## What is Precision Bubble Level?

When your hands are full, your wrist has the answer.

PrecisionLevel is a digital spirit level for your iPhone and Apple Watch. Place either device on any surface — within a second, you know whether it's level. No squinting at a tiny bubble in a plastic tube.

YOUR WRIST, YOUR LEVEL
Hanging a shelf while holding it in place? Leveling a washing machine in a tight space? Glance at your watch instead of reaching for your phone. PrecisionLevel on Apple Watch is a standalone app — no phone required.

SUB-DEGREE ACCURACY
Hardware accelerometer and gyroscope with Butterworth filtering deliver smooth, precise readings. One-tap calibration compensates for your specific device's sensor quirks.

SEE IT AT A GLANCE
A responsive liquid bubble shows tilt in every direction. Directional arrows tell you which side is high. Color-coded feedback — green when level, amber when close, red when off. You never have to read a number unless you want to.

BUILT FOR THE JOB
• Multiple units: degrees, percent grade, mm/m, in/ft
• Hold & lock — freeze the reading, then move your device
• Dark & light themes — OLED-friendly dark mode or high-contrast light
• Configurable decimal precision
• Minimal battery usage

Free. No ads. No in-app purchases. Ever.
