About this app

Turn your Android phone into a practical digital measurement toolbox.
Smart Toolbox gives you essential tools for leveling, measuring angles, checking direction and handling everyday DIY projects directly from your phone.
BUBBLE LEVEL
Check whether surfaces and objects are level using your phone's built-in sensors.
Use horizontal, vertical and surface modes with clear angle readings and an easy-to-read digital bubble.
Calibrate the level for your device, phone case or camera bump, and use HOLD whenever you need to freeze a measurement.
CLINOMETER & ANGLE METER
Measure tilt, slope and inclination with clear digital angle readings.
Use the clinometer for shelves, frames, furniture, pipes, construction projects and other situations where you need to check an angle or slope.
COMPASS
Check magnetic heading, cardinal direction and azimuth.
Smart Toolbox can also warn you when magnetic interference or low sensor accuracy may affect the reading.
RULER & PROTRACTOR
Use your phone as a convenient ruler for small objects in millimeters, centimeters or inches.
Calibrate the ruler to improve physical screen measurements.
The built-in protractor helps you measure angles directly on the screen.
CAMERA LEVEL
Use your camera with horizontal and vertical reference lines to help align frames, shelves, TVs and other objects.
Camera Level displays orientation information directly over the live camera preview.
SAVE AND EXPORT MEASUREMENTS
Capture useful measurements and export results when you need to keep a reference or share your work.
