Video and transcript →BUILT AROUND REAL ANCHORING
Your boat moves.
Your watch should understand why.
A change in wind can move a boat around its anchor. AnchorHoy brings GPS position, an anchor-centred watch area and remote monitoring into one view. Chain length and wind help explain the picture; they do not prove that the anchor is holding.
02
Room for a natural swing.
Enter chain length, depth and wind direction to estimate the anchor position. Your selected alarm radius is measured from the anchor, while swing information adds context to the boat’s movement.

03
Know when the picture changes.
See alerts for movement outside the watch area, unavailable fresh GPS and loss of contact with the boat device. Test notification delivery on your locked shore device before leaving.

Wind shifts.
Context matters.
Move the controls to see the difference between swinging around an anchor and moving beyond the watch area.
Illustration only, not a navigation tool. Real watch settings must also account for depth, boat length, GPS accuracy and local conditions.

FROM DECK TO SHORE
One anchorage.
Two points of view.
1 /
Set your anchor
Enter chain length, depth and wind direction. Check the estimated anchor position and choose a watch radius appropriate to the anchorage.
2 /
Leave a device aboard
Secure a charged GPS-capable phone aboard. Allow precise and background location, and confirm fresh positions before relying on the watch.
3 /
Take the view with you
Pair your shore device and test an alarm with its screen locked. Remote monitoring needs internet on both devices and an active subscription.
BEFORE YOU CAST OFF
Good questions.
Can I download AnchorHoy today?
Android is available on Google Play. iOS is awaiting App Store review.
Will I need two devices?
For remote monitoring, yes: a GPS-capable device stays aboard and another comes ashore. The shore device displays the boat device’s reported position. Local anchor watch can run on the boat device alone.
Does a swing-aware watch prevent every false alarm?
No. Chain length and wind provide useful context, but GPS errors, currents and changing conditions still matter. The aim is better context, not a guarantee that an anchor is holding.
What does AnchorHoy cost?
Anchor watch aboard is free. An annual subscription enables remote monitoring from up to three shore devices. The reference price is €19.99 per year; your store shows the applicable local price and renewal terms before purchase. Manage or cancel the subscription in the store where you purchased it.
