Free version appears useless – Wikiloc Outdoor Navigation GPS Review
Seems you don't get access to any trails, not even a limited number, with the free version. If you only want to see what trails users have put in than it's fine (tho because users create the trail there are many repeats and not much info, similar to Mapmywalk). Not worth having on the phone tho.
