I really like this application. The engine interface is quite easy to use and the import routine works well. Our custom aerials (< gig) and line-work load seamless and look great. The app will crash at times, however I've had a problem with several apps doing the same. I attribute to the hardware. Would love to see better waypoint navigation on the fly as switching from pan to edit gets a bit frustrating. Would also like to be able to use hyperlinks for photos and PDF type files, I think the current os is limiting this app. A windows based tablet would probably grant the ability for multiple apps or widgets to be open in the background. Great app, I've enjoyed it.

For anyone who has GIS data they would like to display on an iphone this is the app. Their data upload is very slick. Initially I had difficulty getting the projection that we use at work to execute, but the support was very responsive and I was able to get it going in short order. For those who use WGS84, you will have no difficulties. Since I bought it there have been several good updates and the developers seem to be actively upgrading the app. Hopefully they will continue to add more options for symbology and labeling. Some of the earlier comments indicate difficulty with exported shapefiles and the like. I too ran into a problem with one shapefile, but I sent it to the developer and they found the problem and updated the app. (FYI: I work on a water distribution system and the program easily handled 14 different point and line shapefile sets, each with 1,000 to 6,000 features (I did use zoom levels to help with performance.))

I've been loving the app and have bragged about its versatility. I use it everyday, all day in my work truck doing field work and in the office. All of my apple devices have it. My primary device is my 4th gen iPad with cellular. The app crashed frequently, especially when changing data settings. That was ok because I knew the update was coming. The phone version made me really excited because of the new map gestures and google maps. However the iPad app has been very frustrating. Constant crashing, lethargic map loading, and the failure of the zoom scale have plagued my device. The phone app has not crashed as often and is faster on the map loading. However the zoom scale is still dead. Hope you guys get this fixed! A little heads up on future fixes would be nice!

Just bought this app a couple days ago. I've imported a few shapefiles from work and they all have worked so far. I have a few suggestions.Work on symbology for multiple categories in each shapefiles. Allowing imports of layers would help with this. A more intuitive table of contents for layer adjustment, toggling and symbolism would be great.Create a toolbar for Id, measure, area, and selection. An option for attribute selection and export of selection as shp would be ideal. A toolbar with some simple analysis tools such as buffer, union, and intersect would make this a more practical program. Also, last but not least an editor feature that allows for polygon and line editing and feature creation as well as attrribute field editing would be awesome.This is a lot to ask for in a handheld GIS app, but I am looking forward to new updates. So far I'm quite impressed with this. You can't beat it for $20!!
