## What is Plumbline Studio?

Plumbline Studio turns your iPhone into a focused measurement bench for carpenters, remodelers, inspectors, installers, and careful homeowners.

Use it when you need a level, plumb check, protractor, slope calculator, flatness scan, or trade math without opening a pile of separate utilities.

Core tools:
- Live bubble level with tap-to-zero calibration
- Dual-axis bullseye readout for cabinets, benches, shelves, and trim
- AR-style plumb planning view for checking vertical alignment
- Protractor and inclinometer with hold-to-lock angle capture
- Slope calculator with rise, run, degrees, percent grade, and ratio
- Stair, rafter, crown, board-foot, and cut-list helpers
- Flatness scan for spotting dips and bumps across a surface
- Project journal for saved measurements, notes, client names, and locations

Plumbline Studio is built around practical job flow. Take a reading, lock it, copy it, save it to a project, and keep moving. The interface is designed for repeated work in a shop, basement, garage, or jobsite, not for a one-time novelty measurement.

The app stores projects locally on your device. Camera and photo access are used only when you choose to attach a reference image to a measurement.
