Bubble Level 3D: Inclinometer

Bubble Level 3D: Inclinometer is the professional precision alignment tool built for carpenters, DIY home renovators, construction workers, photographers, and decorators.

Say goodbye to unreliable spirit levels and shaky sensor readings. Powered by an ultra-lightweight Adaptive Kalman Filter engine (< 25 KB), Bubble Level 3D eliminates microscopic sensor jitter and hand tremors to deliver rock-solid, butter-smooth 0.00° accuracy on 60Hz and 120Hz displays.

REVOLUTIONARY KILLER FEATURES:

1. ONE-TAP CAMERA BUMP TARE (OFFSET CALIBRATION)

Modern smartphones have protruding camera lenses that cause a 1.5° to 3.0° mechanical incline when laid flat on surfaces. Our patent-pending Zero Tare feature lets you place your phone on any reference flat surface and neutralize camera bump tilt with a single tap. Offsets are saved permanently for future sessions.

2. TRI-MODE AUTO-GRAVITY SENSING

- 360° Bull's Eye Surface Level: Measure planar tilt across both pitch and roll axes simultaneously.

- Dual Tubular Inclinometer: Seamlessly auto-detects when standing on side or bottom edges to plumb walls, picture frames, shelves, and doors.

- AR Laser Horizon Level: Viewfinder camera overlay projecting an ultra-bright neon laser crosshair to align distant pictures and curtain rods without heavy ARCore libraries.

3. HANDS-FREE ACOUSTIC PITCH BEEPER

Working with dirty hands, holding heavy timber, or working on high ladders? Activate the acoustic radar mode. The app emits audible sound clicks that accelerate as you approach zero, snapping into a pure continuous 880 Hz tone and micro-haptic pulse at exact 0.00°. Level surfaces completely blind without looking at your screen!

4. PRO JOBSITE SLOPE CONVERTER

Instantly convert angles across 4 essential construction units:

- Decimal Degrees (0.00°)

- Percent Grade (%)

- Plumbing Pitch (inches per foot, 1/4" and 1/8" specs)

- Metric Run Slope (mm/meter)

Includes built-in code presets for ADA accessible ramps (1:12), drainage slopes, roofing rafters, and staircases.

5. 100% PRIVATE & BATTERY EFFICIENT

- Zero cloud uploads, zero account logins, zero tracking.

- Works 100% offline in full airplane mode.

- Optimized for low-end hardware: uses less than 65 MB RAM with instant startup.
