Plumb
Plumb is a precision spirit level and inclinometer for iPhone that features three measurement modes — a horizontal bubble level, an angle finder with construction-standard presets, and a bullseye surface level — all powered by a spring-damper physics engine running at 60fps. The app includes real-time feedback through sound alerts, haptic vibration, a flashlight hold, and a glowing ring indicator so you know when you're level without even looking at the screen. An AR camera passthrough mode lets you see exactly what you're leveling through the phone, and a hand-off mode locks the app to the screen when lending your device to someone on a job site.
