SnapHatch and Rivus
SnapHatch’s headline trick is photo ID. Point your phone at a bug and its AI names it and matches a fly. Rivus does that too, right inside Eddy, and it does it smarter, because Eddy already knows the river you’re standing on.
What SnapHatch does well
Scan an insect and SnapHatch names it and recommends an imitation and a presentation, even off the grid, or match it by hand from a catalog when a scan won’t do. It’s got a digital fly box, catch and hatch logging, and animated knot guides. As a single-purpose bug-matcher, it’s a tidy little tool.
Rivus does the photo ID too
Snap a photo of a bug and Eddy tells you what it is and what to throw. Snap a fly you found in a bin and Eddy names it and tells you how to fish it here. That’s the same trick SnapHatch is built around. The difference is that Eddy does it knowing your river’s flow, temperature, season, and what’s actually hatching, so the answer fits the water in front of you, not just the bug in the photo.
What Rivus does
Photo ID is one small corner of what Rivus does. It reads today’s flow, water temperature, weather, and hatch for your stretch, tells you the play and whether the water’s even worth fishing, and hands you the best fly from your own box. And Eddy stays in your pocket for the rest, why the fish quit, what to change, how to fish the run in front of you.
Use both
If you love a dedicated bug-snapping app, SnapHatch is a nice one. But its main trick already lives inside Rivus, next to the live read, the fishability call, and everything else. For most anglers, Rivus has it covered.
