Practice Focus and Attention

Attention is measurable. Measure yours. Hone Focus is a daily attention practice built on twelve standard research tasks — the same paradigms attention science actually uses. Five minutes a day, and every round produces a real number. THE TWELVE DRILLS • Reaction time (PVT): wait, then tap — pure speed, remarkably sensitive to sleep. • Sustained response (SART): tap every digit except one; the habit is the trap. • Vigilance clock: catch the rare double jump as the minutes wear on. • Colour vs word (Stroop): the word argues with the ink — your interference cost, in milliseconds. • Flanker arrows: answer the middle arrow while its neighbours vote against it. • Side vs colour (Simon): where it appears argues with what it is. • Visual search: pop-out targets against needle-in-a-haystack scans. • Go / no-go: speed builds a habit; the rare shape asks you to brake it. • Stop signal: cancel an action already started — your brake, timed. • Task switching: the rule alternates, and it charges you every time. • Object tracking: hold several moving things in mind and find your ceiling. • Spot the change: a scene flickers; what you miss while looking straight at it. YOUR OWN NUMBERS Every drill records real measurements — median reaction time, lapses, interference cost, switch cost, stopping time, find times. The lessons teach with YOUR data: your vigilance decay curve, your interference profile, your reaction time after a short night. THE HONEST POSITION Practising these tasks makes you better at these tasks; the evidence that task practice transfers to everyday attention is weak, and this app will not pretend otherwise. What the numbers are for is noticing — what drains your attention, what protects it, and whether the change you made last month changed anything. The strategy lessons cover what has better evidence: environment design, implementation intentions, and sleep. Hone Focus does not diagnose, screen for, or assess any condition. PRIVATE BY DESIGN No account. No analytics. No tracking. Everything stays on your device; export or erase it all from Settings at any time. ADAPTIVE, GENERATED, FAIR Every round is generated fresh from a seed — nothing can be memorised — and each drill holds its own level, stepped from your own recent scores. Claiming something that was not there always costs: no drill can be beaten by tapping everything. SUBSCRIPTION Practice and lesson texts require a Hone Focus Pro subscription (monthly or yearly), with a free trial for eligible new subscribers. Your history and every measurement stay readable forever, subscription or not.
