"A must-have tool for every angler"
As an avid angler, I've tried numerous fishing apps, but onWater Fish Maps & Forecast stands out as a game-changer. Its intuitive interface and comprehensive features make trip planning and on-the-water navigation seamless. Key Features I Appreciate: Extensive Access Point Database: With over 100,000 fishing access spots, boat ramps, and fly shops, I can effortlessly discover new fishing locations. Detailed Property Boundaries: The clear demarcation of public and private lands ensures I fish responsibly without the worry of trespassing. Offline Maps: The ability to download maps is invaluable, especially when venturing into areas with limited or no cell service. Real-Time Conditions: Access to current weather forecasts and streamflow data helps me decide the best times to fish. The app's design is user-friendly, making navigation and feature access straightforward. Its blend of detailed information, real-time data, and user-centric design makes it a top choice for anyone passionate about fishing.
"onWater is SUPER helpful"
I've been using this app for a while and it's been instrumental in helping me with my daily trips and logging catches. onWater has been super easy to use from day one and one thing I love is when some new feature gets added, they have a short walk through on how to navigate the new feature. Super helpful for someone like myself.
"Wow…. Very well thought out"
You can tell the thought and intention that went into this app! Has all the information you need on the rivers you want… and unlike all the others this is a fishing app for fishermen.. not just species related.. that's a fantastic resource and makes it the go to resource for your trip planning. The fact that it feels like every time I open the app there's new features is enough for me to be a lifetime customer! That intelligent chat.. holy smokes that works like a dream.. it's as if you have all the old fishing buddies wisdom right in your hands!! Get the subscription you won't regret it!
"Great Fishing Resource"
I was initially hesitant about using a fishing app but I'm happy this one exists. The free version is useful: having a curated view of every access point, boat ramp, fly shop, etc directly on my phone means I can plan trips faster. The My Waters dashboard they added recently has also been a game changer — I use it to keep a pulse on all of the live water conditions for my favorite rivers instead of individually checking them on the USGS site, and I have it set up so I get alerts when stream flows are in my ideal ranges. Their team is also really responsive to feedback about the in-app experience. There are a few things like the river measuring tool that are useful but more manual than I expected and it sounds like those are things they're actively working on solving for. I'm stoked to see what this app will look like in a year's time.
"Awesome resource when exploring new water!"
I recently used the offline map tool when floating the South Fork of the Boise River. Because I was unfamiliar with the river and the float, access points, river distances to campsites, whitewater hazards, and other points of interest to the angler, the offline map was invaluable to me in planning and executing the 2 day overnight float. Although near the growing city of Boise, ID, the South Fork runs through a remote and deep river canyon setting without reliable cell phone service, so I downloaded the fully curated off-line map and was able to track my float without a glitch! This helped immensely in understanding where I was in relation to my planned campsite for the night, putting me at ease in the late afternoon by knowing exactly where I would be camping and not needing to push through good evening water to ensure I found my camp while there was still daylight. Also, I was able to see exactly where whitewater hazards were located, enabling me to make better decisions, for example, choosing to set camp rather than trying to run a relatively simple but technical rapid in the fading light of the day. I have always used digital resources when planning a river trip, but the research aspect of this process is tedious, requiring a search of several resources to get the whole big picture. With onWater's app everything is right there in one location making trip planning and the overall experience so simple and incredibly informative with its hand-curated and detailed information. Thanks, onwater!
"Privacy & Conservation Minded"
I believe the app is providing maps and other information in a responsible way by keeping your own marked places and notes private to only you, and providing links to local fly shops and other local services who benefit from people using the app to contact them. I also appreciate their mission to support conservation efforts across the country. Keep up the good work onWater!
"Awesome"
All around this app has been great for exploring new fishing spots. Taken me to a few places I would not have otherwise. All in all I highly recommend this app over TroutRoutes. Both are good but you get more bang for your buck with onWater. My only hopes for this app is that it one day becomes CarPlay compatible and that lake depths are available in CA.
"Skeptical fly fisherman converted"
As someone who generally doesn't love the use of too much technology when it comes to fly fishing, I was skeptical about downloading OnWater. I was pleasantly surprised with both how helpful and how easy-to-use the app is. From private location logs that allow you to record your personal fishing data without exposing any details to others, to the ability to download offline maps so you can always feel confident in remote locations, OnWater is a useful tool to help you fully enjoy every day out on the water.
"Awesome product"
Awesome product. I've always purchased expensive laminated maps in fly shops when floating new rivers. Now all the information is in one, easy to access location that is constantly updated with current river conditions. Especially useful when floating a new river to see exactly how many miles to your take out. No more second guessing where we are when I could be focusing on the fish!
"Great Service From Will"
I emailed the team about a problem with the purchase function of the app. I had built a customized Abel reel through the onWater Blue Line design offering. Once I got to the purchase function it kept dumping me onto the Mayfly main page. Will answered quickly, investigated the issue, and performed an update to the app. He told me how to receive the update and it worked exactly as explained. His communication was A+++ and I was able to order the reel seamlessly.
