Bubble Level + Measure Kit

Turn your iPhone and iPad into a complete measuring toolkit. Su Terazisi + started as a precise bubble level – version 2.0 grows it into 12 tools in one clean, ad-free app.

LEVEL & ANGLE
• Bubble level: classic vial on an edge, bullseye level when lying flat
• Two-step calibration for true precision
• Angle finder with plumb line and surface slope
• Read in degrees, percent slope, mm/m, in/ft or 1:x ratio
• Camera level: line up photos, shelves and frames through the camera

MEASURE
• Ruler calibrated to your device's screen, in cm and inches
• Protractor for any angle on screen
• Height finder: measure trees, walls and buildings by aiming the camera

COMPASS & QIBLA
• Clear compass with true or magnetic north
• Qibla direction from your location, with distance to the Kaaba and a gentle vibration when you face it

SENSORS
• Metal detector: magnetic field strength in µT
• Vibration meter: live seismograph with peak and RMS
• Barometer: air pressure, height change and floors
• Sound meter: noise level in dB with average and maximum
• Light meter: illuminance in lux

MADE FOR REAL WORK
• Hold and Zero on every measuring tool
• Save readings, add notes and export them as CSV
• Haptic feedback when you hit level
• Dark and light themes with large, easy-to-read numbers
• Works offline. No ads, no subscriptions, no tracking – your measurements stay on your device.

Sound, light and magnetic readings are estimates from your device's sensors and are not a substitute for certified instruments.
