Great app otherwise *2026-03-12, version 1.7.14* Needs documentation. I cannot figure out what the wind direction is try to tell me when I click on 2 hours and 24 hours. The colors have no meaning without documentation. And Garmin tech support has no idea either. ### 1/5 — Super Glitchy - OK When it works *2026-03-04, version 1.7.14* The average rating says it all - a solid concept - just works poorly. Do not depend on this app and the system for crucial info. ### 1/5 — Does not work *2026-02-25, version 1.7.14* Doesn’t work. When I open it, there is no option to “create an account” No product support. Clearly a broken app forgotten by Garmin ### 1/5 — Annoying! *2025-12-05, version 1.7.14* After a recent update, the app now requires you to type in your email address and password EVERY TIME you open the app. There no reason for this. Please let use stay logged in when the app is closed. Also, how about enabling Face ID? Garmin is a big company that can do much better than this. ### 5/5 — Works great *2024-12-22* I’ve been using this on my NorSea 27 over the past year, and it has worked great. Thank you! ### 1/5 — Can’t sign in *2024-12-01, version 1.7.9* Neither iPhone nor iPad running IOS 18.1 can sign in. Not since Garmin acquired this system. Email response is “we’ll report it”. Garbage. ### 1/5 — Another Garmin disaster *2024-07-27, version 1.7.9* Total disaster since Garmin took over. Once again, Garmin has screwed up an excellent device. ### 5/5 — Version 1.7.9 fixes problem with location hang up. *2024-04-25* The previous version 1.7.8 failed to run due to being unable to determine my location. This version 1.7.9 has rectified the problem and I was impressed that the previous problem was fixed so quickly. Overall this a useful tool to check on boat location and system parameters when away from the boat. ### 1/5 — Upgrade on 04/22/24 is a Clown Show *2024-04-24, version 1.7.8* The latest update seems to have forgotten my account settings. After entering email address, it hangs up on a screen indicating it needs location data but there is no app setting to enable this. Finally, I deleted and reinstalled the app and it starts up with a camera request to see the QR code on the AIS. For now, I have no way to monitor my boat. ### 2/5 — What Happened? *2024-04-23, version 1.7.8* After multiple emails, finally got it to work. Now with an update it’s all gone again and the app locks up. Whoever is doing your app programming, it’s not good and seems very untested. ## Frequently asked questions about Cortex Monitor ### What does Cortex Monitor do?
