Eyeball It: Measure Stuff

You already carry a level, a tape measure, a sound meter, a light meter, a vibration meter and a magnetometer. All in your pocket. This app just turns them on.

Eyeball It is a bunch of tools living on your phone just waiting for their day in the limelight. What day is that? Only time will tell, but as the saying goes, "the best tool is the one you have with you when you need it," someone said this surely.

Tools you get today:

How Loud? A real decibel meter. Reads your microphone, shows the level with a context phrase ("about like a vacuum cleaner") and a color zone bar. Tap to start; pegs a peak; saves the session. Calibrate against a known reference (premium) for better-than-eyeball accuracy.

How Level? A bubble level that auto-switches modes: lay your phone flat, you get a target scope. Stand it on edge, you get a classic tube level. Cross-axis-immune math means it stays accurate even when you're not. Calibrate per-edge to dial in your phone's bias (premium).

How Long? An AR ruler. Place two points in the camera view, get the distance. Tap-to-fine-tune lets you nudge a point without losing it. Snaps to detected planes for cleaner reads. Honest about its limits: without LiDAR, it's a smart estimate. With LiDAR (Pro devices), it's tight.

How Vibrating? A vibration meter. Set your phone on a washing machine, a railing, an idling engine, then hit record; it reads the accelerometer and shows how hard things are shaking, in g. A live seismograph scrolls while it listens, and Stop pegs the peak. Free recordings run 30 seconds; premium goes unlimited and adds a live frequency spectrum.

How Magnetic? A magnetometer turned metal detector. A live field reading up top, sonar rings that ping faster as you close in, and a tone that climbs with the field. Tap Zero to hunt what's actually nearby instead of your phone's own guts. Premium adds Find mode (a bearing arrow toward the source), a rolling field log with peaks marked, and a threshold alert that buzzes and beeps when the field jumps past your trip level.

How Bright? A light meter that reads your camera. Reflected mode measures the light bouncing off whatever you point at. Incident mode measures the light actually landing in the room, using a plain sheet of paper over the front lens as a diffuser. It looks silly and it's the honest way to do this on a phone, so it's free. Premium adds a light alert that buzzes when the room hits the level you picked, color temperature in Kelvin, and camera settings worked out from the reading.

The name is the low-bar brand promise. The tools all do their best given your phone's hardware. Sometimes we're real accurate, other times we're using some complex math to literally eyeball it. We'll tell you which is which, in plain language.

No account, no login, no tracking. The ads are non-personalized, so nobody's building a profile on you. Go all-tools and even the ads disappear. Permissions only when needed: microphone for How Loud?, camera for How Long? and How Bright?. How Level?, How Vibrating?, and How Magnetic? need nothing. Sensors are free.

More tools coming. We've got two more in development; you'll find out when they ship.
