Featuring a gorgeous obsidian glassmorphic theme, this application packs ten high-precision tools in one single pocket-sized toolbox. === 10 POWERFUL HARDWARE TOOLS IN ONE === 1. INTEGRATED TRIPLE-VIAL BUBBLE LEVEL Get all alignment indicators on a single screen! Features a horizontal vial, a vertical vial, and a circular bull's-eye level. Clear, fluid-simulated indicators respond instantly to every angle. 2. PLUMB BOB Check vertical alignments with ease. Use the plumb line tool to verify that posts, walls, or frames are perfectly upright. 3. TILT-COMPENSATED DIGITAL COMPASS Find your way with a smooth digital compass. Driven by hardware sensor fusion, it displays cardinal directions (North, East, South, West) alongside degree headings, even when tilted. 4. DUAL-AXIS CLINOMETER Measure slope, pitch, and roll in real-time. Features large, high-contrast digital readouts for absolute precision. 5. CALIPER RULER Measure small objects directly on your screen. Easy-to-adjust caliper lines allow you to get precise length readouts in inches or centimeters. 6. ELECTROMAGNETIC METAL DETECTOR Locate hidden pipes, wiring, or metals behind walls using your device's built-in magnetometer. Real-time microtesla readings show magnetic field strength. 7. SCREEN PROTRACTOR Measure angles of physical objects using your screen or camera overlay. Ideal for rapid construction sketching and DIY planning. 8. SCREEN TORCH (FLASHLIGHT) Light up dark workspaces with an ultra-bright screen flashlight. Features an adjustable brightness slider and variable frequency strobe mode. 9. CONSTRUCTION UNIT CONVERTER Instantly convert essential units of measurement: Length, Area, and Volume. Perfect for estimating lumber, flooring, or concrete volumes on site. 10. ALIGNMENT LOGBOOK & SHARING Capture what's on your viewport, type detailed notes, and stamp them onto the screenshot. Save records to your local logbook or share them with clients via the native share sheet. === KEY UTILITY FEATURES === • ACCURATE CALIBRATION: Establish a custom zero baseline on any reference surface. Easily reset to factory defaults. • AUDIO & HAPTIC ALIGNMENT: Align surfaces with your eyes closed! The app plays a looping beep and triggers a haptic pulse the moment you reach 0.0°. • SLEEK OBSIDIAN THEME: Beautiful dark glassmorphic design that saves battery and is easy on the eyes in low-light environments. • SENSOR FILTERING: Built-in low-pass noise filters dampen sensor fluctuations for smooth, stable bubble movement. Download Smart Bubble Level today and make every alignment and DIY task easier, faster, and more professional!
