Crooked & Greedy

I know, Let’s make an app that works only on iPad and another one exactly like it that only works on iPhone with a different name. That way, we can charge double and the customers are too stupid to figure it out. I think that’s this developer’s mentality!

Crashes constantly

Crashes instantly and constantly on the my new iPad. On my iPad 1 it launches, but it is limited to only 7 days of predictions, even for NOAA stations (I've heard the UK forces a 7 day restriction on their predictions, I guess this is where that comes from. Very silly!).

It requires a network connection to get the predictions, so it's useless on the boat. Would have been nice to know that before buying!

The watch is a gimmick, it is the main view but it doesn't offer very much information and it's in a hard-to-understand format.

The map is almost useless if you zoom out, there are too many pins on the screen and you can't select the one you want without tapping on other pins as well. Zoom out too far, and all the pins disappear and you're left wondering where the stations are. Picking stations using the lists is time-consuming, as you have to drill down through various levels before you get a mishmash list of stations in some arbitrary grouping (why is there a North America (east coast) AND a US/East Coast?)

And finally, all you get are tide stations, there are no currents stations at all. Where I sail, we have a lot of NOAA current stations, but this app has none of them.

Don't bother with this app, there are others that are much, much better.
