This app is useful when going on treks on high altitudes. There is both a free and a pro version. The free version is perfectly usable. I have not tried out the app much. Indoors, it shows the elevation as 8m above mean sea level, which is accurate. The app uses GPS to find out the elevation the user is at and so is much more accurate than watches which use atmospheric pressure readings to deduce the altitude. The next time I go to the mountains or hop on a plane, I will try out the app and validate its accuracy in a more defined manner. The app also has compass support and can save way points across a trail which can later be used to backtrack your path. Overall, a very good app. If it works as described in field conditions. I am going to purchase the pro version to support the developer.

(Based on 15+ hiking trips this past summer.) Gives fairly accurate reading on first opening the app. But after I switch to use another app and then come back to this app, it sometimes updates, but usually does not. It has been off as much as 900 feet, and stuck at the same reading for several minutes while I'm climbing or descending rapidly. So... very misleading at times. I finally found another Altimeter app that is simpler to understand and updates correctly.

Hello Larry, We are sorry we didn't meet your expectations. We've just published an update to the app with bug fixes and more. for your last issue, if the accuracy of the GPS (+- sign under the altitude) is red so the app will now update the altitude until it's orange/green again. You can contact us at erol1apps@gmail.com to get help.

I liked this app, one of the best for hiking. Unfortunately, it also aids "interested parties" use my data for "legitimate interest". It is possible to disable this by scrolling through I don't know how many buttons and switch them off. Do you honestly think I will go through that charade every time I use the app? Right, I thought so. Therefore uninstalled.

We understand how annoying that must be. We're working on a solution. We hope you'll re-consider the rating once we fix the issue. Update: we added an option to cancel it with a button.
