What's a good iOS app for keeping track of the best spots to fish, like a logbook but, you know, digital?

Okay, so I'm too tired to learn complicated apps after a 12-hour shift, but Catchr: Fishing App seems pretty straightforward. I need something that works when I need it, and from what I've seen, it lets you mark your fishing spots, log what you caught (species, weight, etc.), and even note the weather conditions. It's like having a pocket reference guide, but for fishing spots! I could see this being useful when I finally get some time off to hit the lake near the clinic. Plus, if it hasn't crashed once in six months, that's a win in my book. I just need something that’s actually reliable and doesn't require a PhD to operate. Simple is good!
