An ambitious effort, but a confusing user interface – Tides Planner Review

There's a ton of data presented in this app, but the numerous cryptic buttons and unlabeled numbers make it a jumble of unusable information. I'm sure the developer can figure out how to use it and what it all means, and maybe you can too, but it's not an app you can just open up and use. It keeps informing me that I "do not have a valid annual license for this port" so I'm not sure what data is being withheld for lack of a license.
