Height Ruler is an app which uses your device's barometer to detect air pressure changes and calculates an object's height.

IMPORTANT! Please check if your device is supported before downloading.

With Height Ruler, you can easily measure anything. For example, to measure your height, just place your phone on the floor, then on your head and back to the floor and this app will do the rest. Then, you will get your height in meters or feet and inches! 

***Please note that you should disable silent mode and turn up the volume to be able to hear audible feedback of whether the measurement is complete.

***Do minimise movements when measuring as doing so would disturb the air pressure and thus yield inaccurate results.

*Developed by Wern Jie, 16.
