Sorry, I've never checked, I only use the Wikiloc satellite view. Just checked, the map is like Google maps. If I want OS quality I just switch on my Backcountry app. When I first downloaded Backcountry it was my most important app for hiking, nowadays I use it far less and now tend to use a combination of apps. For example, Wikiloc for actual routes, Backcountry for detail and sometimes for direction and Google maps to find specific places. hostels, etc.
I like the idea in principal of devising my own routes, but I've made a promise to my wife and son, that I will try to stay on main trails, going off alone on obscure routes can be potentially dodgy. At my age, falling, stroke or other illness, even in the UK on some of the routes I've hiked, you could be flat on your back for days (and dead to boot) and no one would know that something may have happened to you.
I can offset much of this nowadays by starting my Wikiloc app when I start a route and then click it through to my wife's Skype address, or more people if I want to. She can then glance to see that I'm moving or not in real time. If for example, I did fall with a stroke she would at least know where I am and could direct any medics acordingly.
As I write this it can read a bit complicated, perhaps long winded as well, but it isn't at all, just a simple agreed safety habit and a 30 second routine.
