## What is Anchor Alarm?

I had two simple requirements for an anchor alarm app:

1. The swing circle should not be just a circle, but should take into account my individual free space, which can be different in each direction.
    
2. I want to be really woken up by an alarm when the anchor is dragging. (I would never wake up from the quiet, one-time alarm tone of my Garmin GPS handheld device)
    

And that's exactly what I already implemented in the first successful version of this app. More and more features were added over time. Now I have completely overhauled everything in Version 2, and I am convinced that your anchor watch will run differently with this anchor alarm app in the future.

You will surely know the problem when you want to set an anchor alarm after anchoring, you don't want the same warning distance in every direction. Because the wind, for example, is coming from the west, but it will turn to the east at night, and maybe there is a shallow water area that you want to be warned about early on. For example, you have enough space to the south or north. I have addressed and solved this problem with this app.

Here's an overview of all the important features:

-   Individual shapes as swing circles instead of just round circles
-   An alarm tone that you won't miss (after the first opening of the app, a less obtrusive tone is configured so that you don't get too startled during your first tests)
-   Your ship's dimensions are shown to scale on the map
-   The track during swinging is drawn on the map, so you can see at a glance when the situation changes
-   You can also optionally mark the anchor on the map
-   False alarms caused by individual bad GPS signals can be filtered out
-   A loud alarm tone also comes on when the device volume is low or off
-   There is an alternative monitoring option with which an alarm is triggered if your ship (or your iPhone) turns a predetermined number of degrees. This way, you can monitor whether one of two anchors (stern and bow anchor) is no longer holding and the ship is turning.
-   All alarms also run in the background and when the iPhone is locked.
-   In addition, you can use one of the two devices to remotely monitor the other. So you can go to the restaurant with the dinghy and still see the view from the device on the boat live. An alarm is also triggered on both devices.

When you're on the water with your boat, you need to make sure the anchor is properly secured and doesn't slip. Therefore, the anchor watch is an important instrument to monitor the position of the anchor and ensure that the boat stays in place. The anchor alarm app is a useful tool that helps you protect yourself from unexpected anchor movements.

My app for anchor watch monitors the position of the ship and sends out a noticeable acoustic signal when your boat changes its position to an unauthorized area. This dragging of the anchor can happen in different ways, for example, due to wind or currents. When the alarm is triggered, you can act quickly and reposition the anchor to ensure that the boat stays in place.

The anchor alarm is an acoustic signal that is triggered when the boat moves outside the preset area. This can help you quickly react to unexpected anchor movements and avoid damage to the yacht. The anchor alarm is particularly useful when you anchor in an unfamiliar environment or when the weather changes.

In summary, the anchor watch and my anchor alarm app are important instruments to ensure the safety of your yacht. With this app, you can ensure that your anchor is properly secured and that the ship doesn't move from its position. If you're on the water and like to anchor, you should definitely use my anchor alarm app to protect yourself from unexpected movements and make your night comfortable and safe.

### 5/5 — Captain

*2026-03-16, version 2.04*

This app is great.

### 1/5 — Poco intuitiva

*2025-10-23, version 2.04*

Poche funzioni, impossibile spostare la posizione dell’ancora manualmente. Utilizzavo altra app per anni che purtroppo non esiste più e questa per me è inutilizzabile

### 5/5 — The Best In Class

*2025-07-10, version 2.04*

I’ve used this excellent app for a few years now. Quite simply it is perfect.

### 5/5 — Solid

*2024-08-27, version 2.02*

Used this a couple of nights recently; once in a nasty Adriatic storm. It’s gives good peace of mind on anchor and buoy. Solid.

### 5/5 — Perfekt 🤩

*2024-08-06, version 2.02*

Vielen Dank für die tolle App. Einfach & effizient. Tut genau was sie soll. Herzlichen Dank und Glückwunsch an das Team.

### 5/5 — Absolut top und simple

*2024-08-02, version 2.02*

Ich hab die App schon länger, finde die Freihandzeichnung extrem wichtig. Manchmal ist das schwojen in eine bestimmte Richtung alarmbedürftig und in eine andere nicht. 

Mit der genial einfachen Verknüpfung der beiden Telefone hat man das über das Mobilfunknetz auf dem anderen Telefon. Man sieht die Schiffsbewegungen und einen Auszug aus Google Maps. 

Für mich absolut top und perfekt gestaltet.

### 4/5 — Tolle App, aber der Stromverbrauch….

*2024-07-11, version 2.02*

Die App funktioniert einwandfrei und ohne Fehlalarme. Auch das Verbinden mit einem zweiten Gerät klappt prima und zuverlässig. Aber der Stromverbrauch ist extrem. Das Handy muss ständig geladen werden. Nachts ist es zwingend am Ladegerät anzuschließen. Dies müsste noch verbessert werden. Dann ist die App mit das Beste auf dem Markt und es gibt fünf Sterne.

### 5/5 — Remote monitoring superb

*2023-07-10, version 2.02*

Finally, an anchor app that does remote monitoring well. All apps can set off and alarm on the main phone but I’ve tried them all with remote monitoring so we can leave a phone on the boat and then go ashore with another one and receive an alarm on that. This app is the best by far - super easy to setup and provides a view as if on the boat or other phone. Loud alarm (unlike some other apps) works really well too. The perfect anchor alarm app. Shame I wasted so much on trying other apps but worth it in the end.

### 1/5 — Leider unzuverlässig geworden.

*2023-04-09, version 2.01*

App ist plötzlich nicht mehr aktiv.
Daher wir sie gelöscht.

### 4/5 — Support eingestellt?

*2022-09-22, version 1.14*

Hallo,

ich bin seit zwei Jahren ein zufriedener Nutzer.
Im Gegensatz zu früher stürzt die App öfters ab. 
Das scheint zu passieren, wenn der Ankeralarm relativ lange aktiv ist. Also länger als ein Tag. Parallel dazu wird das Handy auch wie üblich benutzt. D.h. die App meckert auch öfters, weil eine andere App den Lautsprecher benutzt.
Ich wollte diese Meldung über die Hilfe, Support Funktion der App senden, aber der senden Button ist immer deaktiviert.

## Version history (last 5 releases)

### 2.04 — 2024-09-14

The button for sharing to another device was sometimes cut off and not clearly legible. This has now been fixed.

### 2.03 — 2024-09-05

Improvements for the remote monitoring function with a second device (mirroring). It is now possible to send a link as an alternative to scanning the QR code. This also makes it possible to establish the connection without having access to the device that was left on the ship. In addition, an error message appears when setting up mirroring if there is no internet connection. A few translations and typos have also been corrected.

### 2.02 — 2023-04-16

New:
- Possibility to draw a circle instead of scribble the swing arc
- Different alarm sound to select (from intrusive to inconspicuous)
Fixed:
- Translation fixes

### 2.01 — 2023-03-23

Fixed several text and translation typos.
Improved remote sharing feature.

### 2.0 — 2023-03-05

I completely rebuilt the somewhat outdated version 1 of the app from scratch! There's also a major new feature in this transition to version 2.0, namely the ability to use one device as a remote screen. This means you can leave one device on the boat and take the other with you to the restaurant, always having a live view of the device that's on the boat! Both devices need to have the app installed. This is version 2.0 and I want to extend my heartfelt thanks to Jan who conducted the practical tests in the Caribbean during this time of the year :-)

If you notice anything or have any questions, please let me know!
