No forms, no bots: you write, and the person who builds the app writes back.

If you're reporting a problem, this helps

• The port you were viewing (and whether it was a preset or a free search).
• The date and time of the value that looks off — remember the app shows the port's local time.
• A screenshot, if you can: worth a thousand words.
• Your iPhone or Watch model and iOS/watchOS version.
• Which source you are comparing against (the harbour's table, another app, lifelong experience…).

Before writing

Many questions are already answered in the FAQ — especially negative heights, times that "don't match" (port local time) and accuracy inside rias. For privacy matters, see the full policy.
