Precision bubble level, angle finder & protractor - all in one app. Calibrate for accuracy. Free to start, Pro unlocks plumb mode & saved readings.
TrueLevel is the precision level tool, angle finder, and protractor your iPhone deserves. Use it as a bubble level to check any surface, an inclinometer to measure slope and pitch, or a spirit level for carpentry and DIY projects — all with a clean, beautifully crafted interface.
• BUBBLE LEVEL
Place your iPhone on any surface to instantly see if it's level. The dual-axis bubble responds in real time with smooth animations and precise degree readouts.
• ANGLE FINDER & PROTRACTOR
Measure any angle with a full 360° protractor display. Hold your device against a surface and read the exact angle — perfect for cutting, framing, or checking slope.
• PLUMB MODE (Pro)
Check vertical alignment with a dedicated plumb bob display. Ideal for door frames, fences, and wall installations.
• SAVE & REVIEW READINGS (Pro)
Lock any reading and save it for later. Review your measurement history and never lose an important reading again.
• PRECISION CALIBRATION
Calibrate TrueLevel to your device for maximum accuracy. Simple two-step process ensures reliable measurements every time.
• HAPTIC FEEDBACK (Pro)
Feel it when you hit level. Subtle haptic taps confirm when your surface reaches 0° or 90° — work without looking at the screen.
