**Does Not Work Properly With IOS 7.xx**
** I am working on a fix**
1.6 is finally here all known bugs have been fixed and the anchor offset feature has been added which allows you to set an anchor point after you anchor. Now runs properly on ios version 5.

Anchor Alert was designed to warn you when your anchor drags or breaks loose. It will help protect you from running aground or drifting into other boats while at anchor.

* Just an FYI for those of you that don't know how to close programs that run in the background. Double click your home button(the round button at the bottom of the screen) then you will see all the programs running in the background. Hold your finger on one of the apps until they start wiggling and have an x on them then delete it. That is how you stop apps running in the background it does not delete them like on the main screen. Also this app is not recommended for iPhone 2's.

** Price Reduced from $3.99 to $2.99 one week only get it now before it goes back up!! **

Customer Reviews

Still needs some work to increase ease of use!

I just upgraded to the latest version and I applaud the anchor offset function, however the method of setting up the offset is frustrating to use. I used it this past weekend on the boat and found the procedure for setting the offset by dragging the map almost useless unless the boat was perfectly still.

Many times when I am setting the anchor, I am in a tight cove where I don't have much time to be giving my attention to any thing other than that process. I found that trying to move the map to get the distance correct for the rode length, took too many attempts. It would be much more user friendly if the user could set their anchor, let it dig in, keep the tension on the rode, pick up the iphone, select SET, select OFFSET, enter a DISTANCE, enter a DIRECTION and be done with it.

Allowing the phone to pick a direction by pointing it at the anchor did not work well for me either, as the boat moved from side to side I constantly had to keep looking up and pointing my iPhone at it. It would be much easier to glance at the compass while the rode was tight and enter that heading.

The distance only allows setting the rode length to 125 ft. This value should be increased to at least 200 feet. I commonly anchor with 125 feet of rode and sometimes more depending on the scenario.

Sleep well at sea

This app is fantastic! I bought it while at sea and used it the same instant. The app is so assuring, seeing your boat on the map and knowing that you haven't drifted off out of where your safety ring is placed. Highly highly recommended!!!

Must have app

This is a terrific app for sailors. It saved me from running aground on a stormy night when both of my anchors slipped in a gale. The app woke me up just in time!
