An open notebook for the quantifiable self. Log hundreds of metrics about your lifestyle, body, mind, and demography — then plot any variable against any other and see what relationships fall out of the data.
Fill in metrics across lifestyle, health, demographics, and personality. Edit any time. The catalog grows.
Scatter, bar, pie, line, histogram, or correlation heatmap. Choose any two metrics — across yourself or the entire community.
Get a Pearson r, a sample size, and an AI-written interpretation that always reminds you correlation ≠ causation.
