Are you looking for a street navigator GPS app, or something you can use out on your boat? Google maps is OK if you always have data service. It's practically worthless if you don't have data service. If you visit areas where you don't get data, you'll need a paid app capable of storing maps in the device. Since I sometimes drive backcountry roads where I don't have good data signal, I tried a couple of different ones before settling on Garmin Navigon. It gets me where I want to go and rarely crashes on me. Other options are Sygic and TomTom. TomTom was not out when I was looking, but I tried Sygic and it crashed too much on my device. There is no one GPS app that works best on all phones, so try out a few and see which one you prefer.
If you need lake maps, Navionics has an Android app that has the same lakes as their expensive map chips. Shows bottom contours and everything. Costs about $10 and covers all 50 states. They also have a version with HD maps of specific lakes for about $35. I have the US basic map version and I've been very happy with it.

It's nice because the map will show your location on the lake as you move around. It lacks the advanced features of dedicated marine GPS units, but for the price it's a steal. And yes, it will allow you to mark locations and go back to them.
Phone GPS isn't inherently less accurate than a dedicated GPS. They still need to be accurate enough to track a car on a road. It does take them longer to lock onto a signal, and they tend to drop signal easier. That shouldn't be a problem out on the water, though. GPS does tend to suck the battery dry at an astonishing rate, so if your boat doesn't have a 12-volt power socket for a car charger you may want to pack an extra battery.

Don't worry, catch crappie.
