About
IdentaFly is the all-in-one digital companion built by anglers for anglers, designed to eliminate guesswork on the water. At its core is a GPS-powered hatch forecast engine that tells you exactly what insects are hatching at your location right now, so you can plan smarter trips and show up during the right window. The app's Scan-A-Fly feature uses AI image recognition to instantly identify flies in the field — just point your camera and get a match. A deep, searchable database covers thousands of fly patterns indexed by species (mayfly, caddis, stonefly, midge, and more), lifecycle stage (nymph, emerger, dry, streamer), and water type, complete with tying notes and usage tips. Real-time USGS river conditions are integrated directly into each water profile, alongside fish species data, seasonal information, and local regulations. Anglers can build a digital Flybox of go-to patterns, log catches with location and condition data via Catchtivity, and accelerate learning through short instructional videos. IdentaFly covers popular destinations across the United States — from the Green River in Utah to the Au Sable in Michigan — with monthly updated hatch charts. Available free on web and mobile, it is ideal for beginners learning to match the hatch and seasoned fly fishers looking to sharpen their pattern selection.
Key Features

Use Cases
- An angler planning a trip to the Green River in Utah checks the GPS hatch forecast and local water conditions to decide the best week to go and which patterns to pack.
- A beginner at the fly shop uses Scan-A-Fly to photograph an unfamiliar fly in the bin and instantly learns its species, lifecycle stage, and how to fish it.
- An experienced fly fisher logs catches with location and conditions in Catchtivity over a season to identify which patterns consistently produce on their home river.
- A fly tier uses the pattern database to research tying materials and techniques for a specific mayfly hatch they plan to target next spring.
- A traveling angler researches a new out-of-state river using IdentaFly's Waters feature to review fish species, access restrictions, and current flow data before making the drive.
Pros
- Free to Use: The full app is available for free on both web and mobile, making it accessible to all skill levels without a paywall.
- Combines Data & AI in One App: Rare combination of live USGS data, GPS hatch forecasting, and AI photo identification removes the need for multiple separate tools.
- Built Around Learning: Short instructional videos, monthly pattern highlights, and detailed hatch charts make it genuinely educational for beginners and intermediate anglers.
Cons
- Primarily US-Focused: River and hatch coverage is concentrated on US destinations, limiting usefulness for international fly fishers.
- Niche Audience: Designed exclusively for fly fishing, so it has no utility outside of that specific sport.
