ux note 01: one tap. i've been designing and building my own product on the side. it's called tab, a clock for freelancers that turns your hours into an invoice your client actually pays. the rule i kept coming back to: starting the clock should take less effort than forgetting to. so it's one tap. no project picker, no forms, no "what are you working on?" pop-up. tap the client, the clock runs. tap again, it stops. everything else (notes, links to the work, the invoice) can wait until later. the start can't. it's free and in beta, so if you bill by the hour, i'd love to know what feels off. tabwork.app

one tap is the whole pitch honestly. most time trackers die because starting the timer feels like a chore

When batch sizes differ, calculate the overall minutes per unit from totals.

A fictional print-studio example: • Batch A takes 50 elapsed minutes for 10 completed orders: 5 minutes per order • Batch B takes 40 elapsed minutes for 20 completed orders: 2 minutes per order

Across both batches, that is 90 minutes for 30 orders, or 3 minutes per order. Averaging the two row rates gives 3.5, because it gives each batch equal weight despite the different order counts.

Before combining observations: • Keep the same start and finish boundary and definition of a completed unit • Check order mix, interruptions and other conditions; split unlike work into separate comparisons • Add elapsed minutes and completed units, then divide the totals • Retain the individual records so variation remains visible

The preview shows the actual Calculate and compare worksheet from the Process Time Study and Bottleneck Review Kit. Its Excel tracker uses total elapsed minutes divided by total units for the overall rate. The download also includes an editable Word packet, printable PDFs, a fictional completed example and Quick Start.

These are observed sample averages. They do not establish a standard labor rate, staffing requirement or employee performance rating.
