## What is Anchor Alarm for Boaters?

Anchor Alarm monitors your anchored boat, and alerts you when it moves out of your defined region. Set and forget: Anchor Alarm works in the background to maintain anchor watch AND let you simultaneously use your iPhone/iPad for other purposes too. Anchor Alarm will alert you if it detects excursions beyond your set boundaries.

Powerful but easy to use: to start an anchor watch session, simply tap the "Drop Anchor" button. This app contains new and very powerful monitoring features, including the following:

• Supports remote monitoring of your boat, so now you can monitor your boat, live, from anywhere in the world*
• Easily configure your protection circle: View your geo-fenced zone on a map and easily adjust your protected region in real-time with immediate visual feedback.
• Operates in the background: Allows you full use your iPhone or iPad while diligently performing its Anchor Watch duties in the background; Play music or games with your device, ok to use other apps: Anchor Alarm unobtrusively maintains anchor watch in the background.
• Works even when you mute or close your device or put its screen to sleep.
• Supports full remote monitoring AND tracking of your boat - play back your boat's track*
• Store and keep track of your GPS position of your favorite anchorages*
• Choose from multiple different alert sound options; When an anchor alarm is triggered this app will be sure to get your attention with its many alert options
• When an alert is triggered, you can snooze the alarm, widen your geo-fence, or simply 'raise anchor'.
• And many more features...

With the Remote Monitoring and Tracking* features, the usefulness of the app is greatly increased:
• Share your live location and tracks automatically with anyone anywhere in the world.
• Your authorized viewers will be able to see you movements live via a secure web browser.
• Remotely monitor and track all authorized (and unauthorized) movements of your boat: track your boat's precise location with high accuracy
• Remotely play back your anchor session tracks with time histories of positions, speeds with direction, and battery status

Anchor Alarm includes a large amount of functionality, some contained within the App, some accessible only when used remotely, from a computer or another mobile device with internet access.

• To start an anchor watch session, tap the "Drop Anchor" button.
• If desired, adjust your alert zone with the provided slider, or enter it directly. Note: default geo-fence radius units are feet, but you can change the units to meters, nautical miles, miles or kilometers via the app's Settings module.
• To end your anchor watch session, tap on the "Raise Anchor" button.
• Activate Remote Monitoring from either the Remote Monitoring module or the Settings module of this app.
• To remotely monitor your current anchor session in live mode, first activate remote monitoring, then start an anchor session. A "Share" button will appear on the main screen of this app. Tap on this button to share the Remote Access URL for the current anchor session.
• To view or share both current and past anchor sessions, select the anchoring session you want to share from the "Remote Monitor" module of this app, then select the "Share Track via Email" or "Share Track via SMS" option.
To view and/or modify other settings of this app, please select the "Settings Module".

Notes: 
- This app can, and does operate in background-mode, for iOS devices with version 4.0 or higher software. If you have version 4.0 or higher operating system on your iPhone or iPad, you can return to the home screen after starting the Tracking Mode on this app, for a silent background operation.
- *Remote monitoring and tracking features require an in-app purchase to activate. 
- Continued use of GPS running in the background can dramatically decrease battery life. We recommend you plug in your device for extended monitor sessions.

### 1/5 — Remote function does not work

*2021-07-22*

Installed on both my iphone and iPad. Paid for and activated remote monitoring. Restored purchases on my phone.  Started an anchor session on iPad, I can see it in the remote monitoring screen but it doesn’t show in the remote monitoring on the phone. 

Even the track sharing function is useless as when received on the phone by email or sms, it doesn’t show and map background. 

Useless and waste of money. I tried using  the support link. None of the links on the developer website work.

### 1/5 — Would not recommend

*2021-04-17*

Alarm does not make a noise goes to snooze 

Not usable

### 1/5 — Don't rely on this

*2020-08-05*

The promise is that it works operating in the background. Just not true. No alarm sounds when the anchor drifts. Just dangerous to rely on this.

### 1/5 — LIES

*2020-01-28*

It says it will work in the background, but it does not! That is FALSE ADVERTISING!

### 1/5 — Waste.

*2019-11-04*

This DOES NOT run in the background.  I tried using it all summer, it resets and asks you to re drop your anchor!!   Terrible.

### 1/5 — No stars

*2019-08-16*

This app is supposed to run in the background. Which it doesn’t. I just set it last night and when I got up this morning it’s wanting me to drop the anchor? What a waste. Give this one a pass

### 1/5 — Useless

*2019-05-05*

Totally useless. Does NOT operate when the phone sleeps. You drift, no alarm.

### 1/5 — App doesn’t work for me Either

*2019-02-17*

Don’t waste your money no support from developer from the app, they want you to up Grade to higher level for $11.99 good luck with that when my $1.49 didn’t  get me any thing and no way to get back

### 1/5 — Not good

*2019-01-20*

Don’t wAist your money

### 1/5 — Sham

*2018-12-28*

I can’t enable GPS positioning in settings or elsewhere so app is totally useless
