I downloaded trail sense to compare, but they just are apples to oranges. trail sense looks like an awesome app and I'm happy to add it to my collection of useful tools!

This compass app (and level, too) is simply the most polished and perfected version of a phone compass or level that exists. The haptics feedback, to every small animation and detail, to the minimal but feature-packed design.

It is SO thoughtful and laser focused on just being a really really good compass and level.

This should be a native Android app. I bought it on a whim to try it but holy crap it is just so perfect especially if you notice and care about minor details
