Sleep soundly and don’t worry about your anchor dragging with the easiest-to-use anchor alarm app, featuring:

• Easy to set: mark where you drop the anchor and turn on the alarm once it’s set. The anchor position and drift radius are recorded automatically using your current GPS position.

• Drag alarm: an alarm will sound if you drift outside the radius of the anchorage.

• Low battery alarm: get alerted if your battery drops below 20%.

• Late set: if you forgot to mark where you dropped the anchor, you can simply drag the map to manually set the anchor position or adjust the radius of the anchorage.

• Drift track: View your path as you drift through the anchorage so you can confirm at a glance that the anchor is not dragging.

• Offline support: the alarm does not depend on cell or wifi signal.

What’s New

Version 1.2

After a week of anchoring in beautiful Belize, we're excited to bring you a batch of improvements that resulted from our "field testing":

• Manually adjust the radius of the anchorage by just dragging the circle.
• An issue that could cause the app to crash after several hours of running has been fixed.
• Some small improvements that make it easier to adjust and reset the alarm.
