Cortex Onboard

This app is really great, responsive and fully featured. Super easy setup (basically no setup required). It's a convenient backup to our Cortex handhelds. My only wish is that it supported split screen so we could layer it on top of Navionics Boating.

The idea of the Cortex is fantastic but the execution leaves much to be desired. I’m in tech and have spent more than a day trying to get this to function correctly. It seems to be both an issue with the WiFi hardware (weak signal even standing next to it) and the software. State management seems to be an issue and the WiFi networking will make you tear your hair out. And good luck trying to use the boat network. This needs lots more investment from Garmin to justify the price and make it a recommended buy. For now, skip it.

IMO Vesper is the best marine hardware and software company out there. Everything they do exudes quality, care, and thoughtful consideration. Cortex is no exception, and is a central and critical piece of safety equipment aboard my sailboat. Vesper support is excellent, they’ve been very receptive and responsive to suggestions, and continually rolling out improvements. I do hope all of these positive qualities continue following the Garmin acquisition.
