Plumb Bob / Leveling Tool

• The app provides you with all the useful functions on one screen.
Endless Ruler
• Whether it's iPhone 14, 11, or iPad Pro - the measurement is always accurate.
• Choose between measurements in centimeters (cm) or inches (inch).
• The entire ruler can be moved to measure lengths wider than your screen.
Compass
• Use the inclinometer display, controlled by your phone's compass this time. You can also save individual values here and use them as reference angles.
Barometer/GPS Altimeter
• With our app, you always have a barometer and altimeter with you.
• The barometer displays the pressure measured by your mobile device in two different units. With the altimeter, you can record altitude differences and view the history in a clear chart. This way, you can record the elevation gained during hikes or bike rides.
• The app now also shows GPS altitude and accuracy.
Audiometer
