It is absolutely packed with some great features.
I have been using the app for years now and have had no reason to look elsewhere. They constantly upgrade the app with new features that for me rival and keep it ahead of any other app out there today. You can synchronise up to four mobile devices which is incredibly handy. Also the Viewranger desktop site where you login into the My Viewranger is packed with features and tools that will help you find, share and plan routes.
The OS mapping on it is superb and unlike most GPS units its bright, fast and you have the bonus of smart phone features like panning and zooming etc.
The app itself is free but should you want more detailed Ordnance Survey mapping you purchase it in either individual tiles or in pre packaged areas like National Parks. I bought the 1:250,000 road map for the whole of the UK which I find good enough for all my road riding. I always make sure I have credit available and then when I am heading to an area I don’t have the more detailed 1:25,000 mapping, I download just the tiles I need for that particular hike or cycle. Overtime its surprising how you accumulate detailed mapping for a lot of the UK or certainly the areas you frequently visit.
The online site is packed full of information and when you log into My viewranger you enter a portal of routes and inspiration that include hiking, cycling, running, off road driving etc. This is handy should you want to see whats popular or look for something a little different in an area your about to visit.
I use this area to upload all my GPX files for rides, photography trips, shoots, bikepacking and hikes. Once uploaded and saved, you can make it public so others can see and use it or keep it private. It will also tell you here whether you have the 1:250,000 or other scale tiles for the area your heading to.
Skyline uses the camera on your mobile device to identify and label landscape features up to 20 miles away, transforming your traditional 2D map with augmented reality.
I find this really useful when trying to identify my direction at times. It’s also pretty handy if you just want to test your knowledge of an area.
