I find the only app in F-droid very lacking, and the couple I tested from the PlayStore lacked many of the technically available controls you can see on IRDB, Global Cache, JP1, etc.
I am seriously surprised there is no open source Android IR remote app that can truly put everything to shame, given that the info is out there. I may contact a friend of mine for a new Android app…
Could you provide a link to your product?
