The Anchor Alarm comes with options for late set and pause - in case you forget to set the alarm when you drop the anchor you can still do it later.
You can also manually enter the anchor coordinates, in case you saved them on another device.
If you decide to take your device ashore you can pause the alarm and reactivate it later, when you return.

The app can remember the location of your boat when you leave and point you to its location later.
In can also point to your last anchor position in case you forgot to set the boat position.

The application allows you to personalize your experience through customizable settings such as:
• measurement units
• dark/light color schemes and an automatic color scheme based on the sunrise and sunset times
• alarm sounds
• GPS accuracy threshold

Note: The app may use your device's GPS in order to track your position relative to the anchor. Continued use of GPS running in the background can dramatically decrease battery life.

Pretty good

Seems like a good concept. Not really intuitive. It would be much better if you could drag the anchor to where it actually is and have the boat swing from there. The way this is set up, you have to have your phone in your hand and set the anchor position when you drop it. I’m more likely to drop the phone since my hands are full.

Thanks for your review. Please check the "Late set" function, it allows you to point to your anchor and set the distance at a later time.

Update: Great app, especially the late set feature

Nice interface, but app fails to acquire anchor position and immediately shifts to alarm mode. Perhaps needs updating to current iOS?

UPDATE: Issue appears to be related to using “feet” instead of “meters”. Switched to meters and app works great. Upgraded to four stars.

Hi, the app will sound an alarm if the GPS reception is not good enough. Please check the GPS Accuracy in Settings, and compare it to your current accuracy. Just send us an email to and we will assist you. Thanks.
