Description

Note: This app is discontinued and will no longer receive updates, maintenance and support. It should still work if you do download it - you must follow the instructions.

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.

Features:
• Works with just your device.
• Easy to follow instructions.
• Measures height to a maximum accuracy of ± 8cm (± 3 inches).

Supported devices:
• iPhone 6 or later, except iPhone SE
• iPad Air 2 and iPad Mini 4 or later
• All iPad Pro models

Yup

After some tips from app developer and trying it few times gave good results

Developer Response ,

Hi there,

The measurements provided by the app isn't random - it depends on tiny measurable changes in air pressure as you change elevation (the same way your phone can tell if you climbed up a flight of stairs).

Since this app operates on the basis of surrounding air pressure, it is ideal to make sure you don't move your device for some time, and avoid windy areas (e.g. don't perform measurements near a blowing fan), since simple movements are all it takes to cause the surrounding air pressure to fluctuate, and give inaccurate readings.

Thus, you can always verify that the app works correctly and consistently if you try to measure a static object, like the height of a table, since your device would be completely immobile.

For your convenience, the app would have also provided you with an accuracy metric to tell you how accurate your measurements are.

You can always send an email if you need help. Hope this clarifies!
