If you’re looking for a screen mirroring app for your iPhone that avoids the usual pitfalls like lag and poor quality, consider giving ApowerMirror a try. While yen87 mentioned using the DoCast streaming app (which is pretty solid, tbh), sometimes it’s worth exploring alternatives for a better experience.
For example, ApowerMirror has a feature set that might appeal to you if you want more control over your mirroring. Not just movies and photos, but it does a decent job with gaming too, which is often a tougher test for these apps.
Sure, it might need a bit more setup initially compared to others. But once you get it going, the latency is impressively low, and the quality has consistently been great in my experience. Plus, it allows for annotations and screen recording, which can be useful depending on what you’re doing.
Still, if you want to see if DoCast fits your needs better, you can easily download the DoCast app on the Appstore and compare the two.
Sometimes, it’s just about finding what suits your specific use case the best, so a little trial-and-error might be worth it!
