Mareas support
One person reads this inbox, and it's me. Tell me what happened and I'll get back to you.
To save a round trip, include your iPhone model, your iOS version and the app version (you'll find it at the bottom of the app's settings). I usually reply within two or three days.
Common questions
The tide times look wrong for my beach.
Tide models are computed on a grid of points at sea, and the nearest modelled point can be a few kilometres from a bay with its own behaviour. Enclosed bays, rias and Mediterranean spots with tiny ranges are the usual suspects. Send me the place name and I'll look at which point it's resolving to.
It says my place is inland.
If there's no modelled sea within about 330 km the app gives up. If you're on the coast and it still says this, it's a bug — mail me the place name.
The widget isn't updating.
iOS decides when widgets refresh, and it throttles them hard on Low Power Mode. Open the app once and the widget will catch up. If it's stale for more than a day, tell me.
Can I use it without giving my location?
Yes. Skip the permission and search for the places you care about. Everything else works identically.
Reporting a privacy or security problem
If you've found something that exposes user data, mail the same address with “SECURITY” in the subject line and I'll prioritise it. Please give me a reasonable window to fix it before making it public.
