Why time speeds up — and how denser memories slow it down

As you age, each year is a smaller fraction of the life you have already lived. Routines take over. Novelty fades. Days blur into weeks, and whole seasons vanish in hindsight. Psychologists call this age-based time compression: not a trick of the clock, but a consequence of how memory encodes experience.

Memory Density is a weekly measure of how many distinct, well-encoded moments your life contains. MemoryDensity helps you raise that score — interrupting autopilot with presence and novelty as time happens, and leaving richer retrieval handles so the past feels longer when you look back. Early access is for people who feel the acceleration and want tools to fight it.
