Every score is traceable to its sources
No AI gimmicks, no buddy systems, no brain gardens. Four tools that change what you can see about your own brain.
A 0–100 balance from your habit logs: 50 is neutral, and every habit moves it by its research weight. Explore the model assumptions alongside 70 studies. This is an editorial estimate, not a measurement of dopamine.
Every logged habit plotted with its model contribution and a tap-through to available research. The only timeline that shows you why each spike matters.
Toggle a habit on or off to compare the model over the next 7 days. This explores assumptions, not your biological recovery.
Explore mechanisms, linked studies, evidence grades, and contradictory findings for 69 habits. Missing evidence is labelled.
Choose from 69 habits, each with a dopamine score backed by research. Healthy and harmful.
Mark what you did and didn't do. Takes 30 seconds. Your receptor gauge and timeline update in real time.
See your gauge climb as you cut spikes. Tap any habit for the science. Pro: project the next 7 days before you commit.
