Workshop Measurement Log

Workshop Measurement Log is a purpose-built inspection tool for machinists, toolmakers and small workshops. Enter the specification, measure, record the reading: every value is checked against its tolerance with exact decimal arithmetic and kept as an inspection record on your device. PRECISION MEASUREMENT WORKSPACE - Part, feature, drawing reference, nominal size, tolerance, measured value, unit, instrument, date and notes in one form - Symmetric (±) or asymmetric tolerances (upper and lower deviations), zero tolerance where valid - Live PASS / FAIL while you type; limits are inclusive and nothing is rounded before the decision - Invalid specifications (upper deviation below lower) are refused MEASUREMENT DEVIATION VISUAL - A linear scale shows the lower limit, nominal, upper limit and the measured value in their true positions, with the deviation printed - Readable without colour: PASS and FAIL use different markers and every value is written out INSPECTIONS WITH REPEAT READINGS - Readings of the same part, feature and specification are grouped into one inspection - Chronological readings, PASS / FAIL counts, minimum, maximum, range and mean - "Add another reading" prefills the specification so only the measured value is typed - No process capability or uncertainty is implied from a handful of readings INSTRUMENTS - Keep your digital and vernier calipers, micrometers, dial indicators, bore, height and depth gauges with an identifier - Choose the instrument for each reading; see how many readings each one took - Optional calibration due date as a reminder. The app does not verify calibration or traceability. WORKSHOP DASHBOARD - PASS and FAIL totals, recent inspections, recent out-of-tolerance readings, most used instruments and calibration reminders REPORTS AND EXPORT - PDF inspection record per inspection: specification, every reading with instrument and time, summary - CSV export of all readings (RFC 4180, UTF-8), with feature and instrument columns UNITS - Millimetres or inches per record; equivalents shown with 1 in = 25.4 mm exactly; stored values are never altered PRIVATE AND OFFLINE - No account, no ads, no analytics. Everything stays on your device. FREE AND LIFETIME PRO Free: 10 records, full tolerance checking, inspections, instruments and the dashboard. Records are never hidden or deleted. Lifetime Pro (one purchase, no subscription): unlimited records, PDF inspection records and CSV export. Workshop Measurement Log compares the values you enter with the limits you enter. It is not a calibration tool and makes no claim of ISO, ASME or GD&T conformity.
