The short answer
What helps with ADHD time blindness?
Stop asking your brain to remember how long things “usually” take. Estimate one real task, time it, and keep the difference. A few honest repetitions create a personal planning multiplier you can use next time.
Why this works + common questions
Why compare estimated time with actual time?
Time management includes correctly estimating how long something will take. CHADD notes that people with ADHD can underestimate task duration, and its practical guidance recommends timers, smaller task steps, and deliberately estimating completion time. This tool turns that advice into one tiny loop instead of another spreadsheet you will lovingly make and never open again.

How the correction factor works
planning multiplier = actual duration ÷ estimated durationIf you guessed 15 minutes and the task took 30, the multiplier is 2×. Next time, a similar 20-minute guess deserves roughly 40 minutes on the calendar. It is personal planning data, not a score and definitely not a diagnosis.
ADHD time blindness tool questions
Is this an ADHD time blindness test?
No. It does not diagnose ADHD or measure a medical symptom. It is a practical task-duration tracker anyone can use.
What if I get interrupted?
Pause the timer for interruptions you would not normally include. Leave it running for ordinary context switching if that is part of how the task actually happens.
Why keep several results?
One task can be weird. A small history shows whether you regularly under- or overestimate and gives you a more useful recent multiplier.
Does StillAcre receive my tasks?
No. Task names and timing history are stored locally in your browser. Tool analytics record that a tool was used, not what you typed or how long your task took.
