Problem with Switching Rackspaces on my phone

Hi guys, this is my first time posting here. Im a nightclub band keyboardist and I usually use the Roland JUNO DS61, quite a beginner when it comes to GigPerformer and using MIDI live.
I have a few rackspaces, and I can assign my MIDI controller to switch to the next/previous rackspaces easily, that havent been an issue for me. But when I have alot of rackspaces, i barely get the time to search for the right patch, or turn my head to look at my laptop. My MIDI controller doesnt have a display.
So I thought, why not I use my phone to view all my rackspaces and select it from my phone itself, instead of tapping buttons on my MIDI Controller or my laptop (my MIDI controller doesnt have that many buttons for me to assign with anyway)
I own both Android phone (Android Version 10) and iPhone 16 Pro Max.
These are the softwares ive tried in my Android phone: OSC Controller by Adam Katz & TouchOSC. I tried following through some YouTube videos as well, but I cant seem to switch my rackspaces with my Android phone.
All the iPhone apps available seem to be paid apps. I’m unsure about paying to get a software only to switch rackspaces in my Gig Performer, as I’m hoping there would be an alternative.
I’m hoping there would be a software for Android because I’d most likely have my Android phone on stage. I am new to OSC. And I’m okay with using a wired connection as well (and idk, id prefer a wired connection too.

Here are my specs, just incase:
MIDI Keyboard: Nektar Impact LX88+
Audio Interface: Yamaha Steinberg UR22
Laptop: Acer Nitro 5 2018 (i5-8300H, GTX1050 4GB, 16GB RAM)
Phones: HONOR 20 Pro (Android 10)

If anyone of you know a perfect Android app for rackspace switching, do let me know here, and how to set it up with the Gig Performer… I’d really appreciate the help yall!

Thanks in advance

That’s kinda non-trivial.

For a start, if you want to use OSC, then you’d like your OSC app to be able to display the current list of songs (say) and you really need to use something sophisticated that supports that kind of thing. See for example

A simpler approach might be an app that can just send MIDI Program Change messages. You would still need to know the PC numbers for each song. Maybe something like MIDI Commander on Android. (NB – I just looked that up - it seems like it might do the job but I don’t use android and so I have not tried it myself so can’t guarantee that it would work)
