【實用生產應用app】Two Point Height|最夯免費app-綠色工廠好玩App

Quickly measure the heights of buildings, trees, stomp rocket flights, etc., by first pointing the camera at one end of the object and then the other.

For greater precision you should fill in the height at which you hold the device and your distance from the object.

Other height-measuring apps may require you to enter the distance to the object ahead of time, or to tap first on the base of the object and then the tip, which makes them not work well for all applications (e.g., stomp rocket flight height measurement). Two Point Height lets you select the two points in either order, and to enter the distance afterwards for greater precision.

You can also sight along the side of the phone, which is useful on sunny days as well as for viewing rockets and other small things that are hard to see in the sky.
