I have been using this app for over 3 years now. Its gotten me out of many binds, such as stranded in Milwaukee needing to find public transportation map, and there it is. Or not positive which trail to take out in the national forest. They have a ton of maps which you can access without cell connection, as long as youve downloaded it first. This is a HUGE benefit when you are deep in the wilderness, away from cell connection. My husband and I travel extensively and have come to rely upon Maplets for getting around on the trails. I highly recommend this app.
