.....We use Anchor Watch as an anchor alarm. The part that I love is that it will email my smartphone if the anchor drags while we are ashore. Of course, you need 3G service for it to do so.......
Since I've plugged this app several times, I feel the need to update the reference. It worked great, but has had three upgrades since December and is a disaster now. Buggy, won't let the anchor drop or switch from portrait to landscape. Don't touch it.
The good news is, I have found a better app. BoatMonitor R
. (the app store also has an L and D, but the publishers website takes you to R)
It has all my favorite features from AW. The GPS only knows where there Ipad is, but the anchor is probably 100 feet or more in front of you. This app lets you tell it where the anchor is, so you can set the correct protected swing radius. Then it allows you to set as big or small a protected zone as you like and has an audible alarm to wake you in the middle of the night.
But here are some cool improvements.
First, you can set the protected radius as any slice of the pie, as opposed to the whole circle. This would allow it to sound if wind shifts and you swing outside your initial hemisphere. You could get up to confirm that you remain set, even though you haven't started to drag.
My old app would send an email if the alarm went off, which was great when ashore. I could check my iphone and see if I had an alarm. Both the Ipad and Iphone needed 3G reception, but this was comforting. This new App takes it to a new level !!
It will send a text message, which I find much better than email. I set my phone to ring/vibrate for incoming texts, but had to think to check for emails. The service provides 15 free texts (one per alarm) and sells more for $1.50 per 50 texts. Pretty reasonable, since I've had one alarm in nearly two years and it was a false alarm. GPS signals get screwy from time to time.
Better yet, you can sign onto a website from any computer or phone with internet access and see the same graphic that is on the app on the boat. This was something I always wished the old app would do. If I find the wind is piping up, I always wanted to take a look to see if she was starting to drag, as opposed to wait for an alarm.
Being the dead of winter, I haven't been able to shake this new app down, but it looks promising and broke out the $4.99 for it !!
