## What is Anchor Alarm with Late Set?

ANCHOR ALARM
The Anchor Alarm app lets you feel safe and secure when on anchor. 
You get instant alerts and notifications when your anchor drags or the GPS reception degrades. 

The app comes with an option for late set: in case you forget to set the alarm when you drop the anchor, you can still do it later. 
You can also adjust the anchor position manually on the map screen.
You can also manually enter the anchor coordinates, in case you saved them on another device.
If you decide to take your device ashore, you can pause the alarm and reactivate it later, when you return.

CUSTOM AREA

The boat movement is recorded and a track is displayed on the map screen.
The app runs in the background and requires no internet connection.

REMOTE MONITORING
Peace of mind, wherever you are. 
With Remote Monitoring, leave one device on your boat and keep track from another in your pocket - so you’ll always know your boat is safe.

In can also point to your last anchor position in case you forgot to set the boat position.

### 5/5 — Best option

*2025-12-17*

Love this app compared to competition.  Features and location are far superior

### 5/5 — Very happy

*2025-09-16, version 6.4*

As a new Boat owner, this app is given me piece at nigh. I can anchor up and not worry about if we are moving. The app is so easy to use.

### 5/5 — Anchor alarme

*2025-07-04*

Superbe application très ludique pas loin de 10 ans que nous l utilisons sans aucun problème 👍

### 5/5 — Great app

*2025-03-16*

I’m loving this app and have really been depending on it when the wind picks up over 20knots. It gives me great confidence visualising the anchor holding.

### 5/5 — Saved Us Many Times

*2025-03-05*

On the boat while cruising, Anchor Alarm is always on when we anchor and keeps us  aware of our situation so we can have a safe nights rest. The alarms don’t leave anything to chance and having this app reduces our anxiety because it’s so accurate.

### 1/5 — Had me all over the place

*2024-09-14, version 5.11*

I used this while at anchor in a breeze and the alarm was going off. But it didn’t look like the boat was moving. 
So, I ran the app while sitting on the porch and yes, it showed me moving in all directions, up to 6meters, within a 5-minute period.

### 5/5 — App is not working backround on iphone

*2024-08-24, version 5.11*

…

### 5/5 — My favorite anchoring app

*2024-05-23*

We are at anchor most of the time and this app has been giving me peace of mind for about the last 4 years or so. It keeps improving and the features generally work well for us. The only bit missing is a sharing feature so I can leave a device on board and share the monitoring with my phone from shore. Then, it’d feel complete. Dark mode is appreciated tho the track and circle could contrast a bit better especially under low brightness. 

I really appreciate the anchorages tab as it gives an overall view if others have been in an area before as well as seeing ahead of a passage some popular or possible spots for anchoring. Really great when you go to unfamiliar places. It’s really one of my top favorite features. 

I use this app in tandem with another where I can remotely monitor from shore. I like the backup but this one is still the first I check and set. 
Thank you.

### 1/5 — Keep shopping

*2024-05-12, version 5.11*

For a paid app expected it to work instead it just goes off and boat has not moved setting your perimeters is arcane and a hassle.

### 5/5 — Fantastic app

*2023-12-09, version 5.11*

This app does everything I’ve been looking for, thanks
