app that connects your data from services you already use to reveal patterns in your happiness, productivity, and activity levels.

Build a complete picture of your life by combining fitness trackers, health data, calendar events, work logs, and custom metrics all in one place. The app pulls activity from your phone and wearables, then analyzes what actually correlates with your wellbeing. Discover which habits boost your energy, what triggers your symptoms, which factors improve your sleep quality, and how different activities affect your mood and focus.

Track whatever resonates with you using custom tags and manual logging. Tag your days with events, people you spent time with, illness or pain symptoms, or anything else you want to monitor. Create numeric data points for quantities, durations, or subjective scales—rate your energy from 1 to 9, log your stress level, or measure sleep duration in hours. Rate your mood each night with optional reminders to build a clear record over time. The app then identifies which patterns matter most to you.

Exist connects seamlessly with the tools you already trust: Fitbit, Oura, Withings, Garmin, Strava, Apple Health, Health Connect, RescueTime, Todoist, GitHub, Toggl, Google Calendar, Apple Calendar, iCloud, Swarm by Foursquare, Instapaper, Mastodon, last.fm, and Apple Weather. Bring your existing activity data into one unified view without manual entry. The more data sources you connect, the richer the insights become.

Carry your data with you on your Android device and access all your metrics, dashboards, and insights wherever you go. See correlations between your sleep, exercise, work intensity, social time, and mood—then use those insights to make intentional changes to your daily habits.

Exist: track everything requires a paid account after a free 30-day trial. Subscriptions are US$6 per month. You'll need to create an account and provide payment information upfront, though you'll receive clear notice before your trial expires so you can choose whether to continue.
