Only for iPhone
Free · Designed for iPhone
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
