About SlopeGrade: 3D Inclinometer
SlopeGrade: 3D Inclinometer is a professional digital inclinometer, off-road vehicle pitch & roll gauge, and surface clinometer designed for off-road drivers, 4x4 overland enthusiasts, civil engineers, roofers, and carpenters. Engineered with low-pass sensor filtering, it transforms your smartphone into a rugged dashboard tilt-meter and precision grade measurement instrument.
KEY CAPABILITIES:
• DUAL 4x4 OFF-ROAD TILT METER: Real-time visual rear-view vehicle Roll angle and side-view Pitch angle gauges. Monitor your overland vehicle, truck, or SUV on steep trails, rock crawling, and hill descents.
• DYNAMIC ROLLOVER HAZARD WARNING: Color-coded safety zones (Green Safe <15°, Amber Caution 15°-25°, Flashing Red Danger >25°) with audible chime and haptic alert to prevent vehicle rollovers.
• SURFACE CLINOMETER & ARTIFICIAL HORIZON: Circular artificial horizon dial with 60° pitch ladder markings, ideal for roof pitch inspection, grading terrain, and leveling machinery.
• MULTI-UNIT READOUTS: Displays exact angles in Degrees (0.1°), Slope Grade Percentage (%), and Roof Pitch Ratio (X:12).
• ONE-TAP ZERO TARE: Calibrate against any angled vehicle dashboard or reference plane to measure relative slopes effortlessly.
• ANGLE HOLD & FREEZE: Lock the display with one touch to read measurements taken in awkward or low-visibility spots.
• NIGHT HUD OBSERVATION: High-contrast Dark Obsidian UI optimized for nighttime trail driving and outdoor work in bright sunlight.
• 100% OFFLINE & PRIVACY FIRST: Operates entirely client-side without internet. Zero sensitive permissions and zero battery drain when idle.
Tackle rugged trails and measure slopes with confidence using SlopeGrade: 3D Inclinometer!
