Very useful. The late set feature is a great asset! ### 5/5 — Anchor Alarm Excelent *2023-08-18* Ten day sail from Pensacola, Fl to Mexico Beach/Port St Joe and back. Experienced many rough storms and anchor drug twice, Anchor Alarm alerted us with a plenty loud signal, not too loud. Easy to use, 35 ft Oday with about a 60 ft anchor line. (10 ft depth below keal) Set Alarm distance at 80 ft, GPS accuracy at 30 ft, draw trace - on (this draws where the boat moves as wind changes or anchor drags), Show Accuracy circle-on, anchor alarm as “doorbell”, Sounds to low volume warning -on…. SLEPT PEACEFULLY, though I am old and as I woke during the night a couple times and visually checked our position for added peace of mind and “all was well.” ### 5/5 — Anchor Alarm Excelent *2023-07-16* Ten day sail from Pensacola, Fl to Mexico Beach/Port St Joe and back. Experienced many rough storms and anchor drug several times, Anchor Alarm alerted us with a plenty loud signal, not too loud. Easy to use, 35 ft Oday with about a 60 ft anchor line.

SLEPT PEACEFULLY, though I am old and as I woke during the night a couple times and visually checked our position for added peace of mind and “all was well.” ### 4/5 — Decent with questionable links *2023-05-25* The app itself is what I have found to be the best regarding our anchoring practices. They have improved upon features however the latest are questionable. They paired with a company “boat vitals” but that company hasn’t put out any updates since July of 2020. They say you need their device which includes a few years of monitoring but nowhere is the price mentioned. That’s a huge red flag right there. Why advertise if your prices are secret? We are actively traveling outside of the US so internet availability is spotty and even when we have a connection, the quality ranges from almost good to very poor. Such a service is useless. What I have also found out is that without internet, you get zero visualizations. No circle, no trace, no map. There is no caching of data. The only way to tell if it is working is using your distance from the anchor coordinates. Too many companies cater to those within more developed areas and zero support for those who travel outside those areas. I mean, that’s the point of using anchor apps, because you are actively traveling and looking for something to keep your stuff safe when not in network, right? I see nowhere anything about sunsets or sunrises or moon phase. App updated this morning. I’ve been without internet for 2 weeks and come back to this hot mess. ### 5/5 — Big thumbs up *2023-05-08, version 5.7* All the features I need. Simple to use and very effective. I live on the hook. An invaluable tool. ### 5/5 — We are in an anchorage w/ 3’ waves *2023-03-12* This app is awesome, it is rough and dark. I would normally stay up all night. I sleep through the night. Just make sure your phone is plugged in. ### 4/5 — My Go To app for anchor alarms *2023-02-09, version 5.6* I’ve been using this app on and off for years but only this year have I been relying on it. It has been a rock steady app and have whittled down the ones I use to this and another that transmits data to a remote base. Updates have been great but they have now removed the coordinate location of the anchor. The Apple Watch component has only start and stop buttons so when I forget to pause it under transit away from your boat, I always hit stop. Unfortunately that stops the entire process so I have to reposition the center every time. Without coordinates showing, I don’t know how far off I am when I’ve set my plotter with the spot. This leads to false alarms almost always at a most disadvantageous time. The anchorage feature is really nice in that it shows locations where others have anchored off. Helpful to look there to see where others have found shelter. 1. Put the anchor coordinates back in the app. 2. Put a PAUSE button in the Apple Watch app. 3. Put a simple graphic (does not need to be interactive) on the watch app showing the green circle with anchor and boat locations. 