Absolute garbage. Won't import a .gpx file which Viewranger has no issues whatsoever importing. I tried importing the .gpx (which Outdooractive claimed was corrupt) to Viewranger (worked perfectly), sync Viewranger, went on to this piece of junk and did a sync, still not showing up. I'll use Viewranger until it's turned off by the developers, then I'll look to find a suitable app to replace it, which is anything but this.
