PeakFinder

Better than most with room for improvement. Its hard to read outdoors because it's black and white with whisper thin lines and tiny text (would be nice if text could magnify). The field is view doesn't precisely line up with what the eye sees. You have to try to first find a peak you can match up then go from there. My biggest criticism is that the silhouettes of the peaks are a bit lacking in detail so for example clearly jagged peaks look quite rounded in the app making them harder to ID.

Never finds the peaks you point it at. It tells you that mountains that are south of you are the ones you know to be north of you. Only shows you giant peaks dozens of miles away instead of the names of peaks that are right in front of you. Always needs a huge update every time you open it. I paid for premium some time ago thinking I'd use the heck out of it on my many hiking weekends all around SoCal, yet it disappoints nearly every time I want it to do the cool things it is supposed to do.
