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…
I’m using a cheapo Antsig smart IR thing instead of my phone. They seem to work with most things I’ve tried to pair them with.
I know it’s not what you’re asking for really, but might be a useful option depending on your use case.
I use them to control the aircon, tv (on / off / aspect reset etc) and stereo volume.
Last time I tried to find a decent universal IR app on the play store, they all seemed to suck. Mind you, that was for my note 3 a few months ago.
Could you provide a link to your product?
Sure.
