4/5 stars
Great height/distance calculator!

Tested it with trees and buildings and it worked exactly as advertised. I even used it to determine the height of a small mountain in the distance while driving toward it and it was fairly close to the right height when I looked up height of the mountain later.

I would like to see the following features added to this app:

1: Option to include compass heading and angle off horizon in heads up display.

2: Option to take a temporary picture when button is pressed so the reference point of the object being measured is not forgotten and is easier to line up for second measurement.

3: Ability to display distance moved between first and second reading.

4: Ability to calculate approximate location/altitude of distant objects being measured based on current compass heading, GPS location, GPS altitude, and distance to object measured. Estimated location would be displayed on map with level of accuracy as circle on map and numerical value. As well as displaying users current location.

5: Ability to triangulate location/altitude of target object by taking multiple compass bearing readings from multiple locations around the target object as well as height/distance readings from each location to calculate a much more accurate location for the target object. Then display its location/altitude on the map as well as the users location.

6: Ability to determine the distance to a target object based on the difference between the speed of light and the speed of sound.

7: Ability to determine the distance to a wall by using sound based sonar clicks generated by the iphone speaker and then the clicks would bounce off the wall and be heard by the iphone microphone and the time delay would let you calculate the distance.

8: Ability to measure the distance an object has fallen when dropped from a height.

9: Ability to determine distance to target object based on its size in relation to objects with known heights. Use the camera with a heads up display image of said object of know size that can be varied in size which then calculates the distance as well as an estimate of its GPS location/altitude based on the users current GPS location, compass heading and angle off horizon. Then display estimated location on map as well as users location.
