1. 5/5Great app. But…

   This App is fantastic, and will only get better as more information is added to the database. That said, There’s a few things. One, need to be able to add data as a user. Not sure where the actual data is coming from. There’s also a good amount of lakes with datapoints and fish locations. There’s also a LOT of lakes with nothing. My two biggest complaints are this: 1. You need to make an iPad version. That, at this point, there isn’t one with the ease of porting an iOS app to iPadOS in 2025 is kind of shocking. 2. I subscribed on my phone, and I get the “you should subscribe” notifications, but I already do. For such a well designed app, these are the kinds of things we see on rookie apps. Especially the every open notification to subscribe even when I already have. You guys are like 85% of the way there.. The last 15% is what sets you over the top.

2. 4/5Great app, but could use some improvement.

   This app is great for many different applications, and brings a lot of different information that both serious and amateur anglers can appreciate. This app takes in a lot of information and presents it all in one location which is very helpful for a one click option for access to different recourses. This is something that no other app does successfully and they did a great job of making that happen. However there are a few things with this app that I find don’t serve there purpose properly. The first of which is both the “trophy potential” and “fish abundance” labels. I have found that most of the lakes around my area and beyond simply have misleading information about them. Many well known trophy walleye lakes do not list walleye with “trophy potential” but then another lake that is more known for smaller size walleye will receive the “trophy potential” label. This is not only true for walleye, but every other fish species as well. The same goes for the “fish abundance” which just seems very inconsistent with the reality with how many fish are actually in a lake. I understand that they are just estimating, but I think many could take this information too seriously and end up making a fishing trip to a lake only to find the information wasn't consistent with reality. The other issue is the lake contours are poor. If you are looking to get an app to give you lake contours this is not the app for you. I would love to see them upgrade the contours to something more accurate like Lakemaster or Navionics, but I know that’s a big ask. Overall I think this app is very useful and all anglers should take advantage of it, but I would not take the “fish abundance” and “trophy potential” to seriously. The Minnesota DNR website gives you access to all that raw data for free and is easier to digest. I hope that helps some of you.

3. 3/5This app has a lot of potential, but plenty of issues

   At this point, the app is in beta, so hopefully most of the wrinkles will be ironed out. But if they don’t make some major changes, I wouldn’t pay for it. The interface, which is the same as the other onX apps, is great. The mapping is not very good. Contour lines on lake maps are low resolution and not very accurate. The property lines are not as well defined as onX hunt. The area insights are basic, but in my experience, quite accurate. While being able to search for fishing spots is great, the search does not seem to be very good. It misses some lakes that fit your criteria but includes others that don’t. My biggest problem with the app is that the fish survey data is not well presented. It doesn’t match lengths to abundance data, and just presents the best data available. This makes lakes with unstable fish populations look way better than they actually are. Hopefully they improve this app, because it is definitely unique in its approach, but it needs some major work yet before I pay for it.

4. 5/5It’s an all inclusive fish scouting experience

   This app has completely transformed how I plan my fishing adventures. With the ability to filter by species, trophy potential, and abundance, finding the perfect fishing spot has never been easier. One of the standout features is the access to DNR survey data, right at your fingertips, making research seamless and efficient. I also love the built-in weather reports and radar overlays, which are invaluable for keeping an eye on changing conditions while on the water. It’s practical, intuitive, and incredibly detailed. Honestly, this is the only fishing app I rely on now. It’s an all-in-one tool that just keeps getting better with every update. If you’re serious about fishing, this app isn’t just A game-changer it is THE game-changer!

5. 5/5Must have app for the casual, hobby or pro fisherman!

   I was excited to see onX release a fishing based app. I am a frequent user of onX Hunt, so when I saw the release of onX Fish, excited was an understatement. After downloading and exploring the app, it’s definitely easy to use. Especially if you have used onX Hunt. The navigation and depth charts are nearly spot on, the fact that they include land owner information in the app helps to gain access to smaller lakes that only have access through private land. Waypoints with different labels is awesome for marking potential spots that you’d like to fish, where you have landed that trophy fish or where you’ve landed your limit. Don’t sleep on this app. If you like to fish, onX Fish is a must have tool to add to your arsenal!
