When entering a boat length, can't move the number keys to find an "enter" method. Makes entire app useless.

Sorry for the misunderstanding. It is the "done" button top right.

Latest version devours your battery

I noticed lately that something was burning up my iPhone battery. Turns out it was the latest version of this app. Even when I turned off background updates, it was by far the number one consumer of my battery life.

So, regretfully, I deleted it.

Major limitations. Expect to be spammed.

You have to register an email to use this app, and they will spam you with no way to stop it.

Even ignoring that, the app is missing a bunch of basic features like the ability to delete a boat.
