If you hike or backpack using USGS quads this is the app for you! US and Canada Topos are included in the base price. You simply download the map(s) you need when on WiFi or Cellular Data and then you can use them where you have no WiFi or Cellular data. Downloading takes seconds. Several easy ways to find the map(s) you want. When you hike you turn on a "track" and it draws your progress on a map. The different Topos can be "stitched" so that progress from quad to another occurs with so margins. Also the track has a graph showing elevation profile. You can see total average speed and speed during a section of the track. Maps are very clear and easy to zoom in and out. App allows you to put Way Points on the map ahead of time to aid in navigation or to ID where you took photos etc. The help button is always present and touching it takes you to the section of help applicable to where you are in the app. The help is organized extremely well and put into tables. Ive used a lot of apps and never seen help this well done. Even includes a complete listing of the dozens of symbols used on topo maps. All this for $8. A bargain.
