ToolTrunk is a beautiful, all-local toolkit that puts six precision instruments in your pocket. Whether you're hanging a picture, checking how loud the neighbors really are, or finding true north on a hike, ToolTrunk's tools are calibrated, fast, and respect your privacy. INSIDE THE TRUNK: • Level — A spirit level accurate to a tenth of a degree, with both bullseye and bar modes. Calibrate to any surface in one tap. • Compass — True heading with live calibration. Cardinal markings, fine ticks, and an honest accuracy badge so you know how much to trust the reading. • Sound Meter — A live decibel meter with peak, average, and a moving graph. Calibrated to common reference levels. • Flashlight — Torch, SOS strobe, and a full-brightness screen lantern. One tap on, one tap off. • Ruler — On-screen ruler in centimeters or inches. Calibrate once for your device, then measure anything. • Protractor — Measure angles precisely with both fixed and rotating modes. DESIGNED THE RIGHT WAY: • Every measurement happens on your device.
