Montana rivers don't wait. River Rat gives paddlers, fly fishers, and rafters a clean read on 39 rivers across Montana and Idaho – before you load the truck. Know if it's runnable, not just the CFS number. Live readings are automatically classified: too low, bony, ideal, pushy, too high. You see the verdict, not just the number. Plan a trip, not just a day. Save your rivers. Open the Trip Planner, pick a date, and see which runs will be in shape. The weekend digest gives you the one-line read before you open anything. Hatches: type, timing, and fly patterns. Active, approaching, and fading windows by species – salmonflies, PMDs, caddis, and more – with fly patterns and timing notes built around water temperature, not calendar guesses. What's in the detail view: • Real-time water temperature + fish thermal stress alerts (67°F stress, 70°F danger) • Water clarity signal with 24-hour trend • Gage height • Rapids and hazards with class ratings • 7-day weather: air temp highs/lows and precip probability Set alerts. Stop babysitting gauges. Set a threshold – "notify me when the Blackfoot hits ideal" – and let it fire when conditions land. No polling required. Everything saves locally. 39 rivers across Montana and Idaho. Built for the people who actually run them. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

River Runner answers the only question that matters: is it worth paddling today? Every river in the country is drawn in living color — the line's color and thickness change with how much water is actually flowing right now. Whitewater runs glow orange on top. Tap one and you get a plain-English answer: a 0–100 score, Prime / Good / Fair / Poor, and exactly why — today's flow against the run's runnable range, rising or dropping, cold water, wind, and any flood warning. No account, no sign-up. KNOW THE FLOW - A live flow map of the entire national river network, modeled hourly — colored from trickle to huge - 15,000+ USGS gauges with live readings, 7-day trends, and gage height - Tap any river reach for its flow, speed, and what that means in plain words - A "runs near you" list that scores the whitewater within driving range — before you commit to the shuttle KNOW THE RUN - A conditions score for every run, with the reasons spelled out - Runnable range, class, gradient, length, rapid-by-rapid descriptions - Put-ins & take-outs on the map, each with a Drive Here button for shuttle day - Hourly weather for the run itself, not the nearest town STAY AHEAD OF IT - Flow alerts: save a run and get pinged the moment it comes into range - Live NWS flood warnings on the map — always on, always free - A Home Screen widget with the score and flow of the run nearest you - Saved runs keep their last known conditions even with no signal at the put-in MAKE IT YOURS - Record your trips: GPS trail, speed, distance, and that day's conditions - Anonymous riverside reports from paddlers actually standing at the water — location-verified, on the map for 24 hours - A Paddle Guide that explains cfs, classes, and the map in plain English - Easy-read mode: rounded, larger, non-italic type for dyslexic and low-vision paddlers River Runner Pro unlocks unlimited saved runs, alerts, and recorded trips, plus the extra map layers — put-ins & take-outs, wind, rain, air temperature, and drought.
