Every river tells a story. We help you read it—connecting water, insects, and fly patterns into knowledge you can use before, during, and after each day on the fly.
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.
- 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.

Just bought app and tried it on a few flies. It identified a few and missed a few. They need a way to use Google Lens in there AI. I took a Parachute BWO from my box. They identified it as a Hendrickson. Google lens correctly identified it as a Parachute BWO, even showing the picture from BigY, the company I bought it from. I love the concept. It would be perfect for someone like me who only gets on trout streams a few times a year. Hopefully it will continue to get better.
The Fly-cyclopedia!

I’ve been using this app for several months, and it just keeps getting better!! I’m a commercial fly tyer and avid fly angler. This app has become an extremely valuable resource for me! Not only to track my catches and methods (no more wet notebook paper!), but provides information on the history and additional pattern recipes for flies. The AI identification may not always be 100% accurate, (Identafly says this themselves) but it can get you in the ballpark quickly! Realistically there has to be hundreds of thousands of flies and variations, so to see technology pick up on subtle nuances like this is really quite astounding. I have no doubt this could become the largest collection of flies and patterns ever! Whenever I experience an issue with the app I reach out to Identafly on IG and the problem gets resolved in 24hrs or less. Amazing customer service!Thanks Identafly!
Internet needed
Rob Deeper
You need to have cell service or Wi Fi or the app won’t open. How often do you think I fish where there is cell signal? Let me answer that for you. Rarely. You should at least be able to download the flies so you can use the app while fishing
Great App for Fly Fishing

This app has great features other than the AI fly identifier. I love the fly box, it helps me remember what I need to buy at the fly shop. It also gives you fly options based on the local bugs. I have really enjoyed using it!
