Great App for the Adventurer

I downloaded the lite version of this app for my latest cross country trip. We hiked up over 14,000ft in Colorado with no service and this app's altimeter, compass, and GPS worked perfectly! I've had a blast keeping track of our altitude from there down to below sea level in San Diego, and throughout the other 8000 miles of our trip. For .99c this upgrade is well worth it for the extras, to remove the ads, and to support the app makers for a great product! Thanks!

Great concept but could use help to get over the top

Great layout and functionality in the pro version of the app. The concept is solid and puts all the resources in the same place a press away from each other. Some of the terminology is tough to understand, refuges for example, (which doesn’t seem to work right) and a couple of the sections still have advertisements when you pay for the advertisement free version ($4.99 US). I really think the developer could take this app over the top if he audited the functionality and reviewed the terminology with someone.

WOW - Comprehensive and Easy To Use

I was in the car and needed the altitude; this App looked good at 99 cents but had few reviews. I'm usually a critical reviewer but I'm very happily surprised.

This small App combines many useful features in a well thought-out interface and they all seem to work fine thus far. This is going on my first page with my most-used favorites.
