Ratings and reviews

Needs instructions/help. I stumbled thru making it work (kind of). It connects up fine with the usb cable that came with the nanoVNA device. I haven't figured out how to use it without also controlling from the analyzer screen. I also haven't figured out how to get the app to display numbers (swr impedance, etc) like the analyzer display. Where does it put the files it saves? It might be a good app if I could figure out how to get it to give the capability I think it should have.

Update to my earlier review. Found files in Documents, why Files didn't show them initially I don't know. Would still prefer to choose location on sd card. Raw data available in s1p and s2p files is good. Display doesn't show start-end of scan range, eg 7mhz at each step on 40 meter band - maybe has only 1 digit resolution. Other issues resolved by deleting and reinstalling.

have installed this in both my V20 android and the Kindle Fire 10 and it works as advertised you have to purchase the OTG USB cable, in my case USB "C" to USB "A" Female so that you have the correct connection to plug the NanoVNA usb cable into. As with the Computer based software you have to connect and power on the nanoVNA before starting the app. The app will discover the virtual Serial port and ask permission to use it. YES allow it and the program connects and works as expected. Nice thing about this app is that it includes markers that you can enable and set. The markers display nicely on all charts.
