LevelUP Tool

About

LevelUP puts ten essential carpentry and measuring tools in your pocket — no more juggling a bubble level, a tape measure, a calculator, and a notepad on the jobsite. Whether you're hanging a picture, framing a wall, building stairs, or squaring up a deck, LevelUP uses your iPhone's precision motion sensors to get you a fast, reliable reading, plus the calculators to turn that reading into a cut list. WHAT'S INSIDE • Bubble Level — lay your phone flat on any surface for an instant two-axis level reading, with a calibration option for imperfect surfaces. • Spirit Level — hold your phone on edge like a traditional torpedo level, for plumb or level readings that automatically detect your orientation. • Angle Finder — measure any surface angle instantly, with the complementary angle calculated for you. Zero-here and hold functions let you compare two non-level surfaces. • Plumb Bob — a protractor-style plumb line that reads out how far a post, jamb, or wall corner is from true vertical, with the same zero-here and hold functions as the Angle Finder. • Miter Cut — enter or measure a corner angle and get your saw's miter setting instantly, for both inside and outside corners. Includes a spring-angle reference table for crown molding. • Feet-Inch-Fraction Calculator — add, subtract, multiply, and divide construction measurements in feet, inches, and fractions, plus a decimal-to-fraction converter. • Stair Calculator — enter your total rise and get riser count, riser height, tread depth, stair angle, and total run, with built-in warnings if your numbers fall outside typical residential code. • Board Foot Lumber Calculator — calculate board feet and total cost from your lumber dimensions, with nominal size presets (2×4, 2×6, and more) that fill in actual dressed dimensions automatically. • 3-4-5 Square-Up — check any corner for square using the classic 3-4-5 triangle method, scalable to your project, plus a general right-triangle solver for any two known sides or angles. • Room Measure — walk off a room's length and width to estimate distance and area, with an accuracy range so you know how much to trust the number. Every calculator remembers your last inputs, so you can jump between tools without losing your place, and clean labeled diagrams make it easy to see exactly what's being measured. LevelUP is built for DIYers, contractors, woodworkers, and anyone who needs a fast, good-enough measurement without digging out a physical level or a calculator. It's a reference tool powered by your phone's sensors, not a certified or laser-grade instrument — always double-check critical or safety-related measurements with dedicated equipment.
