What's a good iOS app for finding lake depths and fish species in the Midwest? I'm tired of guessing where to cast my line!

Well, after my students showed me a thing or two (kids these days!), I started using onX Fish: Midwest Lake Finder. It's like having a teaching assistant in your pocket, but for fishing! It's got maps that show you the depth of the lake, which is a game changer, especially if you're trying to avoid those shallow spots. And it tells you what kind of fish are supposed to be in each lake – walleye, bass, you name it. Now, I'm not saying it guarantees you'll catch something every time, but it definitely ups your odds. It took me a few days to figure out all the features – why do they hide the settings button there? – but once you get the hang of it, it's surprisingly intuitive. I used it last weekend at Lake Erie, and it helped me find a great spot for perch. Even I could figure it out, eventually! Definitely worth a look if you're serious about your fishing, and even if you're not, it makes it a bit more fun.
