TrueLevel Bubble Level vs Level Tool

TrueLevel turns your iPhone into a precise pocket spirit level and angle logger. Lay the phone flat on a shelf, a picture frame, a table leg, or a worktop and read how level it is two ways at once: a clear bubble that drifts toward the high side, and exact pitch and roll in degrees to one decimal place. Big monospaced readouts stay readable across the room. It is a straightforward utility tool — for hanging pictures, setting shelves, checking a tripod head, leveling a washing machine or a 3D-printer bed, or just settling an argument about whether the floor really slopes. WHAT YOU GET • 2D bubble level — a bullseye vial that turns green the moment you are within tolerance. • Pitch and roll readouts — single-axis vials and precise degree numbers for each axis. • One-tap zeroing — calibrate against any reference plane and measure relative tilt from it. • Angle log (Pro) — capture a reading, give it a label like "Top shelf", and keep a tidy history. • Adjustable tolerance — choose how close to flat counts as level, from 0.2° to 2.0°. The level, readouts, zeroing and tolerance are free. TrueLevel Pro, a one-time in-app purchase, unlocks saving readings to the angle log and its history. WORKS WITH WHAT YOU HAVE • Any iPhone with the standard motion sensors. PRIVATE BY DESIGN No account. No cloud. No ads, no tracking. Every reading stays on your device. Motion data is read only while the app is open and in front of you. A precise tool that fits in your pocket.

Turn your iPhone into the ultimate measuring toolkit. Nivelo packs 11 precision instruments into one app — no ads cluttering the screen, no unnecessary permissions, just tools that work. WHAT'S INSIDE - Bubble Level — Check any surface in seconds. Three modes: surface, 360-degree, and 3-in-1 view. - Angle Finder — Measure angles with real-time precision using your device sensors. - Protractor — Full on-screen protractor for quick angle readings. - 3D Angle Finder — Measure pitch, roll, and yaw simultaneously in three dimensions. - Laser Level — Project virtual laser lines through your camera for alignment on any wall. - Ruler — Accurate on-screen ruler in centimeters and inches. - Metal Detector — Use the magnetometer to detect metal objects nearby. - Inclinometer — Measure slopes and tilts with degree accuracy. - Compass — Full digital compass with cardinal directions and degree heading. - Plumb Line — Check vertical alignment with a simulated plumb bob. - Barometer — Monitor atmospheric pressure with the built-in altimeter sensor. BUILT FOR REAL WORK Haptic feedback lets you feel when a surface is level. Turn on the flashlight when measuring in dark spaces. Sound alerts confirm level status without looking at the screen. Calibrate sensors for accuracy on your specific device. One app instead of a toolbox full of separate downloads. Whether you're hanging a picture frame, checking a shelf, or working on a construction site — Nivelo has the right tool ready. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
