My grandma is incapable of using technology, she always ends up stuck in some random menu when just trying to change the channel. I can't always be there to help her with it, so I need something that will make it easier for her to do it on her own.

We have a set-top box and the TV uses IRBlaster to communicate with it, I tried to get her to use voice commands (you can say "Channel 502" and it will change the channel that way but it rarely works for her and usually ends up giving her youtube results which she cant get rid of)

So ideally I'm looking for an app that will let me program 1 of the buttons on the remote to use IRBlaster to go through a list of channels. You hit the button and it goes to the first channel, hit it again and it goes the the 2nd channel on the list, and so on, until the last one where it wraps around to the first channel

I've looked around at a lot of different apps/solutions and none of them are just 1 or 2 button presses on the remote (the set-top box also doesnt have a good solution for it, the favorites button brings up a menu which she struggles to use)

So if anyone could recommend an app that allows changing set-top box channels from a small list of channels with just 1 or 2 button presses it would be very appreciated
