Read full descriptionHide full description
PeakFlows is a river level and forecast app for whitewater kayakers. Over 450 curated rivers across 36 countries, free to use, no paywalled levels. WHAT IT ANSWERS Is it on. That is the question every paddler asks when they look at a river gauge. PeakFlows translates the raw number into a straight answer: low, medium, sweet spot, high, flood. For every river, every hour. No more screenshots of graphs in the WhatsApp group. No more asking the one person in the club who always seems to know. You open the app, you look at the card, you know. LIVE FROM OFFICIAL GAUGES Level data updated every 15 minutes from official national monitoring authorities: OPW in Ireland, the Environment Agency in England, SEPA in Scotland, USGS in the US, BOM in Australia, NVE in Norway, Vigicrues in France, and a dozen more, plus the volunteer RiverSpy network and the PegelAlarm service for rivers they cover. The same data hydrologists use, turned into a paddling verdict. EVERY RIVER EARNS ITS PLACE Over 450 runs, hand-picked. If it's in PeakFlows, it's whitewater worth paddling. No navigation gauges, no flat water, no rivers that never make a wave. 36 countries: Ireland, United Kingdom, France, Norway, Austria, Italy, Switzerland, Spain, and more. COMMUNITY SWEET SPOT Gauge numbers don't tell you if a river is good. Paddlers do. Every river has a sweet spot band voted on by the people who run it. When enough votes come in, the sweet spot shifts to match reality. FORECAST BUILT ON HYDROLOGY PeakFlows forecasts river levels using rainfall, soil saturation, catchment terrain, and how each river actually responds to weather. A forecast specific to your river, not a generic regional rain estimate. Full four-day forecast with Pro. GROUP TRIP Create a trip, invite your crew. The Heads Up button pushes live conditions to everyone on the trip. Free for all paddlers. Not an emergency service: in any life-threatening situation call 112 or 999. WHAT YOU GET FREE Every river. Every level. Every sweet spot. Group Trip coordination. Hazard alerts. Curated photos. Always. WHAT PRO ADDS Full four-day forecast with predicted levels at 3h, 6h, 12h, 24h, 48h, 72h and 96h. Unlimited push alerts. Home Screen widget. Seasonal context. Historical percentiles. EUR 12.99 per year. 30-day free trial, no payment details required.

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.
