A clearer way to inspect your daily patterns.

Catalyst helps you upload or log daily habit data, choose inputs and outcomes, and look for Pearson correlations across same-day, next-day, and two-day lag windows.

It is built for quantified-self, habit-tracking, journaling, and personal analytics communities that want a quick way to explore questions like whether one daily behavior tends to move with a later mood, focus, energy, or productivity score.

The app is browser-only in v1: no accounts, no server, and no upload step beyond your own device.
