How a day felt while it happened, and how you remember it later. They disagree more than you think — and the second one makes your decisions. Two Selves measures the gap.
Free to track. iPhone. No ads, no data selling.
How it works
A quick read on today — one tap on a 0–10. How the moment actually feels, before memory edits it.
A week later, before the memory sets, rate that same day again — from memory, without working it out.
The difference is the part your mind quietly rewrites. Over weeks, it shows which way your memory bends.
The idea
A Nobel-winning idea from Daniel Kahneman: you have an experiencing self that lives each moment and forgets almost all of it, and a remembering self that keeps a story and makes your choices. Memory leans on the peaks and the ending and drops the long ordinary middle. So the days you spend on your phone can feel fine in the moment and read as empty later — and the run you dread can be the one your memory loves.
