About Exist
What is Exist?
Exist is a personal analytics tool that ties together data from your phone, fitness tracker, calendar, and other services – plus anything you manually enter – to help you understand how your habits and environment affect your mood, energy, productivity, and health. It solves the problem of scattered data by presenting everything in one place and running statistical correlations automatically.
Who is it for?
It’s for anyone who wants to optimise their daily life: biohackers, people tracking chronic conditions, productivity enthusiasts, and those curious about what makes a good day. It’s not for teams or companies – this is a strictly personal tracking tool.
Real use cases
Track whether morning workouts improve your energy, how social media time relates to stress, or what combination of sleep and caffeine correlates with back pain. Manually add symptoms, medications, or subjective ratings (1–9 scale) alongside automatic data like steps, sleep, and weather.
Key features
- Automatic data sync – Connect your phone, fitness tracker, calendar, and 20+ services to pull in health, activity, and productivity data without manual entry.
- Manual tracking – Create custom attributes (quantity, time, scale, percentage, or tags) to track anything your wearable can’t measure – like stress, caffeine, or symptoms.
- Correlation analysis – Discover relationships between behaviours, such as what makes you happiest or most productive, with statistical confirmation.
- Mood tracking – Log your daily mood and see which habits correlate with good days versus bad days.
- Daily insights & weekly summary – Get contextual insights each day and a weekly email digest of trends and changes.
- Cross-platform access – Use Exist on Android, iOS, and web, with data syncing across all devices.

What data can Exist track automatically?

What makes Exist different from a habit tracker?
Unlike simple habit trackers, Exist automatically finds correlations between your behaviours and outcomes (like mood or energy) using statistical analysis. It combines automatic and manual data to uncover relationships you might not notice.
Who is Exist best for?
It’s best for individuals who want a deeper understanding of how their daily habits, environment, and health metrics interact. Ideal for biohackers, people with chronic conditions, productivity nerds, and anyone curious about behaviour optimisation.
Is there a key limitation of Exist?
Yes, the biggest limitation is that it cannot predict or prescribe actions – it only shows correlations. Also, it requires consistent manual entry for any data your connected services don’t capture. There’s no team or family sharing.
