AvaAnchor watch
No alarm, a false alarm, or the watch stopped.
The anchor watch is free, for good. It sounds when the boat leaves the circle you set. It runs on the phone, never on our side.
The usual causes
Android stopped it
Settings > Anchor watch lists what Android needs, such as battery optimisation off for Ava and notifications on. Fix any line it marks.
GPS below deck
The watch ignores a position worse than its accuracy limit and says "GPS lost" instead of guessing. Keep the phone near a window or on deck.
On iPhone
Leave Ava open in the background while it watches the anchor. Swiping it away stops the watch.
Tell us what happened
Write to james@smart-hatch.com with the night, the time of the alarm (or when it should have sounded) and the phone model. A support file helps: Settings > Send feedback > Export a support file. We read it and tell you what happened.
Ava is a planning aid. Keep a proper anchor watch of your own on a bad night.
