Looking for an accessible air fryer

Hi there, I’m looking for an accessible air fryer. I want something that I can use independently, without ann app, without the Amazon echo, simply me being able to use the air fryer. The problem is, I need to be able to set the correct temperature and time, which is difficult even on the manual ones because they aren’t marked in a way that we can read them. Alternatively, if anyone knows how to modify a device that runs on 220 V power to run on 110 V power for the American market, that would work as well because I found a British talking air fryer. Price is no object at this point. My air fryer is on the fritz, and I’m sick of having to use aira to use it every time I want to use it anyway and I wanna just get a robust solution in place.
