Feet, inches and fractions, worked out exactly. Choose rounding from 1/2 inch to 1/64 inch. Metric shown alongside. One payment. No ads, no subscription, no account.
Work out a feet, inches and fraction measurement exactly, the way it is written on a tape measure.
Type a measurement as you would say it: 10' 3.5" or 7' 11" 63/64. Add, subtract, multiply or divide it against another measurement. The result panel always shows three rows:
Exact, the result shown as the nearest 1/64 inch tape fraction, with ≈ when it falls between marks. Calculations keep the exact value.
Rounded, that same value at whichever precision you pick, 1/2" down to 1/64".
Metric, the equivalent in millimetres or metres, shown automatically alongside.
Change the rounding with a single tap. There is no menu to open and no setting to hunt for: six precision marks sit on screen the whole time, matching the marks on a tape measure.
The last 50 calculations are kept on the device so you can check back on a job without re-entering anything. Nothing is sent anywhere. The app has no account, no sign-in and no network connection of any kind.
One payment, that is all. Every operation works from the first launch. Nothing is held back behind a second purchase, a trial period or a subscription, and you are never asked to pay again for what you already own.
Built for woodworkers, joiners and anyone working from a tape measure on site or on the bench.
Ratings & Reviews

Now available in French, German, Italian, Spanish and Brazilian Portuguese. After you have used the app for a while, it may ask for a rating. The Exact line now shows the nearest 1/64 inch tape fraction with ≈ when the value falls between marks. Calculations still use the exact value.