4. Create a remote version so app can run on a device on the boat and transmit to another device when off the boat. The app is pretty good but could be great. It’s still my main app for anchor alarms. ### 5/5 — Simple and to the point *2022-12-24, version 5.5.1* Simple tool that just works! ### 5/5 — Don’t waist your time *2022-11-14* I have used this app for nearly 3 years, they recently changed the appearance, which I don’t care for but am happy to live with. The real problem is the reliability. I am a full time live aboard and have used this app almost daily for the past 20 months. It began to be finicky a few months ago, but with the recent changes it’s now useless DON’T WAIST YOUR TIME Ryan **Developer response:** Hi Ryan, sorry for the trouble. We hadn't made any changes to the app "few months ago". Also we answered your email and asked if you could provide us with some more details of the issues you are seeing. Thanks ### 5/5 — Wow. Now we can sleep! *2022-10-28, version 5.3* Before I was nervous all night. Now I relax. This app works great!! Super easy!!! ### 5/5 — Awesome App *2022-08-19* I cruise on a Jeanneau 42DS and I just want to say I love this app, it’s fantastic. So simple and so effective. One of the things I like the most is that almost every time I use it I forget to turn it off and while I’m leaving that anchorage the car horn starts beeping, often through my boat stereo, reminding me that it has silently been doings its job in the background protecting my boat. Thanks for an amazing app and thanks for selling it to me for one price and not trying to rent it to me. ### 5/5 — Unsure about your mooring? *2022-08-18* I have used this when picking up a mooring and living on the boat. We have used this app in full gales and it gives piece of mind. Easy to use and it warns you if you slide outside of the designated circle. Maybe a bit nervous but always use this when hanging on a mooring in gale force winds. It works for anchoring also. ### 5/5 — Best *2022-01-30, version 4.7* So far the best I have used ### 5/5 — Works great *2022-01-30* This app has saved me a couple of times when conditions (wind, current etc) turned worse than forecast. Once at 3AM. THANKS ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 1/5 — Inutilisable *2023-08-16* La position gps est complètement erronée. En faisant fonctionner une autre appli d’ancrage en même temps (anchor!) sur la même machine, on constate que ça ne vient pas de la machine à proprement parler mais du logiciel !!! Dommage mais je regrette mon achat car vraiment inutilisable . **Developer response:** Salut delftof, désolé pour le problème que vous observez. Pouvez-vous s'il vous plaît nous envoyer un e-mail à support@weather-navigator.com et nous essaierons d'enquêter sur ce qui se passe ? ### 1/5 — Keeps turning off *2022-07-10, version 4.7* Dangerous ### 1/5 — No remote capability to text *2022-04-18, version 4.7* Any anchor app that doesn’t support texting alarms to another phone is useless!! ### 1/5 — Inutilisable *2021-08-05* Application incomprehensible. Inutilisable. Explication et mode d’emploi absolument incomprehensible **Developer response:** Hi, can you please send us an email to support@weather-navigator.com and we’ll be happy to assist you. ### 1/5 — Non funziona *2020-08-12* Non funziona sempre in allarme **Developer response:** Ciao, puoi inviarci un'e-mail a support@weather-navigator.com e saremo felici di aiutarti. ### 1/5 — Didn’t work *2020-07-09, version 4.7* This app didn’t work at all for me. Every time I set my location (even when I set the margin for over 70ft) the alarm would immediately set off, even though the boat was static. Massive disappointment. ### 1/5 — Worked once.... then not again *2019-04-09, version 3.11* Problems.... ### 2/5 — Liked prior version *2022-12-15, version 5.5.1* Missing late set which allowed better way to locate anchor distance from boat. Current setting sets position at current location. This may be at helm at stern of boat assume 50’ scope 10’ water and boat length 38’ I have spun around anchor 180 degrees and am now 150’ from where set. Anchor location is only about 1/2 or ~78’ can’t just leave alarm distance at 165’ as I continue to swing with wind change. Not useful ## Most praised reviews (10 highest-rated) ### 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. ### 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. ### 5/5 — Fantastic app *2023-12-09, version 5.11* This app does everything I’ve been looking for, thanks ### 5/5 — We are in an anchorage w/ 3’ waves *2023-09-24* This app is awesome, it is rough and dark. I would normally stay up all night. I sleep through the night. Just make sure your phone is plugged in. ### 5/5 — Great app. *2023-08-30, version 5.11* Used this for the first time, while sitting on anchor in 30-35 knot winds overnight. It worked great, alerted me twice, but I had set the meters at a lower amount. Really do recommend this app, my boat friends wish it could be used for Android. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
