Great app to have

Nat Robins

Altimeter is a really great app to have and use especially for traveling across country and it has really come in handy on a trip when you really don’t know what the elevation is and all that you do is to open it on the iPhone and it will tell you the coordinates, name of city and town and the elevation of the place you are in or near. It is a very handy app and it is very easy and simple to use

Excellent, except....


Best phone App for immediate decimal GPS values and elevations. But town name feature is misleading. At a car wreck on mountainside, App displayed nearest town but in different county ER personnel dispatched from different town. App would be better if it had option to turn town name off.

Major Disgrace

I’m a fan of this app! I travel the mountains of WV a lot on my bike and I enjoy checking the elevations. Makes me feel like I’m more in touch with my surroundings. Accurate enough for my needs and functions well. I recommend it!
