## What is Cutwise?

Cutwise is a measurement calculator built for people who work in inches and fractions all day. Three keypads — whole inches, numerator, and denominator . stay on screen at once, so entering 67-3/8" takes four taps, not a mode switch. Add 28-11/16", get exactly 96-1/16", and keep every step on a running history tape you can check back at the saw.

FRACTION CALCULATOR • Add, subtract, multiply, and divide inch-fraction measurements • Three always-visible keypads — no popup keyboard, no mode switching • Exact fraction math down to 1/64" — no rounding drift across chained cuts • Feet, millimeter, and centimeter readouts under every result • History tape: reuse, delete, and clear past calculations

SPIRIT LEVEL • Bubble level driven by your iPhone's motion sensors • Calibrate to any reference surface; the screen stays awake while you work • Slope, roof pitch, and plumb modes for layout and framing (Pro)

UNIT CONVERTER • Fraction-to-decimal in both directions, with reduced mixed-number results • Length free; area, volume, and angle conversions with Pro • Pulls your last calculator result in with one tap

MATERIAL CALCULATORS • Flooring and paint estimators, free • Drywall, concrete, stud layout, decking, and a cut-list optimizer (Pro) • Copy results or save them to projects so bids and cut lists stay together
