At first glance, awesome, but...

When you go ahead and pay for the fish and coral databases, the app crashes when trying to view the paid for data. One specific is the "false lemon peel tang", as soon as you attempt to scroll to the data the app crashes.

The free part works, just don't waste the money on the pay portions until they fix it.

Great potential, if you actually got what you paid for.

Paid databases won’t load

Paid for the database access and it doesn’t download. Wish I could get my money back as this is a complete waste.

Terrible app

App keeps crashing. Doesn’t show members location. Web version is so much better.
