Precision Bubble Level

Spirit Level for Phone & Watch

Free · Designed for iPad. Not verified for macOS.

Your phone is already the most precise level you own. Now it looks the part. 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.
