## Description

**Bubble Level, Ruler** is a versatile Chrome extension featuring three smart measurement tools: a spirit level, plumb bob, and ruler. The spirit level offers audible leveling, multiple display modes, angle measurement with hold function, and simple calibration, supporting 12 languages for global usability. The plumb bob uses your device’s camera and accelerometer to measure tilt and angles digitally, including zoom, autofocus, reference lines, and flashlight features.

The built-in ruler allows precise length measurements with customizable units (cm or inches) and four distinct modes to suit different measuring needs. Whether installing appliances, hanging shelves, or measuring slopes, this toolset provides a functional, user-friendly solution on any smartphone or tablet.
