FlyGuysNLies: Fly Fishing 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 based on current flow, recent trends, water temperature, and historical patterns. Should you fish the South Platte today? Now you know before you leave the house.

SMART ALERTS -- Never Miss Prime Conditions
Ten types of alerts notify you the moment your rivers become fishable: verdict changes, flow thresholds, optimal conditions, temperature, closures, hoot owl restrictions, trends, gage status, hatch timing, and turbidity. Comprehensive alerting at a fraction of what other apps charge.

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

FLY RECOMMENDATIONS -- Match the Hatch Instantly
Stop guessing what to tie on. FlyGuys connects current conditions to the exact fly patterns that are working -- grouped by dries, nymphs, emergers, and streamers. 146 patterns with photos, sizes, and seasons.

RIG RECOMMENDATIONS -- Your Guide in Your Pocket
Get a complete rig setup built for today's conditions. Point fly and dropper pairings, leader length, tippet size, indicator depth, and tactical notes explaining why this rig works today.

FISHING LOG -- Track What Works
Log every trip with fish counts, ratings, photos, and notes. Conditions auto-fill from your river. See your past logs before you fish any river again.

FLY BOX -- Organize Your Arsenal
Build custom fly boxes for different rivers, seasons, or trips. Track what works where and share your setups 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.
