PeakPal is a backcountry height comparison and
slope angle measurement iPhone camera app.
|Determine if distant points are higher or lower. Zoom in for better accuracy.
|Press green button and save a photo with embossed PeakPal data. Prove you were there.
|Use for avalanche safety. Angle background turns red when in avalanche danger zone (30-45 degrees)
|Compare your elevation relative to other peaks, or incoming clouds. Can be used by pilots to gauge cloud ceilings.
|Determine the angle of trails. Helps with running or hiking decision when previewing mountain running race courses.
|PeakPal works in landscape mode too.
|PeakPal can also be used for the estimation of tree height. And especially, for estimating where a tree will fall ... so the tree doesn't hit stuff you don't want it to hit! Move to a point where PeakPal shows approximately a 45 degree angle to the top of the tree. At that point, tree height will equal the distance from phone to tree plus the distance from phone to ground.
|Finally, PeakPal has a calibration feature. Both pitch, for portrait mode usage, and roll, for landscape mode usage, can be calibrated to a verified-level surface.
