You consistently misjudge how long things take and run late
Analogue clock, phone alarms, a notebook for time-tracking
Time blindness is a core ADHD trait — the brain genuinely cannot perceive time passing accurately. External time-making tools compensate for the internal clock that doesn't work reliably. Tracking actual task durations builds a realistic picture that overrides the brain's optimistic guessing.
Designed for adults. Many parents discover time blindness while supporting their ADHD child and realise they have it too.
One parent timed themselves getting ready in the morning for a week and discovered it took 45 minutes, not the 15 they'd always assumed. Setting their alarm 30 minutes earlier eliminated years of chronic lateness almost overnight.
