About this app

Built for Western anglers. By Western anglers.

FlyGuys is the fly fishing app for Colorado, Wyoming, Montana, Utah, and New Mexico -- not a national app stretched thin across 50 states. We go deep on the rivers you actually fish.

RIVER VERDICTS -- Know If It's Worth the Drive
No other app has this. Our River Verdict system rates every river Good, Fair, or Poor from current flow, recent trends, and water temperature. Should you fish the South Platte today? Now you know before you leave the house.

MAPS THAT SHOW WHERE YOU CAN FISH -- New
Public-land ownership (BLM, USFS, state trust, state access) on every map type, so you know you're not trespassing before you park. Premium adds property boundaries along the river corridor, premier and Gold Medal waters, boat ramps and access points, and campgrounds. Tap any parcel or point for details. Topo, satellite, hybrid, and fullscreen maps, plus offline downloads for the Intermountain West.

FISHING FORECAST -- Plan the Week, Not Just Today
Every day in the forecast gets its own fishing rating -- Excellent, Good, Fair, or Poor -- built from flow, water temperature, conditions, and what's hatching. Not just weather. Fishing days.

HATCH ALERTS -- Be There When It Starts
Get a push the moment your river's hatch is on, so you're there tying on the right fly at the right time.

SMART ALERTS -- Never Miss Prime Conditions
Ten alert types: verdict changes, flow thresholds, optimal conditions, temperature, closures, hoot owl restrictions, trends, gage status, hatch timing, and turbidity.

HATCH CHARTS -- What's Hatching Right Now
River-specific hatch timing, not generic regional data. 12-month emergence calendars for every river, with 59 aquatic insect profiles including ID photos and life stages. Free -- competitors charge for it.

FLY RECOMMENDATIONS -- Match the Hatch Instantly
FlyGuys connects current conditions to the exact patterns that are working -- dries, nymphs, emergers, and streamers. 146 patterns with photos, sizes, and seasons.

RIG RECOMMENDATIONS -- Your Guide in Your Pocket
A complete rig built for today's conditions: point fly and dropper, leader length, tippet size, indicator depth, and notes on why it works today.

FISHING LOG AND FLY BOX -- Track What Works
Log every trip with fish counts, ratings, photos, and notes; conditions auto-fill from your river. Build fly boxes by river, season, or trip and share them with friends.

REFERENCE LIBRARY -- Everything Offline
146 fly patterns with tying recipes, 59 aquatic insects, 33 fish species, 10 essential knots -- all bundled in the app. Works without cell service.

RIVERS WE COVER IN DEPTH
180 rivers across Colorado, Wyoming, Montana, Utah, and New Mexico -- from the South Platte, Arkansas, and Frying Pan to the North Platte, Green, Madison, Missouri, Provo, and San Juan.
