If you’re only going to be listening then I’d say it depends on what type of antenna setup you are planning to have. This type of tuner is mostly useful when you transmit because SWR matters when you’re transmitting, you want a good match.
But depending on the antenna type you could possibly use this thing to tune the antenna for listening. You would need to tune manually though. It’s $300 new, might be better to sell it and get a good listening antenna?
About ten years ago I had my first smartphone, a Samsung. Over the span of a year the pre-installed apps got so bloated that I could only have one or two custom apps installed. There was an SD card slot and I tried to offload the apps to an SD card. Very normal and standard thing to do at the time. Except it didn’t work because Samsung had disabled symlink support in the apps directory. No good reason for them to do that, except to make the phone less useful to its owner. Haven’t bought anything from Samsung since them.
