Awesome Handheld GPS Replacement!!

This application went far above my expectations. I am an avid backpacker and have traditionally taken a handheld Garmen device with me as an addition to map/compass. This trip I left the Garmen at home and used this app - on a 60 mile hike through the smokies and Appalacian Trail. Here are my findings:

-Great Battery Life while using the app and keeping the phone in airplane mode. Better than the AAAs I had to lug with my GPS.
-GPS was incredibly fast and accurate (with IPhone 6 at least). The old Garmen took 3 minutes to find the satellites and this licks in within seconds, even down in the forest.
-Map accuracy was good, and used in conjunction with a local trail map was perfect. Pro's know to always take a map and GPS for safety, and this combo was perfect. My old Garmen GPS maps were outdated anyhow and they wanted me to pay to upgrade, and these USGS maps are a perfect balance of functional trails and cost!
-Great controls: using the iPhone control, pinch to zoom, double tap, etc are so much easier than the old joystick style devices and the huge screen is great and far superior to the small LCD you get on those other devices.
-Less Weight; I was carrying my phone for emergencies anyhow, and now I'm using it and have reduced my weight by .3 lbs without the Garmen and extra batteries it needed.

Thanks for making such a great product! I look forward to continued updates and features!

This does work very well

We use it to locate field tile. It does the job. Only wish there were a newer map. The one we get from the county as the county tile runs and are more up to date. Unless there is a change in mother earth, these work. This app is well worth it. And it works with a Dual xgps150, I say this because my iPad is wifi only. We tested it using an apple phone and the topo maps showed my location and the apple phone showed the right location, but wrong place, about 75 yards off. All I can say, it works. If you get the app, read the help section. That I over looked. Just remember, to set the section you want and save it to load into the main map.

Love the App

This app has been exactly what I hoped for. It lets me download maps while I'm at home on my wifi and then I can access them when in the backcountry. The GPS on my iPad even works when I have no service and show my location on my topo map. I have not had a problem with the maps at all. I'm glad I bought them.
