Comments from users

Works well, like it so far, but a couple “usability” suggestions:
- the distance from anchor is often hidden behind the boat and/or anchor icons. This number is often all a sailor cares about as it tells him about the motion of the boat. All you need to do is offset it from the icons or display its value somewhere else on the screen.

- most of us start the alarm after anchoring. We then need to move the anchor location to where it actually is. Your app has buttons to accomplish this. The best way I’ve found (on another app) allows you to drag the anchor icon. Plus, the map is not fixed but instead moves with the phone. So setting the actual anchor location is simply hold the phone in alignment with the boat and drag the anchor icon in the direction your anchor rode is pointed.

- user guide. A list of features and how to access is needed. Many of my friends have tried the app and not used it because they thought it lacked a feature. But it was a matter of them not knowing where it was. Nothing elaborate needed, just feature list and how to find and use.

Unverzichtbar geworden

Wir sind drei Monate im Jahr Segeln und ausschließlich vor Anker. Die App ist komfortabel und zuverlässig, leider nicht bei zwei Geräten - hier bricht die Verbindung regelmäßig nach 1-2 Stunden ab, was extrem ärgerlich ist (gerade hier ist Zuverlässigkeit ein MUSS).

iPad bleibt als Sender mit stabiler Internetverbindung an Bord, iPhone als Empfänger geht an Land. Entfernung nie mehr als 2 bis max. 5km.

Aus diesem Grund nur 4 Sterne

Saronischer Golf

Super Hilfe, ohne die App habe ich nie ruhig geschlafen und mir alle paar Stunden den Wecker gestellt, jetzt checke ich nur bei einem Alarm die Plausibilität und gehe nicht mehr so oft an Deck. Meine Crew und ich möchten das nicht mehr missen!

Shuts off after a couple hours

This app worked perfectly for me for over a year until I decided to upgrade to the paid subscription. Once I did that every couple hours it will shut down and loose the anchor and will no longer be set or working and it always does this it wasn’t just a one time thing. Funny as this was the most expensive subscription out of all the anchor alarms

FAQ

What does the Anchor Alarm / Watch app do?

This app acts as an anchor watch for your boat. It allows you to set a specific radius around your anchored vessel. If the boat moves outside this radius, the app will trigger an alarm on your device to alert you.

What are the key features of the app?

Key features include setting and adjusting the anchor radius with precision, receiving immediate alarm notifications, viewing a history of the boat's location, and a remote monitoring option that connects two devices. It also offers an anchorage search and yacht charter requests.

Is the app free to use?

The app offers a free trial for its anchorage search module for 3 days. While the core anchor alarm functionality is available, certain advanced features or modules may require in-app purchases or a subscription.

What are the compatibility requirements for the remote monitoring feature?

The remote monitoring feature requires a stable internet connection on both devices. One device remains on the boat as the sender, while the other is used by the user on land to receive alerts if the boat drifts outside the designated area.

Can I use this app to find places to anchor?

Yes, the app includes an anchorage search feature. This module allows you to discover anchorages where other crews have previously anchored, helping you find suitable spots for your boat.
