Smart Distance Pro for Android

Smart Distance Pro for Android measures the distance to a target by a camera perspective. The effective distance is ten meter to one kilometer. To measure the distance, you should know the height (width) of a target. If you know the airplane model, you can measure the distance from the sky. To use Smart Distance Pro for Android, input the height of the target, and touch the screen. If the target is aligned by two lines, get the measured distance.
