DragQueen Anchor Alarm
Open iTunes to buy and download apps.
DragQueen is a simple anchor alarm. It provides distance and GPS accuracy alarms along with an alarm delay. The alarm is quite annoying and is the perfect thing to waken you at night if it detects anchor dragging to your specifications.
Never use DragQueen as the sole source for any type of navigation.

What's New in Version 1.2
If a lot of background processing occurred on the device, the GPS wouldn't respond fast enough and DragQueen would think that the GPS was no longer available. This version increases the time allowed for GPS response to remove that problem.
A must have for boaters who anchor overnight
I just returned from another month long trip in the Bahamas out of which all but 2 nights were on the hook and used Dragqueen every night. Two words: it works
Indeed the previous version had an issue where it would occasionally shut down in certain conditions but the new one works perfectly.
The key is to set the alarm point for the conditions you are in depending on scope, nearby boats or obstacle. Fir instance when in areas where current reverses with tides and space is limited (in Bahamians cuts or in ICW tidal creeks) I always set it tight to be alerted when the current switches.
iPhone GPS reception is good enough to use it below deck
Suddenly went nuts!
Firstly, I have to say it's a great app, started out fine, and matched my Garmin GPS's distance to anchor within 3 ft.
However... At about 3am, the wind shifted about 90o, and suddenly the alarm went off (nice and LOUD too!) It said the anchor had gone from 60ft to over 120ft distance, which it hadn't, thank god.
Seems just a small bug somewhere in the calculation, when the wind was in the same direction, it was perfect.
I have a mophie on my iphone 6 so i have plenty of battery. It didnt work first time i loaded it, so i removed and reloaded it, works perfectly. I will never anchor at night without it.
