CauseAndCorrelation Turns Hunches Into Daily Studies
A habit-and-outcome tracker that looks for statistical correlations across daily logs, including delayed effects.
Field notes
The service frames personal habit tracking as a small observational study: users define a possible cause and an outcome, then record each with a daily yes/no or 1–10 response. Its stated analysis looks beyond same-day movement by testing delayed effects, applies a minimum-data threshold, and corrects significance testing for multiple comparisons. The homepage also describes PDF export and an optional connection to Claude or another MCP-compatible assistant, though those capabilities are presented as site claims rather than demonstrated outputs.
