Know Where, When and What to Fly Fish 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, and water temperature. Should you fish the South Platte today? Now you know before you leave the house. FISHING FORECAST -- Plan the Week, Not Just Today Most apps show you the weather. We show you the fishing. 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, with the day's expected hatch right beside it. Spot the best day before you take the day off. 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. Your river, your hatch, the moment it matters. 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. 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. FLY BOX -- Organize Your Arsenal Build custom fly boxes for different rivers, seasons, or trips. Track what works where and share 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.
