Leveler Plus vs Pulley & Belt calculator

Turn your iPhone into a precision digital spirit level. Leveler uses your device's built-in gyroscope and accelerometer to measure tilt angles in real time — perfect for construction, woodworking, DIY projects, and everyday tasks. BUBBLE LEVEL A realistic bubble moves within a circular level, just like a traditional spirit level. When the surface is perfectly level, the bubble snaps to center and glows green with haptic feedback confirmation. DIGITAL LEVEL View precise X and Y angle readings with large, easy-to-read numbers. Horizontal and vertical bar indicators give you a quick visual reference for alignment. KEY FEATURES • Real-time angle measurement updated 60 times per second • Bubble and digital display modes • Calibration system — set any surface as your zero reference • Save and organize unlimited angle readings with notes • Haptic feedback when level is achieved • Works in portrait and landscape orientation • Grid overlay for enhanced visual precision • Dark interface designed for job site visibility SAVE & ORGANIZE Tap to save any reading with automatic timestamps. Add custom names and notes to keep your measurements organized. Review, rename, or delete saved records anytime. CALIBRATE WITH CONFIDENCE One-tap calibration lets you set your current position as the zero reference point. Calibrate on a known level surface for maximum accuracy. Reset calibration anytime to return to factory defaults. BUILT FOR PROFESSIONALS & DIY Whether you're hanging picture frames, leveling furniture, checking floor slopes, aligning shelves, or working on a construction site — Leveler gives you the precision you need, right in your pocket.
