Update: The app keeps improving. The developer responds to feedback. Continues to be a very good app for my needs. Recently I started using a Bluetooth heart rate monitor strap and Trails records its data together with all other data. Read on for my lengthy earlier review which is still very applicable:
I like apps that seem very simple at the surface but have many features deeper down. This new Trails app is one of those. I’ve been using the previous version for about 3 years and transitioned to this new version a few weeks ago. Yes, at first disappointing because the developer has moved to a re-occurring payment model. $2 for 6 months. It’s worth it for me and hopefully the price will not creep up much over time. The usability of the app is outstanding. I mostly use it for running and some hiking. All I need to do is open the app and push Start. That’s it. After pushing Start it counts down 10 seconds (adjustable), enough time to put the phone into my pocket. While the phone is in my pocket the display automatically turns off using the proximity sensor which significantly extends battery life. While running I can simply pull out the phone and see my time, distance and altitude without pushing anything. You won’t appreciate that until you wear gloves, which you don’t have to take off. When you return to your starting point the app automatically stops the timing (can be configured). Under the surface there are many features some of which are a true improvement compared to the older app. More powerful editing of track points, better graphs/stats, addition of waypoints, routing, tie in into the health app (can be configured), etc. (see app description). Another pleasant surprise is a feature where you connect to the app through your computer’s browser while both devices are on the same network. This presents a sophisticated interface with which you can see all your tracks on a world map or specific tracks on a local map, see the stats, graphs, you can filter your tracks and export them to your computer. I like this direct interface since you don’t have to go through any mail or cloud service (even though Trails provides those paths as well). The new Trails app has been running stable (no crashes so far) and has a functional style (big letters where you need them, big buttons where you need them). It also looks pretty stylish, the app, the browser feature and the developers website all have a common theme. Not that I care too much about that but it gives me the impression that the developer put good effort into this and is in it for the long run. He was also responsive to an e-mail request. Since I have been using the older Trails app and now the new one for so long I don’t really have a good comparison to other apps in this category. But the few that I have seen don’t come close for what I need it for.
