iFlyGuide is a mobile fly fishing guide that provides hatch chart information, camera and map utilities.

Sort hatches by state, month and river
Take pictures, save GPS coordinates and notes
Plot GPS coordinates and search locations

iFlyGuide currently supports rivers in the western United States. New rivers will be added/updated as hatch chart information is acquired. If your river is not currently supported, the camera and map will still be useful for taking pictures, storing GPS coordinates and notes until your river is made available.

Hatch Chart
Select a state, month and river then choose from a list of potential patterns that could be hatching at that particular time. Get hook sizes, a sample pattern, and a description of the natural. Patterns are sorted into 3 categories: Adult, Emerger, and Nymph. If you wish to purchase the pattern, you can link to an iFlyGuide partner for purchase information.

Camera
Take a picture with the camera utility, save the GPS coordinates and map the location with the Maps utility. Save a name and some notes about it for later. Email the picture to your friends or share it on Facebook.

Maps
Get your current location or the location from any of the pictures you take with the Camera utility.
