I've tested several apps over the past few months, including Replica and AirBeamTV.
Recently I also tried apps from Electronic Team. Their free TV Mirror app is good for basic screen mirroring, while DoCast offers more casting features and worked well on my Samsung TV.
I'd still be interested to hear what other people are using and whether there are any better alternatives.
The best app really depends on your TV brand and what you're trying to mirror. I've helped users troubleshoot screen mirroring across Samsung, LG, TCL, Roku, Fire TV, and Android TVs, and there isn't a single app that's best for every situation.
If I were comparing the most reliable options today, I'd suggest:
a). ApowerMirror – Probably the best all-around choice if you want full screen mirroring with decent performance across multiple TV brands. It's easy to set up and works well for presentations, photos, and general screen sharing.
b). AirBeamTV – A solid option if your TV doesn't support AirPlay. It has dedicated apps for many TV manufacturers and generally performs well for everyday use.
c). TV Cast – Better suited for streaming videos, photos, and web content than mirroring your entire screen. If your goal is watching media rather than interacting with apps, it's worth considering.
d). Google Home – If your Smart TV has Chromecast or Google TV built in, this is often the simplest free solution and usually provides a more stable experience than many third-party apps.
One thing I always recommend before installing a mirroring app is checking what your TV already supports. Many modern Smart TVs include Chromecast, Google Cast, Miracast, or DLNA, which can save you from installing unnecessary software.
If I had to choose one overall recommendation for someone without AirPlay, I'd probably start with ApowerMirror because of its broad compatibility and ease of use. That said, if you're using a Samsung TV and have already had good results with DoCast or TV Mirror, it may not be worth switching unless you're looking for features they don't provide.
Out of curiosity, what Smart TV brand is everyone using? In my experience, the "best" app often depends more on the TV's built-in casting technology than the iPhone app itself.
