Angle Level - Measure Angle app for iOS
We at Nallelab build this app to easily measure angles using an iPhone or iPad. For angle measurement the Angle Level app uses temporal sampling of the internal accelerometer sensor.
There are couple settings added for flexibility. With offset setting user can add fixed value to the measured angle. Offset setting can be used to offset some known angle. Unit can be changed between angles and radian. Axis of measurement can be changed to measure either horizontal or vertical axis of the device.
Pro version contains some extra functionality. The Pro can be unlocked using IAP.
In the Pro version latest measurements are saved to a list. The measurement can be also named. The list can be exported to CSV file for further analysis or sharing. Additionally, in Pro version the precision of the measurement can be up to 4 digits and the font of the angle in the main screen can be configured.
