Plumbline Studio
Read full descriptionHide full description
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.

Verdict
The clearest difference is price: Rereminder at Free against Plumbline Studio's $0.99. Rereminder also leads on update cadence (every 3 days vs every 10 days). Plumbline Studio's advantage is in-app purchases (none vs 2) and iOS requirement (17.0 vs 26.0). On ads and device support there is nothing between them.
