CAST™ provides users with the ability to easily view, analyze and share sensor data to evaluate and improve performance. Simply install the CAST™ app on your iOS device to view available NMEA data over a BLE or network connection. Create custom gauges and page views to see only the data that is important to you. CAST™ allows the user to perform speed, temperature, and attitude calibrations without the need for additional converters or cables. And, in addition to firmware updates, the app also logs all of the NMEA sensor data over a customized time period for analysis. Smart devices with Bluetooth connectivity can be used to view the data, creating a mobile powerhouse for your application.

Unfinished Work Here

I can connect to my Yacht Devices WiFi and obtain an NMEA stream that is displayed in Sensor Data. But it cannot connect to my Navico WiFi-1 hotspot, or devices on my network that send NMEA-0183 from over the WiFi-1 hotspot, like my iKommunicate SignalK gateway.

The Ownship Data tab has data updates even without any valid connections - the Heading (True) is just counting up from 0 to 360, continuously.

The Devices Discovery mode finds nothing for me. I have a P79 depth sensor and a B164 broadband sounder connected to Simrad’s BSM-1 interface. I also have a 220WX weather station that isn’t found.

The logging is to a .SDS file. I’m not sure what reads this format.

Custom display pages can be added, but cannot be deleted.

Not useful at least on a phone

Installed this on a 7 w/10.3.3 and without sensors to try it out. It's pretty clunky & doesn't display well either in portrait or landscape modes, regardless of what font size is.

Supports speed, depth & gps.

Customize doesn't have a delete option so once you add something you can't delete it.

It doesn't appear to have screens for wx products.

It has a update history that suggests its actively being developed but as it is it seems useless.
