Looking for the best Roku screen mirroring app to mirror my iPhone screen

Hey. I used the Screen mirroring to Roku app to mirror my phone screen to my Roku (I have a Roku Stick 4K without AirPlay), but lately, the app has been glitching a lot with significant delays during mirroring, even in the paid version. Can you recommend an alternative for screen mirroring? Preferably, it should work with an iPad as well. Thanks.
