Best way to operate a FlexRadio is using this app sitting in the garden. The implementation is superb and includes many features not in the windows version. Naturally some things are easier in the shack with dual 4k monitors; but within that limit every function is doable. Also app support is great. Detailed and rapid. My experience is with iPad Pro 12.9 6th gen, Flex 6400, TGXL, and PGXL. I have used an iPhone 15 and it works remarkably well but I REALLY recommend the big iPad if you can. W0MPM

SmartSDR is a must for all FlexRadio users. It gives incredible perspectives and usability of the radio. SmartSDR is intelligent, very complete, easy to use and very stable. The latest version is even more so. What a joy! I use both versions, iPhone and Mac, and I can say the same thing about each of them.

Quite impressive with everything that’s been built in to this one app. The fact you can do CW, FT8, and more right in the app is a huge accomplishment. I literally just tried FT8 for the first time from my iPhone while laying in bed. Would love (and would pay) for the ability to do Winlink from the app somehow. If not that, at least a mode like JS8, RTYY, etc where you could do some messaging. Hats off to the developers!

Ich benutze die App schon seit zwei Jahren. Bis jetzt immer fehlerfrei und mit automatischen Updates. Ich bin einfach begeistert.

I purchased this program a couple of years ago for the novelty of being able to remotely operate my Flex radio, the reality is it has been one of my best software purchases to date. If you are chasing DX, parks or fill in the blank, some times your opportunity may not come at a time when you’re sitting in front of your radio. I have worked hundreds of contacts from the hotel room on a business trip or I got a Ham Alert notification that a person, park, or state has been spotted and I am on frequency in short order throwing out my call regardless of where I am physically located.

I was happy to see that the app worked flawlessly after my IPhone 14 upgrade to IOS 18. Great work by the developer to keep the app up to date. He has always been responsive to help needs via the help section in the app. If you have issues, it will direct you to him via email. Great program.

This is what you need to catch that rare DX station, or just keep in touch with ham friends while om the road. Owning a FlexRadio this app gives you that extra value that makes the difference. Not so much space on the iPhone screen for all the functions, but Marcus has done a good job with the design.
