Hi, my app LanMote just landed in the Mac AppStore.
After install you go to the tray icon and click settings to display a QR code.
Scan it and it makes your phone a remote control for simple actions like:
Volume Up/Down
Play, Pause, Previous, Next
If you want to test for free, I can dm you an Appstore free voucher (still have 100 to give away at the time of posting)
If you’re happy to support a solo-preneur, buy the app for the price of a coffee :)
