IdentaFly: Fly Fishing Smarts Fly fishing has a learning curve. IdentaFly is built to shorten it — whether you're just starting out or you've been reading water for decades. - Match the Hatch The Hatch Forecast uses your location to show what's likely hatching nearby. See a bug on the water and not sure what it is? Compare it against quality images right in the app. Works offline too, so no signal isn't a problem. - Public Lands Knowing where to step foot or anchor up is important to keep track of. Browse maps and land designation before your trip, then save offline maps with overlays to get the information you need anytime, anywhere. Just keep in mind that just because it's public, doesn't mean it's accessible, so always double check before you go. - Waters & River Conditions Know before you go. Browse fishing reports, see recommended fly patterns for specific waters, and check live conditions — CFS, temperature, and turbidity — so you're not guessing when you show up at the bank. BONUS: Save your favorite gage stations to your home screen widget for a quick check before you head out. - Catchtivity Log your catches, map them by location, and filter by pattern, date, or water. It's a fishing journal that's actually useful to look back on. - Fly Search & Flybox Search a deep database of flies and aquatic insects. Save the ones you fish most to your Flybox for quick reference on the water. - Instant Fly Recognition Snap a photo of any fly and IdentaFly identifies it in seconds. It's the first tool of its kind built specifically for anglers, and it works when you need it most — standing in the middle of a river wondering what's in the hatch box. - Pro Tips Straightforward advice from experienced anglers — not generic content, just useful stuff. - Community Submissions View photos of fishing waters & bugs on the water. Spot a fly that's not in the database? Submit it. The database grows because anglers contribute to it. Check back for updates to help you get the most out of your flybox! ----- For the official End User License Agreement (EULA), please refer to: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
