Locus Map 3 Classic

Needed a solid GPS app for work, and this is solid. Easy to use, and still powerful. The free version has most of what MOST people would need. 7/30 update. it keeps getting better! maps render faster since the update. not that it was bad before, but noticable improvement. just got the watch app on S3 frontier, great for a quick glance and to start tracking.

Updating: not simple to set up but awesome once it works. Definitely kept us going in the right direction on some poorly-maintained wilderness trails. Very deep program - I have a lot to learn to see what else it does. But, once you get past the un-intuitive setup, it's great, rock-solid, feature-rich and easy to use. I spent a good three hours figuring out how to set it up, and would have failed if my friend hadn't helped. It's not THAT hard but you have to download the map you want, then navigate to it on your phone with the app, then enable it in view, which is pretty dense. It would be nice if when you downloaded it, you have the option of "Use This Map?" But, the ability to set pins, use different folders for pins, attach files & photos to the pins, and record your track is pretty solid. It's a deep program, and if you're going to rely on it in the wilderness, sped however long it takes at home to really dial it in and understand it. I still have a lot of learning to do. But, it kept us from taking the wrong trail a dozen times on this past trip, when you're confronted with multiple animal traces, and one is your trail, this app is helpful.

In my 10+ years of using smart phones, this is only the 3rd app I've actually purchased, but by far what I consider the best $$ spent on any app so far. Best on-line/off-line mapping app for Android yet! Great user interaction and flexibility if you're into going off grid. I've just scratched the surface, but very happy with purchasing the Pro version.
