Every calculation a builder needs. One app.
CutOnce replaces the scrap-paper math, the formula Googling, and the “I think that's right” guessing. Here's what's inside.
Fractions without the headache.
Construction runs on fractions. CutOnce makes fraction math fast:
- ✓Add, subtract, multiply, divide fractions and mixed numbers
- ✓Results in simplified fractions — no decimals to convert back
- ✓Handles 16ths, 32nds, and 64ths
- ✓Works with feet-inches-fractions format
Enter 3-5/8" + 2-3/16" and get 5-13/16". Done.
How much do you need? Exactly this much.
Stop over-ordering. Stop under-ordering. CutOnce calculates material quantities from your dimensions:
- ✓Concrete: Slabs, footings, columns, post holes — in cubic yards, ready for the batch plant

Feet to meters. Board feet to linear feet. Instantly.
Switch between imperial and metric. Convert area, volume, and length units. CutOnce speaks both languages — and every unit in between.
- ✓Feet / inches / fractions ↔ decimal feet ↔ meters
- ✓Square feet ↔ square meters
- ✓Cubic feet ↔ cubic yards ↔ cubic meters
- ✓Board feet ↔ linear feet (with dimensions)
Rise, run, and everything in between.
