FactTune is a decision journal. Log a decision, estimate the probability of each outcome, then come back later to record what actually happened. Over time, you'll see exactly where you overestimate, where you underestimate, and which areas of your life you predict most accurately.

How it works
Record any decision in under 30 seconds: what you're deciding, your predicted outcome, and how confident you are (10%–90%).
See your calibration score over time. Are you 70% confident when you're right 70% of the time? Most people aren't. FactTune shows you the gap.
Filter by life area — work, finance, relationships, health. Discover where your judgement is sharp and where it systematically drifts.
FactTune plots what you expected against what happened. Each row shows a confidence bucket — the orange bars show your predicted confidence and your actual hit rate. Gaps reveal systematic bias.
No streaks, no social feeds. Just a private log of your thinking and a clear mirror of how good your predictions really are.
