### 4/5 — Can’t delete station from favorites

*2024-12-12*

Not sure why some stations(harmonic) you can select datum and some stations(subordinate) you can’t and are locked on Mean Sea level. You can’t delete a station once added as a favorite without unloading the app and the reload. Would be nice to be able to delete stations from favorites.

**Developer response:** Some stations has no datum selections 。you can swipe left to remove stations on select station page

### 1/5 — Can’t select location

*2024-08-23*

Taking on a dot works to give you the name of the station, but it cannot be selected. The Developer has replied that this works. No doubt it is how it should work But it is more broken and a station cannot e selected, regardless of what the developer says!!!

So, the developer says, “check the station is a tide station or current station”. Did that!! Tried several. Stations.  Doesn’t work!! My advice to the developer, after several complaints saying exactly this, sign on to a downloaded copy of your app, to duplicate the actual user experience and see what really happens, instead of using your in-house copy, which may well work correctly. But surely, where there is smoke there is fire - when several people all complain about exactly the same issue, perhaps it deserves a more detailed examination than it is being given.

**Developer response:** Try the new version 2.0.

### 1/5 — Unable to select location for current.

*2024-06-25*

I am able to find locations and save them to favorites for the tide tab, but when I select the current tab the app defaults to Estes Head?

**Developer response:** The tide location is just a tide location. The current location is another location.Independently for each other.

### 1/5 — Can’t select location

*2024-05-22*

I select a location and then it says to tap the dot. I tap the dot again, and it tells me to tap the dot to select
Inoperable in current condition
And I cannot send review because all the nicknames are used

**Developer response:** You can tap a dot in the map then add to favorites or select this station in the view which is below the map. In addition, you can switch the selected station in the favorites list.
