Exist is a personal analytics app that combines data from various services to help users understand and improve their lives.
Tools
Acquire Attribute Ownership
Tool to acquire ownership of attributes for the authenticated user. Allows your service to write data to these attributes. Use when you need to create or take ownership of attributes before writing data. Acquiring a templated attribute the user doesn't have yet will create this attribute and give you ownership.
Get Attributes With Values
Tool to retrieve attributes with their current values for the authenticated user. Use when you need both attribute metadata and their historical values. Results are limited to your read scopes.
Get Attribute Templates
Tool to retrieve a paged list of supported attribute templates. Use when you need to browse available templates before creating or updating data.
Get Averages
Tool to retrieve the most recent average values for each tracked attribute, with one set per week. Returns overall weekly averages plus daily breakdowns (Monday-Sunday). Use include_historical flag to retrieve historical average records.
Get Correlations
Retrieve a paginated list of correlations discovered between tracked attributes in the last week. Correlations reveal statistical relationships between different metrics (e.g., sleep duration vs mood). Filter by relationship strength, confidence level (statistical significance), or specific attributes. Returns correlation coefficients, p-values, and human-readable descriptions.
Get Insights
Tool to retrieve automatically-generated insights about patterns in tracked data for the authenticated user. Insights are observations about correlations, trends, and anomalies (e.g., "You walked more on days you slept well"). Use when analyzing user behavior patterns or displaying personalized feedback.
