About this app

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. No accounts, no sign-in, no analytics.
• Beautiful in light and dark mode.
• Tablet-ready in portrait and landscape.
• No upsell, no subscriptions.

Free, supported by Google ads. You can opt out of personalized ads anytime.
