The Ocean Signal App allows easy access to Emergency PLB/EPIRB/MOB information as well as live information from your Class B AIS. NFC (Near Field Communication) allows access to PLB, EPIRB and MOB details where operation time, Battery condition and test results can be easily checked and displayed on a mobile device. You can even change settings for your MOB's like adding a MMSI without turning the product on! The use of NFC ensures that maximum battery capacity can be ensured giving you confidence that a Beacon will give maximum performance when required in an emergency situation. WiFi connection to the Ocean Signal ATB1 gives access to live AIS target data along with status and performance details, as well as test and Ownership details for Distress Beacons. Initial configuration with vessel details for the ATB1 Class B AIS is also carried out via the WiFi connection. ## Key features - Emergency beacon information access - Live Class B AIS data - NFC for PLB/EPIRB/MOB details - Battery condition and test results - Change MOB settings - WiFi connection for ATB1 AIS - Vessel detail configuration ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/ocean-signal/id1453183713/reviews.md ### 5/5 — Simple and easy to use *2026-03-19, version 2.5.3* Logged in, scanned my beacon. Everything was pretty easy. ### 5/5 — rescueME MOB1 *2025-02-22, version 2.0.9* As someone who spends a lot of time on the water, I always prioritize safety, which is why I decided to get the rescueME MOB1. I feel so much more confident knowing I have it with me. ### 1/5 — Really poor *2024-12-30, version 2.0.9* Really poor. Crashes constantly and not at all user friendly. Your hardware deserves better than this. You really need to do better. ### 5/5 — Great Application *2024-09-24, version 2.0.4* Top product ### 5/5 — Easy to use. *2024-07-30* Nice looking app, the NFC connects nicely and brings all my beacon data into the app. Great feature. ### 1/5 — Awful piece of AIS equipment *2023-10-04, version 1.7.7* Will not Wi-Fi with my cellular iPad at all. Have spent many hours with sim. Same error messages. I have managed a connection with my iPhone 12 but AIS data is incomplete and no vessel names shown. Just MIMS number. Tried speaking to ocean signal and they sheepishly admitted they know this. Sent first back for warranty claim. Second arrived and same issue Ken ### 1/5 — Impossible to use without phone signal *2023-08-09, version 1.7.7* Initially setup my AIS using this app which was easy and straightforward, however I am now trying to connect my iPad as well and it’s impossible. My iPad does not have a cellular connection (it’s capable but no SIM card is installed) in order to connect to the AIS I need to be on the AIS Wi-Fi network, but in order to authenticate the connection, I need to hotspot to my phone to get internet, and I obviously cannot be on both networks at the same time. If you needed to reconfigure this device whilst at sea, away from an internet connection you would be unable to do so, this is a serious issue and needs to be addressed ASAP. ### 1/5 — Dose not work on iPhone *2023-06-15, version 1.7.7* Will not connect to plb3 on iPhone ### 1/5 — Crashes *2023-01-17, version 1.7.0* Crashes every time I try so scan my PLB3. Nothing happens with my EPIRB3. ### 1/5 — Useless *2023-01-12, version 1.7.0* App crashes every time it scans my PLB3. ## Frequently asked questions about Ocean Signal ### What devices does Ocean Signal support?
