### 1/5 — Waste of money

*2025-02-01*

Most of the map are several days old. 
Complete waste of money

### 4/5 — Works well

*2023-03-11*

I like this app.  I am able to select a less affected beach.

**Developer response:** Thank you for your review.

### 1/5 — Doesn’t work

*2023-03-09*

I would like my $8 back. There is no data when I bring up the app. I hard reset my phone, and still nothing.

**Developer response:** This can happen if your phone is completely full and has no space left, or you don't have an internet connection. Please contact Apple directly if you would like a refund.

### 1/5 — Will not update

*2023-03-04*

$8 app the will not display any date.  Waste of money.

**Developer response:** Please try restarting your phone. This is likely due to a connectivity problem that will be resolved when you restart your phone.
