Therblig is a stopwatch time study instrument built for industrial engineers — on the pick line, the packout wall, the assembly cell, anywhere work needs a standard. Named for the elemental motions of Frank and Lillian Gilbreth, Therblig runs the classic continuous method end to end: break the job into elements, time cycles on the floor, rate performance, apply allowances, and read a statistically defensible standard time — all on the device in your hand. THE CYCLE DIAL Every element becomes an arc on a live chronograph dial, sized by its observed mean. One revolution of the hand is one mean cycle, so you can see at a glance whether the operator is ahead of or behind pace. Lap with one thumb; the sequence advances itself. BUILT FOR REAL FLOORS • Continuous-method timing — the master clock never stops, so nothing is lost • Out-of-sequence work: tap any element pad and the reading is credited correctly • Foreign elements capture interruptions without polluting your data • Undo removes a mis-tap and rewinds the sequence • Large touch targets that work at arm's length STATISTICS YOU CAN DEFEND • Every reading plotted on a dot strip — outliers jump out; tap to exclude or restore • Sample-size check: n′ for ±5 percent precision at 95 percent confidence, per element • Coefficient of variation, standard deviation, and cycle-time trend per element • Coverage meter tells you plainly: sample sufficient, or keep timing FROM OBSERVED TIME TO STANDARD • Performance rating per element, by hand or with the built-in Westinghouse leveling guide (skill, effort, conditions, consistency) • PFD allowances applied study-wide • Standard time, standard minutes, and units per hour — recalculated live • Frequency handling for irregular elements (a pallet change once every ten cycles is 0.1) YOUR DATA, YOUR SPREADSHEET Export any study as a clean CSV — study header, full results table, and every raw reading — ready for Excel and your labor-management system. Everything stays on your device: no account, no sign-in, no data collection. FREE TO START, ONE PURCHASE FOREVER The free version includes two complete studies with every feature — enough to run a real study and trust the tool. Therblig Pro unlocks unlimited studies with a single one-time purchase. No subscription. Your stopwatch never stops working. Built by people who care about work measurement, for the engineers who set the standard.
