AirVPN is okay if you're mainly focused on privacy. It’s got a decent no-logs policy and some nice advanced settings if you’re into tweaking things.
That said, I’ve tried a bunch of VPNs, and honestly, ProtonVPN is just better in almost every way. It has an iOS app, an Apple TV app, works with way more platforms, has faster speeds, and it's open source too. Plus, it actually works for streaming, which AirVPN usually doesn't.
So yeah, AirVPN isn’t terrible, but unless you’re super technical and only care about privacy, there are better options out there.
