If you have an android you'll be missing about 50% of the features that are available on iPhone, including simply being able to measure point to point distance. My brother has iPhone and I was struggling to find all the features he had until we realized they were non existent. frustrating to say the least to pay for an elite membership but not get a full featured app.

I switched from OnX Hunt that I used for years without a problem across the country, recording all my tracks. OnX Backcountry has yet to finish recording any of my hikes. I get halfway through a 6-7 mile hike and get an error notice saying track has stopped recording. I click Resume and all of the sudden everything crashes and the tracking stops. It's been two months and over 25 miles of hikes and I don't have a record of one of them because they all failed and dropped.

This app has great features. I had really high hours for it. I used it on several hikes and each one had missing information. Part of the trail was closed or changed, a whole trail was permanently closed. I don't know how they get the trail information. Maybe they need more hikers giving them information. For that price point I need much greater accuracy.
