Bubble Level: Pro Spirit Level

Turn your smartphone into an industry-grade precision leveling toolkit! Traditional spirit levels, bulky laser levels, and plumb bobs are essential for accurate work—but you rarely have them on hand when you need them. TrueLevel: Digital Precision Tool delivers heavy-duty workshop accuracy right in your pocket. Engineered with an ultra-responsive industrial workshop interface, TrueLevel provides real-time sensor fusion with zero lag, ensuring your measurements are always 100% reliable. 🛠️ 6 SPECIALIZED PRECISION MODES • 2D Bullseye Surface Level: 360° circular spirit level with concentric calibrated rings and liquid refraction for tables, floors, countertops, and appliances. • 1D Horizontal Tubular Level (H): High-accuracy spirit vial along the bottom edge for wide shelving, timber, and framing. • 1D Vertical Plumb Level (V): Side-edge tubular vial that auto-orients to either side of your phone for door frames, posts, and vertical studs. • Smart Auto-Orientation: Seamlessly shifts between 2D, Horizontal, and Vertical levels using smart hysteresis without screen jitter or double-bubble ghosting. • AR Laser Camera Level (Laser): Projects an augmented-reality laser guideline and reticle over your live camera feed. Works in both Portrait and Landscape to align paintings, tiles, and fixtures across entire rooms. • Relative Angle Goniometer (Rel): Set a custom reference zero (Δ Relative Angle) to measure bevel cuts, roof pitches, or the exact angle between two surfaces. • Calibrated Edge Ruler (Ruler): Physical touch-and-drag dual scale calibrated to your device’s screen DPI. Measure in millimeters, centimeters, and 1/16th-inch imperial units with real-time cursor readouts. ⚙️ PROFESSIONAL CONTRACTOR FEATURES • Multiple Engineering Units: Instantly cycle between Degrees (°), Slope Percentage (%), Roof Pitch (in/ft), and Civil Grade (mm/m). • Acoustic Radar & Reverse Beep: Dual-audio feedback! Choose between an arrival chime or an intelligent proximity radar that beeps faster as you near 0.0°—perfect when measuring overhead or behind walls where you can’t see the screen. • Tactile Micro-Haptics: Feel a subtle vibration click the exact millisecond your tool hits dead level. • Measurement Lock: Freeze your current reading on screen with one tap to inspect or transfer numbers to your blueprint. • Independent 2-Axis Sensor Calibration: Calibrate out phone case bumps and camera bump angles on a known flat surface; reset to factory baseline anytime. • Integrated LED Worklight: Toggle your phone’s flashlight directly from the tool header to work inside dark cabinets and crawlspaces. • Global Language Support: Fully localized in 12 languages with native number formatting. 🏠 EVERYDAY & JOBSITE APPLICATIONS • Home & Decor: Hang pictures, floating shelves, flat-screen TVs, and mirrors with laser-sharp alignment. • Carpentry & Woodworking: Square cabinets, verify table saw bevels, assemble furniture, and true up stud walls. • Construction & Roofing: Calculate roof pitches, driveway slopes, drainage gradients, and foundation grades. • Photography & Video: Perfectly level tripods, match horizons, and set up overhead rig shots. • RV & Camping: Level your motorhome, caravan, or campervan in seconds before setting camp. 💎 GO PRO FOR LIFE (NO SUBSCRIPTIONS!)
