Ipad Anchor Alarm App?

It must go through batteries?

Usually I leave it plugged into a 12v cig socket, otherwise rechargeable AAs. I started using HH for anchor drag years ago because the helm plotters were too far away from master cabin and in effect I wanted a bedside alarm in the anchor dragged.

Which HH plotter do you use for this?
 
Of interest, I bought Boat Beacon App as it provides AIS function to surrounding traffic. It also incorporates an Anchor/Theft alarm. Fantastic and interesting App. Think it was around £6,
One of the reasons I bought this one was for family and friends to keep informed of where we are at all times for added safety and security. Another reason was to view information of surrounding vessels including their MMSI. So if you need to contact them directly via VHF you can,
Copied the following from information guide.

"Turn on Anchor Alarm in settings (i button). This will raise an alarm on your iPhone if your boat moves more than 50m from your current position or travels at over 0.5Kts for more than 15s The alarm works in the background too. You can also use the Anchor Alarm as a remote Theft alarm. Tap Anchor Alarm in settings and set up an email address to send the alarm to. If the alarm fires you will receive an email with the current position, speed and course plus a google map of the lcoation. You can test the alarm function on land - drop the anchor (turn on the Alarm in settings) and walk away with your phone until the alarm fires. If you don't receive the email please check your Spam filters and folders. "
Doesn't send to phone other than by email. Sure they could change this with future releases.

When viewing channel traffic, it does look pretty hectic out there.

An trusty old Garmin GpsMap76. But any of the old 60, 76 or 72 series HH would do. I have the 12v accessory power lead and we have 12v sockets everywhere inside the boat so easy to use in any cabin at night.

The problem with iPad or iPhone is two fold, battery is eaten when GPS in use so realistically they also need to be plugged into 12v supply or charger, and secondly iOS device GPS fixing indoors (grp + windows) doesn't seem to be as good as marine devices. Also folks tend to use them obscuring gps signal quality when moved about inside the boat triggering false alarms.

Yes I was wondering about the GPS reception with the Ipad. We don't have a 12V supply in our cabin so it would be a prob to keep it charged and of course 240V wouldn't be available. Thats good info. I'll probably go down the route of a handheld GPS. No harm in having a spare GPS on board anyway

Yes, I keep the same HH in the grab bag when doing long offshore passages, and as you said will give a reliable long/lat if the main kit ever packs in. I keep a spare set of AA batteries in the grab bag for the HH VHF and HH GPS. Should be able to pick up a Gps72/76 or GpsMap76/60 on Ebay for a song (ie well under <£100)
 
I quite like drag queen because you can easily centre it on your anchor as opposed to your boat (you just enter that your anchor is bearing XXX to the boat and XXX metres away). The t+c you have to agree to is absurdly onerous but I dont lose any sleep over that

Can't find Drag Queen on IPad app app. Where do I look?
 
I've just downloaded it (Dragqueen) but I just don't understand the definition of "GPS Alarm" It says "The reported GPS accuracy that will cause an alarm"
So, inside my house I'm seeing a GPS Accuracy flicking between 16ft and 33ft. Do I set the GPS Alarm at say 35ft........I'm really not sure what this function is for. Surely the "Distance Alarm" is all you need.
4 inches of snow in Brum and I'm feeling bored!!

√ Back Down the Anchor!
◆ Watch the distances between the Boat and the Anchor(s) to ensure that your Anchor is not dragging while you are backing down

All,
I am sorry for the previous message, if it goes through. I accidentally pasted that text.

We have just submitted an app, Boat Sentry, to the iOS App Store that was designed from the ground up by a cruiser. It is a very powerful anchoring assistance app with some unique and distinct features missing from high-end devices and other apps. As it is free, there is no risk.

Please check out the details at http://www.2BitLogic.com.

Boat Sentry and Boat Sentry R will be debuting for free in the Apple App Store (For iPhone/iPad/iPod) on Monday, July 22nd.
 
Smartphone and tablets don't make ideal devices for Anchor drag alarms because a) they eat their own battery power when gps is on, b) folk move the devices around boat in and out of good gps coverage, c) their gps receivers not as good inside a boat or near a cabin window as inexpensive marine hand held gps. You would nearly want a dedicated spare smart phone plugged into a power source placed beside a window. Also at night I put my phone in Airplane mode to avoid being woken by calls which disables the gps receiver.

Marine handheld are not the right solution if you have a smartphone or a tablet. You should instead consider using an external GPS for your iPhone/iPad such as the the Dual XGPS (the Dual XGPS ) , the bad elf (the bad elf ) or the GNS 2000 (GNS 2000). They'll all offer a better accuracy and they are cheaper.

concerning your 3 points:
a) they eat their own battery power when gps is on,
So will the handheld... plug the tablet to a 12V socket or use an external GPS for it

b) folk move the devices around boat in and out of good gps coverage
It is quite true for a phone, much less for a tablet that will move much less. GPS coverage is not an issue in most modern boats.

c) their gps receivers not as good inside a boat or near a cabin window as inexpensive marine hand held gps. .
I used an iPad and an iPhone with Anchor! (Anchor!) and the result was good. I never had to put them close to a window.

Also at night I put my phone in Airplane mode to avoid being woken by calls which disables the gps receiver.
These external GPS do work while in flight mode.
