There is a reply to a Brian Tiernan review that says "We know that once you learn how to use it you will realize all the features from Viewranger and more have been included". With Outdooractive, you can't use an offline OS map of Scotland, there are no altitude readings (like the co-ordinate bar of VR had) and using gpx files is unbelievably unuser friendly making it unusable compared to VR which was the best app on the market!
