Customer Reviews

Balanced Well

I've been seeing this app get unjustly downvoted because certain users are plainly ignorant of what this is for. OTM will not hold your hand. This is not an app for an amateur city person on a weekend stroll, someone who needs 24/7 mobile data. I know it's hard for some people to believe, but your phone is not God, and doesn't work everywhere.

For the skilled adventurer in remote locations, however, this are as good as it gets. There are a wide variety of maps, and more if you upgrade to Gaia GPS. They download easily, but yes, can be HUGE, so use dsl/cable. Once you've downloaded the areas at the resolution you've selected, OTM comes VERY much in handy.

The map maker could improve things by making the interface clearer, and making the maps on device a bit easier to negotiate.

Also, this app used to have Mapquest roadmaps; when Mapquest recently ended their 3rd party service, this was quietly eliminated. Current roadmap options don't cut it. I feel for the devs in this issue. But some heads up for when map servers are cut would be nice, as would a roadmap which has some decent terrain relief and clarity.

Look, kids, for the price, this can't be beat. No subscription nonsense, no clutter, no bloated fees for map packs like other apps... just lots and lots and LOTS of topo maps for jaunts to just about anywhere. That's the deal.

A map maker's go-to app!

There are a lot of map apps out there, have tried several. This is the only one I keep on my phone. The topos are a bit dated, which is to be expected for a free app. When you are hiking, camping, hunting, or otherwise in areas with no cell service, this app will help get you back to civilization....or at least know how far away civilization is. I can think of a lot of map making related reasons to have this app, but the safety aspect of it is a really big reason to have it as well.

Super useful and reliable

I backpack frequently in the Gila, and downloaded this app for that purpose. I have been amazed at how useful it has been across the country and in foreign lands -- it served me well in the Dominican Republic, Spain, and Ireland. I have gotten many times the $10 I paid for it in value.
