Openstreetmaps with comaps is what I use when I go backpacking, at times having more up to date and accurate information than physical maps. It also does a pretty great job with its time estimations, sometimes it feels the elevation (gain and loss) is off though

alright, links should work for you now. Thanks for checking it out!

yeah I need to add your google play email to the testers list if you’d like to test
