About PeakPal

PeakPal is a backcountry height comparison and slope angle measurement camera app. The iPhone motion processor is used along with the camera to compare the height of a distant object.

PeakPal can be used as a simple "mountain climbing advisor". Determine if you are on the highest point of a mountain. Prove you were on the highest summit by taking a PeakPal, data-embossed photo. Determine if you are on a slope that might avalanche (angle text background turns red if slope between 30 and 45 degrees). Know how steep the slope is that you are climbing (or running, if you are a mountain runner). See if incoming clouds are higher or lower than you.

This app was developed by an Alaskan peakbagger for backcountry travelers. Decades of climbing and decision making in Alaska's mountains led to the development of this iPhone app.

A calibration function for pitch (portrait mode) and roll (landscape mode) has been added. Calibration is accessed through the menu. Instructions are on the Help page. Calibration is simple: 1) Place the back of your iPhone on a verified true-vertical surface, 2) Press the Reset Bias button, 3) Press the Save button, 4) Rotate the phone to landscape orientation and do steps 1 through 3 again. The pitch and roll biases you save will be used as offsets to the iPhone's pitch and roll values. For newer phones this feature may not be needed. But for older phones, like the iPhone 5 and 5s, that used older motion coprocessor chips, it has been reported that pitch could be off by a degree or two. Other changes: Use of quaternions to isolate pitch and yaw for better accuracy, and a few cosmetic changes.
