Easy to use and not terribly expensive. The only MAJOR issue imo is that the user still can’t correct the offset of the voltages. All battery sensors read incorrectly but they have an offset that is known and could be easy to correct. No one needs to do math. ### 3/5 — Not easy to update motor info *2026-05-19, version 2.14.5* Unable to change the motor info from my old boat. I was as not to change everything else. ### 3/5 — Not very good *2026-04-02, version 2.14.5* This app is not very functional and needs work to keep up. I simply use it to update service records and find it slow and not without loss of data. ### 3/5 — Starlink or WiFi Connection *2025-07-29, version 2.9.2* Siren should improve the capability of the monitoring system by providing a Starlink or Wifi Connection. The Siren System has no cellular connectivity in the Bahamas and many other offshore and International locations. ### 3/5 — Older than 2018 *2024-11-26, version 2.4.2* I would like to use the Siren App Seasonal for my maintenance but not sure how to and what other features I will be able to use. I could use some help on this. ### 1/5 — False alarms *2024-08-18, version 2.1.3* Constantly receive false alarms Siren not returning my emails ### 1/5 — So slooooow *2024-08-12, version 2.1.3* It used to be good. Now I’m getting notifications 5-6 hours after they occur. My boats been secure since noon today after I ran it, and now I’m getting warnings that my engine started, which happened 11 hours ago. ### 1/5 — Difficult to use *2024-08-09, version 2.1.3* Very difficult to use, can’t enter maintenance records ### 4/5 — Now works well *2024-08-08* The system suffered from unreliability when turning the alarm off and on. I contacted support, swapped the sim card with my own all to no avail. I was in a good reception area. An update about 6 months ago fixed that long standing issue and it now works very well. Arms and disarms immediately. ### 1/5 — Service history does not work well *2024-07-29, version 2.0.2* Can’t fix dates of service which is kinda the point ### 3/5 — Need better push alert system *2024-07-22* Would love it if Siren could send their alerts regarding the geofence through a push notification that would also include an alarm sound to your phone as sometimes messages can be delayed or missed unless you are actually watching your phone all the time (I'm not super tech savvy maybe there is a way but I don't know how to set this up? ). What if you are asleep and someone steals your boat. Wouldn't you prefer to get a Geofence broken alarm come through on your phone to wake you up so you can call the police? ### 1/5 — Not useful *2024-07-12, version 2.0.2* I downloaded the app and entered my engine information for two Outboards that I have on my boat only for the app to display cannot be added because it’s under warranty… Tried again after the update still not working. I can add one but not two. ### 1/5 — Brutally awful to use. *2024-07-09, version 1.8.2* Sooooo not user friendly. Almost impossible to use ### 1/5 — Where is the digital outboard owners manual? *2024-06-18, version 1.7.1* My dealer said there was no need to keep the paper manual because I’ll always have access to it on the app. Where are the old owners manuals from the previous app? ### 1/5 — Not intuitive in the least *2024-06-11, version 1.7.1* This is perhaps the least user friendly app I have ever used. Great difficulty in updating service items if completed by owner. Frankly the use and navigation of the site is a joke. ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2026-04-25, version 2.14.5* Why does this even exist. Trash. Can’t load any maintenance. Basically providing no functionality whatsoever. ### 1/5 — Sensors don’t work! *2026-02-01, version 2.12.0* Constantly alerts when nothing is wrong. ### 1/5 — Another Bad Choice *2025-10-26, version 2.11.3* Customer Service is nonexistent, sent multiple requests for assistance with no reply, I get 100 alerts a day for “high water” while the boat is sitting on a trailer without a plug in it and no existing water in the bilge. Will NOT be renewing my service!!! ### 1/5 — Boat Owner *2025-07-20, version 2.9.2* Constantly goes off line . ### 1/5 — The Sat antenna knocks out my GPS *2025-07-10, version 2.9.2* When offshore, the Sat antenna transmits every 5 minutes and