iPhone

Turn your iPhone into a precision spirit level. Measure tilt angles with real-time bubble visualization, recording, and calibration. Ideal for DIY and pro projects. Transform your iPhone into a professional-grade spirit level. Whether you're hanging picture frames, leveling furniture, or working on a construction project, Bubble Level gives you accurate tilt measurements right in your pocket. REAL-TIME BUBBLE DISPLAY A smooth, animated bubble moves naturally within a circular vial, just like a real spirit level. Color-coded feedback lets you know at a glance how level your surface is — green for level, yellow, orange, and red as tilt increases. PRECISE ANGLE MEASUREMENT View exact pitch, roll, and overall tilt angles in degrees. Know precisely how far off-level a surface is down to the decimal. RECORD & ANALYZE Start a recording session to track tilt changes over time. View minimum, maximum, and average tilt values to ensure consistent leveling across a surface. LIVE TILT CHART Watch a real-time graph of tilt history to see how angles change as you adjust. Great for fine-tuning alignment. CALIBRATION Calibrate to set any position as your zero reference point. Useful for measuring relative angles or compensating for case offsets. TILT SEVERITY GUIDE A built-in 12-level severity panel describes your current tilt state, from perfectly level to extreme angles, with clear color-coded indicators. Perfect for: • Hanging shelves, frames, and TVs • Leveling tables, desks, and appliances • Checking slopes and drainage angles • Construction and carpentry work • RV and camper leveling • Any project that needs to be level
