Bubble Level

Turn your Android device into a professional high-precision Bubble Level & Spirit Level tool! Whether you are a professional carpenter, contractor, interior designer, engineer, or a DIY enthusiast hanging picture frames and aligning shelves, Bubble Level provides accurate angle measurement and surface levelling right in your pocket.

🌟 WHY CHOOSE BUBBLE LEVEL?

Built with advanced motion sensor fusion and real-time noise smoothing, Bubble Level delivers instantaneous, liquid-smooth pitch and roll telemetry with degree precision down to $\pm0.1^\circ$.

🚀 KEY FEATURES:

🎯 Dual-Axis 2D Bullseye Level & Tubular Spirit Levels: View pitch ($X$-axis) and roll ($Y$-axis) simultaneously on a 2D bullseye reticle dial or use the integrated top and right tubular edge levels for precise surface alignment.

⚖️ Relative Zero (Tare) Calibration: Instantly set any surface or inclined beam as your $0.0^\circ$ benchmark reference point. Measure relative angles easily on sloped roofs, ramps, and staircases.

🔊 Eyes-Free Acoustic Audio Feedback: Synthesizes a real-time pitch-modulated audio beep tone that rises in frequency as you approach exact level ($0^\circ$), allowing you to level objects in dark or hard-to-reach places without looking at your screen.

📳 Tactile Haptic Feedback: Triggers a crisp vibration pulse the moment your target reaches perfect level center.

📊 Complete Digital Telemetry Dashboard: Real-time numerical readouts for Pitch Angle ($X$), Roll Angle ($Y$), Slope Percentage (%), and Total Tilt Magnitude ($^\circ$).

❄️ Screen Lock / Hold Feature: Freeze current measurements on screen with a single tap to easily read values in tight spots or awkward angles.

⚙️ Customizable Precision & Damping: Choose precision tolerance modes ($\pm0.1^\circ, \pm0.2^\circ, \pm0.5^\circ, \pm1.0^\circ$) and adjust sensor response speed from instant to ultra-smooth damping.

🌙 OLED Dark Mode & Edge-to-Edge Design: Modern high-contrast dark telemetry theme with glowing emerald green level indicators that save battery life and provide maximum visibility under bright sunlight or low-light job sites.

📐 COMMON USES:

Carpentry & Construction: Level tables, workbenches, beams, framing, and cabinetry.

Home Decoration: Hang picture frames, wall mounts, mirrors, TVs, and shelves perfectly straight.

RVs & Camping: Level your RV, camper van, or trailer on uneven ground.

Photography & Videography: Align tripod heads and camera angles accurately.

Automotive & Engineering: Measure wheel camber, suspension tilt, and machine alignment.
