Outside Magazine in their Oct. 2009 issue page 26, picked RiverGuide as one of the 5 Best Adventure Apps for the iPhone and iPod Touch.

The Best Adventure iPhone Apps | Outside Online
To celebrate I have requested free coupons for the app from Apple and have 5 more to give out, on a first come, first serve basis.
The RiverMaps update was released today on iTunes and is a free update to all existing owners of the app.
RiverGuide Maps- Allow you to zoom in (double tap one finger) and zoom out (double tap two fingers) on a map to reveal river data. The river gauges are represented by the same icons we used when the river forecasting feature was added. If you tap on a gauge icon a callout will be displayed showing more details about that specific river gauge. As you zoom in on the maps more and more local river gauges are shown.
Detail River maps to all of the rivers are now available from the River Detail View. The Detail River Maps will show three modes, Standard, Satellite and Hybrid(Satellite view with streets labeled) map views, and are also zoomable and scrollable.
Pictures and descriptions of the App can be found on the support website.
