Lakemaster one boat network for fishing. Best maps and if you have any humminbird products, you can Bluetooth to them (like control a link trolling motor).
OnX for hunting. Much better than hunt stand in my opinion. A lot of new features and map layers that are very helpful like the range finder feature or the oak tree map layer.
Both have a cost but if you use it frequently, I feel they are well worth it. I spend more money on less useful crap.
