### 3/5 — Facile mais fiabilité aleatoire

*2026-08-22*

Utilisé plus de 50 fois cet été, j'apprécie sa simplicité d'usage mais deplore son manque de fiabilité :
- la surveillance se stoppe quelques fois toute seule
- malgré l'achat sur un autre appareil, parfois le "pairing" ne veut pas s'activer.
- en cas de chasse de l'ancre, l'alarme est trop longue a s'activer

### 1/5 — Don’t get it.

*2026-07-31*

Drops out all the time and looses position.

### 1/5 — False Notifications

*2026-07-20*

The app used to function well while pairing. Lately it continues to send critical alerts it hasn’t been notified in 7 mins. I’ve dug everywhere to see why always isn’t available, but the app seems to be using a non standard way to send certificates alerts. 
After killing the app on the receiving device, I continue to get critical notifications while at dinner or sleeping. 
I paid for the lifetime membership, so very disappointed

### 4/5 — Comments from users

*2026-06-26*

Works well, like it so far, but a couple “usability” suggestions:
- the distance from anchor is often hidden behind the boat and/or anchor icons. This number is often all a sailor cares about as it tells him about the motion of the boat. All you need to do is offset it from the icons or display its value somewhere else on the screen. 

- most of us start the alarm after anchoring. We then need to move the anchor location to where it actually is. Your app has buttons to accomplish this. The best way I’ve found (on another app) allows you to drag the anchor icon. Plus, the map is not fixed but instead moves with the phone. So setting the actual anchor location is simply hold the phone in alignment with the boat and drag the anchor icon in the direction your anchor rode is pointed. 

- user guide. A list of features and how to access is needed. Many of my friends have tried the app and not used it because they thought it lacked a feature. But it was a matter of them not knowing where it was. Nothing elaborate needed, just feature list and how to find and use.

### 4/5 — Unverzichtbar geworden

*2026-06-05*

Wir sind drei Monate im Jahr Segeln und ausschließlich vor Anker. Die App ist komfortabel und zuverlässig, leider nicht bei zwei Geräten - hier bricht die Verbindung regelmäßig nach 1-2 Stunden ab, was extrem ärgerlich ist (gerade hier ist Zuverlässigkeit ein MUSS). 

iPad bleibt als Sender mit stabiler Internetverbindung an Bord, iPhone als Empfänger geht an Land. Entfernung nie mehr als 2 bis max. 5km.

Aus diesem Grund nur 4 Sterne

### 5/5 — Saronischer Golf

*2026-05-05*

Super Hilfe, ohne die App habe ich nie ruhig geschlafen und mir alle paar Stunden den Wecker gestellt, jetzt checke ich nur bei einem Alarm die Plausibilität und gehe nicht mehr so oft an Deck. Meine Crew und ich möchten das nicht mehr missen!

### 1/5 — Shuts off after a couple hours

*2026-02-10*

This app worked perfectly for me for over a year until I decided to upgrade to the paid subscription. Once I did that every couple hours it will shut down and loose the anchor and will no longer be set or working and it always does this it wasn’t just a one time thing. Funny as this was the most expensive subscription out of all the anchor alarms

### 1/5 — Not reliable

*2025-12-10*

iOS app keeps restarting not something I can trust.

### 4/5 — Great tool.

*2025-11-21*

Very easy to use and very accurate, however if you want to keep it tight, you need to start it as you drop the anchor. First time I used it, I set the alarm hours after I anchored and it alarmed all night because the ring it sets when started may be centred somewhere where the anchor is already at full stretch. If wind turns, it easily leaves the ring. Only fix is to widen your ring. Set it as you drop the anchor and it is awesome protection!

### 5/5 — A keeper.!

*2025-11-19*

Used this app many times and it works perfectly.! I will definitely continue using this app.! Safety out on a boat is always extremely important and it’s a relief to be able to use apps like this one that you need to count on and you can .!!
