Ranked for 2026
The best fly fishing apps of 2026
There are more fly fishing apps than ever, and they’re good at genuinely different things. Some find you water. Some read conditions. One reads the water and tells you the play. Here’s our honest ranking for 2026, from the team that builds Rivus. We use most of these ourselves, and we’ll tell you what each is best for and where each one stops, ours included.
The apps, ranked
1. TroutRoutes, best for maps and access. The best map in fly fishing, and the one most anglers start with. 50,000-plus trout streams, land ownership, 280,000-plus access points, offline maps, and live gauge readings. Where it stops: it hands you the water and the numbers, and won’t read those numbers into a hatch or a fly.
2. Rivus, best for reading the water and calling the play. Every other app hands you something to read. Rivus reads it for you. Today’s flow, water temperature, weather, and hatch for your exact stretch, the play, whether it’s worth fishing, and the best fly from your own box, with Eddy in your pocket when the bite quits. Full disclosure, this is our app. Where it stops: it covers a curated, growing set of trout rivers, not every water in the country, and it won’t find new water or map who owns the bank.
3. FlyFishFinder, best all-in-one map. The most feature-packed of the maps, with big coverage, easement and public-land layers, a fishability badge, and guide-curated picks. The deepest map if you want a light read on conditions too. Where it stops: its conditions read is a badge, not a per-stretch judgment.
4. OnWater, best free access maps. Access-first, with species filters and no paywall on public water. A clean, broad pick across species. Where it stops: it shows you access and raw conditions, not a trout-specific play.
5. FlyGuysNLies, best for western river verdicts. River verdicts, hatch charts, and fly recs read from live conditions across Colorado, Wyoming, Montana, Utah, and New Mexico. The closest app to what Rivus does. Where it stops: a fixed western river set, and no conversational side when the day goes sideways.
6. Fishbrain, best for logging and community. The giant. A huge community, every species, and a deep catch log. Where it stops: it’s broad rather than fly-and-trout deep, so the guidance is thinner than a specialist’s.
7. SnapHatch, best for a quick camera bug match. Point your phone at a bug and its AI names it and matches a fly, even off the grid. A tidy single-purpose tool. Where it stops: it needs a bug in hand, and Rivus does that same photo ID inside Eddy with your conditions baked in.
How to pick
If you need to find new water and check who owns the bank, get a map, TroutRoutes leads there. If you’ve got the map handled and want to know how to fish the water you’re headed to, that’s Rivus. Plenty of anglers run one of each.
