TapeCalc: Feet-Inch Fraction

TapeCalc is the feet-inch-fraction calculator built for carpenters, framers, stair builders, finish carpenters and serious DIYers. Do your math the way you measure, without converting fractions to decimals in your head.

WORKS THE WAY YOU MEASURE
- Add, subtract, multiply and divide directly in feet, inches and fractions.
- Enter values with a tape-measure style keypad and one-tap fraction chips.
- Choose your precision: 1/8, 1/16, 1/32 or 1/64 inch.

SEE EVERY UNIT AT ONCE
- Instantly view feet-inch-fraction, decimal feet, decimal inches, yards, millimeters, centimeters and meters.
- Tap any value to copy it.

SPLIT A LENGTH IN SECONDS
- Divide a total into equal parts, or fit as many pieces of a given size as you can.
- Get each piece length plus the exact mark positions to measure from zero.
- Optional saw kerf so your cut list actually adds up.

LAY OUT STAIRS (NEW)
- Enter the total rise floor to floor, your max riser height and tread depth.
- Get the number of risers, each riser height, treads, total run, stair angle and the rise-by-run diagonal.
- Every step height is listed from the lower floor, so rounding never adds up on the stringer.
- Add risers with one tap for shorter, easier steps, and check the 2 risers + 1 tread rule of thumb.

MADE FOR THE JOB SITE
- Big, high-contrast display that reads well outdoors.
- History tape you can tap to reuse any result.
- Buy once. No subscription. No ads. Works completely offline, with nothing to sign in to and no data leaving your device.