knocks out my GPS reception. I’m constantly clearing alarms. The Siren Sat antenna is 20’ from my Garmin and Yamaha gps receivers but it does it anyway. Like the Siren Pro 3 otherwise but this issue is not good and no one seems to have a solution. ### 1/5 — Yahama app disappeared *2025-01-14, version 2.5.2* So tell me again what happened to all my information input in the Yahama app? What if I don’t want to purchase the siren system. Now I don’t have access to service data and records. ### 1/5 — Service Records? *2024-12-25, version 2.4.2* When you try to enter dates for service records, the app changes the dates. It’s impossible to record accurate information. There is no edit button on services. There is no option to choose which type of service (20 hour, 100 hour, etc). ### 1/5 — Unreliable *2024-10-13, version 2.2.3* Do not rely on this app for sat/cell tracking. ### 1/5 — Won't allow service date to be updated *2024-09-17, version 2.2.3* When saving maintenance history the date changes back to input date and not the date I had the engine serviced. Please fix and allow for multiple pages to be attached ### 1/5 — Ineffective *2024-09-12, version 2.1.3* Can’t add old service records, particularly multiple page photo attachments. Pretty much useless. ## Most praised reviews (10 highest-rated) ### 5/5 — Great service *2025-10-04* I had the system from my former owner , I had a difficult to identify the location of one of my sensor location , but call Bruce of Siren , he spent almost whole help me contact the original installer and help me solve this issue clear and friendly, I will definitely continue to be their client and the system working very well let me know all the important information of my new boat . Thanks Bruce Miranda , great job and you have the potential to be a great detective. ### 5/5 — Fantastic *2025-09-23, version 2.10.2* This app is absolutely fantastic!First off,the interface is designed to be incredibly, making it easy to find the features you need at a glance. ### 5/5 — Great way to monitor your boat *2024-10-18, version 2.3.2* The updates a really nice. ### 5/5 — Easy to use *2024-07-24, version 2.0.2* Very good site ### 5/5 — Love this App and Equipment. *2024-07-04, version 1.8.2* It has saved my generator on two occasions. Worth the money and piece of mind. Also a break on insurance. ### 5/5 — Siren Connected Boat *2024-05-23, version 1.7.1* Latest 1.7.1 release shows that the devs are responding to user feedback! Keep it up! ### 5/5 — Peace of mind *2024-05-06, version 1.7.0* Amazing app that truly keeps you connected to your boat at all times! Our family loves the peace of mind that Siren Marine offers. ### 5/5 — Must Have for Boat Owners *2024-04-22* As a new boat owner, Siren Marine gives me peace of mind knowing that my boat is safe and secure. I love the monitoring features that let me know all my systems are at a healthy level and ready for use before heading to my boat. The latest app version has noticeably improved the tile viewing making it easier to get a full view of my boat status in the app quickly. ### 5/5 — So far, so good *2024-04-19, version 1.7.0* So far, I am loving the app! It is helpful and user friendly, so I’m happy! ### 5/5 — Needs 2FA and I see Frequent Toggling of Lower Mode To Off *2024-04-19* This app is lacking 2 Factor Authentication to help secure user accounts. Passwords are not enough. I am seeing some weird behavior of Low Power Mode frequently being toggled off that I intentionally turned On to conserve on battery power. It used to be once a day but is now happening multiple times a day frequently which is frustrating. I at first suspected my account may be compromised but I changed my password and it’s still happening. Low Power mode in the On position should never auto change to Off unless I manually change it myself. I’ve seen similar behavior too when Auto is selected. Auto should stay selected and low power mode should be enabled when the low battery voltage threshold is reached. **Developer response:** Thank you for the idea! Sorry you're experiencing some issues with Low Power Mode; we would love to look into this a little more with you. Please contact our support team at 401-619-4774 or Support@sirenmarine.com and we will troubleshoot this together. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
