Complicated chart selection, drains battery
High battery usage for background location. Complex and unintuitive UI.
There might be many options but frankly basic ones are not easy to use. Price on sale was better then other apps but if you use NOAA maps in single area, there are apps that win on price too.
So maybe I am just using few features and would appreciate it more if I go deeper. However, I am on the fence of buying competing up instead.
