v5.14.0

App does not have permission to find its own downloaded charts. Also there is impossible to transfer this charts manually, because the route you can give to the app is only inside data folder, which is restricted for the up. And without charts this application kind of useless. Waste of money, and no refund available due to "policy".

v5.14.0

since the last update the tide info page does not let you select the next day or days beyond that. If this can be fixed promptly that would be extremely helpful.

Pretty useless for Navigation around New Zealand. Slow to load even on latest Android. UI is terrible. Save some money and get a different app.

v5.14.0

This is a good app that I have been using since 2020. It is generally stable. Support is tricky, the support forum doesn't appear to have been updated for years. I was unsuccessful registering and getting activation emails. The Android version needs the ability to delete chart files. I downloaded unneeded MBtiles and can't delete them. They are large. Only option appears to be uninstalling. The anchor watch circle is now hard to see. Tide and current, the next / previous buttons are broken.
