Ratings and Reviews
Great Anchor Watch App
Just took a trip from Seattle to Glacier Bay AK and back using this app and it worked great. Just launch the app when you are ready to anchor and set the anchor location when you drop the hook. It will track the boat position from that point forward showing on the screen everywhere the boat has been since the set. It allows you to then set a radius alarm for any distance but since it will show the boat position when you back up to set the anchor you will see the radius at that time. Very reassuring to know how your boat is tracking and to do a quick check at night. It does consume a lot of battery so we run it with an iPad left charging. The app works in background as long as you don't close the app so you can use your device for other things and come back to the app and it will show the tracks made since you left it. Need to put your device in a location where it both gets GPS and someone can hear the alarm. Anywhere in the main cabin worked for us. It works with or without internet.
Excellent app---best one by far
My wife and I anchor out probably 60 nights per year. We needed an app that we could rely on as well as one that is easy to use. I have tried several other apps and none are close to as good as this one. When I sense a wind shift I love looking at the color coded lines that clearly show periods of time based on color. The new boat shift will be a new color and you can quickly tell if the boat is lying in the correct area. I also like the remote features so that when we go to shore we have a warning system. I have never written and app review but felt this app was superior and deserved a review.
Outstanding stand-alone, remote monitoring is poor
This app is one of the best stand-alone anchor alarms that I’ve come across. It’s very easy to setup, and it worked as advertised throughout the night. The initial tutorial is helpful. I would give it 4-5 stars for the stand-alone features. One issue is that the alarm functions like any other sound. You can’t put DnD mode or set it to vibrate on your phone. This would be desirable, since I often get text messages at all hours and would like to set DnD but get audible anchor alarms. Most importantly, however, I paid for the app to use its remote monitoring feature. There is no tutorial for it, the FAQ/manual is sparse, and I couldn’t get it to work properly. I was hoping to find an anchor alarm that allows monitoring iOS device-to-device with alarm on the remote phone. I couldn’t get it to work, and I have programming background. At best it’s not user friendly, at worst the feature doesn’t work properly.
Developer Response ,
Please send an in app report for the monitoring feature, we’ll walk you through.
To get the alarm without other disturbances at night, you can use it in ‘plane’ mode. All internet notifications will be disabled without betwork yet anchor can wake you up.
To get the phone vibrate or flash up with the alarm, you can use the basic phone settings
