ChronoCheck

ChronoCheck is a mobile app that quantifies your subjective sense of time using quick, repeatable micro-tests (e.g., interval estimation, retrospective duration recall, and attention drift checks). It pairs these tests with lightweight context signals you already produce—calendar load, screen time, sleep, heart rate (optional via wearables), and location changes—to show what reliably speeds up or slows down your perceived time. The app outputs a “Time Dilation Profile” with weekly patterns, triggers (stress, boredom, flow, multitasking), and simple experiments to run (e.g., single-task blocks, novelty breaks, caffeine timing). This is not therapy and it won’t “fix your life”; it’s a measurement tool for people who want evidence about their own perception. The value is in trend tracking and actionable correlations, not one-off insights. Privacy-first: on-device scoring where possible, exportable data, and clear opt-ins.
