I have a hardware device which allows me to stream live free to air tv over my wifi network. The manufacturer has decided to retire to product and has removed the app from the AppStore!?

So, next time I get a new phone I’ll be screwed.

I am not jailbroken, and the last time I was was a while ago.

I have a windows pc, iPhone 8, and iPad Air 2 at my disposal. Both devices have the app in question installed.

Ideally, I would be able to download the IPA and move it to a new device without having to side load it. At this point in my life I don’t really have the time and patience to jailbreak.

Do you guys have any ideas?
