Good GPS app – Boating USA GPS map nautical offline fishing chart Review

I've been using this app since 3 months and it's working well. Well worth the small cost. I was using a dedicated GPS app when i started using this app. And after using it couple of times I think it has all the information I need in a single app. GPS is very accurate and works great for me.
