Rivus: Fly Fishing

About this app

Rivus reads your river the way an experienced angler would, then tells you the play, whether it is worth fishing today, what is hatching, and what to throw, right now. Open the app on the water and Rivus pulls the live flow and water temperature, the weather that actually moves fish, the hatches that are due, and how fishable it all adds up to today. No more bouncing between a gauge site, a weather app, a hatch chart, and a fly shop blog. One read, in one place. What you get: Live water conditions for more than 180 rivers across 36 states, and growing. Flow, water temperature, and trend, read the way they affect the fishing. A fishability read for right now and the next seven days, so you can pick your day and your water before you drive out. Hatch intelligence tuned to the season, the river type, and today's conditions, with the patterns that match. Eddy, the voice you talk to. Ask what is going on and get a straight, conversational answer. When the bite shuts off or your go-to fly quits working, Eddy helps you read the change and adjust before you waste the morning. Trip planning for the water you are headed to, with a real sense of what to expect when you arrive. Made for canyon water and cell dead zones. Your core reads keep working on a weak signal, so a thin bar at the river never leaves you guessing. Stop guessing at the water and start reading it.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
