Anchor Alarm - Anchor Watch

I had two simple Requirements to a Anchor Alarm App: 1. The adjustable swing arc should assume every possible shape, as the maximum distance could be different to each direction. 2. I would like to wake up even if I sleep like a log. Also in case of other problems like poor GPS accuracy or power supply drain. I'm convinced, with this App your anchor watch will be improved in many ways! For sure you know the problem after you set the anchor successfully, you would like to set an Anchor Alarm for your anchor-watch, but later at night the wind shifts from East to West, and exactly in West there is a nasty shoal. Well, with Anchor Alarm you've the ability to set your swing shape in advance as individually as specific for each situation! All feature at a glance: § Individual shapes instead of a fix swing arc § Alarm sound which will wake you § Ship dimensions in true-to-scale representation in the map § Optional alarm on low battery or other power supply issues § Optional alarm on poor GPS accuracy § Optional alarm on low volume / silent mode § Optional alarm if headset is connected § All alarms are active in the background and even if you lock your iPhone. Apple Disclaimer Continued use of GPS running in the background can dramatically decrease battery life. So please do not forget your 12V charger ;-)
