Yachting Magazine: "probably the best dollar you've ever spent"

For more than a decade Anchor Watch has set the standard when it comes to guarding your boat and with over 40,000 users you know your boat is in safe hands.

"Anchor Watch" uses the GPS on your smartphone to monitor your boat's position. If the boat moves outside its limits, the program will alert you immediately. Not only on your device but on any device using your iCloud id.

No more sleepless nights, worrying whether your boat is dragging or not. Sleep sound knowing that a quick glance will assure you that all is ok. When you are onshore for dinner or a drink, you will receive an alert the moment your boat leaves the designated area. You can even track it in real-time.

The third generation of Anchor Watch has been rebuild from the ground up to provide the best user experience. It features sea maps navigation and nautical maps. It conserves bandwidth and still uses sophisticated GPS filtering, which avoids false alerts. You can also run it twice as long on the same battery.

Anchor Watch is meant to keep your boat safe, download now.

1.1.2 has a bug in the radius - wait for the next version

The new developments are very welcome but the bug on the radar radius screen is now a very real problem. You can allegedly increase the swing radius to 200 meters, but it looks to be out by a factor of 10 i.e. it is only about 20m! So not a lot use as you would need to be in shallow water with a short scope for this to have a chance.

I would still like the ability to move the place on screen where you dropped the anchor.

I'm looking forward to version 1.1.3, in fairness to the guys they are pushing the fixes out fairly promptly.

Godsend! Straightforward and reliable.

This is the fourth anchor watch app I have downloaded and it really works! Unlike the others, frankly. The add on features are valuable too - calling out to another phone if the boat moves outside the circle you yourself define. Or changes heading. Strongly recommended.

Used for years

Consistent performance and used many, many times for a reassuring watch at night at anchor. For those who set the ring at 10m remember that GPS wanders. A realistic ring is 100m because you swing the length of the scope anyway.

A great app that works. Thank you.
