Has anyone tried the new Spirit Box apps? Any good?

I've been seeing a lot of chatter about mobile apps that purport to be spirit boxes - white noise generators with supposed spirit communication capabilities. There's one called 'Ethereal Voices' that's got decent reviews on the App Store, and another called 'Spectral' that claims to use AI to filter EVP patterns.

Before I fork out £4.99 on either of them, I wanted to ask if anyone here's actually used them and got any results. I'm skeptical but open-minded - I know they're based on the same principle as the old Frank's Box concept, but obviously a phone app can't do anything an actual piece of equipment can do.

Are they just novelties or has anyone recorded anything of interest with them? And more broadly, what's everyone's view on app-based paranormal investigation tools?

I tried Ethereal Voices for a tenner (couple of quid more than the App Store price for some reason - never got a refund) and it's basically just white noise with random frequency sweeps. I asked it questions and got absolute nonsense. Not even clever nonsense, just random tones and static. Mate, you might as well use a radio tuned between stations.

The problem with app-based spirit boxes is that they're basically just random noise generators. There's no actual mechanism by which an app could facilitate spirit communication that would be different from a hardware device. If genuine spirit communication through white noise is real, it doesn't matter whether that white noise comes from a £300 device or a phone app. So either they all work or none of them do.

I've had better experiences with actual EVP recording using my audio interface and some decent software. There's something about the deliberate process of setting up equipment, asking questions, recording in silence, and then listening back carefully that seems to yield more interesting results than asking an app a question and getting instant responses. The immediacy kills the whole thing for me.

Has anyone here actually recorded anything unexplainable on any of these apps? Not just pareidolia or coincidental sound patterns, but something genuinely anomalous? Genuinely curious because I've heard loads of anecdotes but no concrete examples.

The Spectral one sounds interesting from a technical standpoint because it claims to have filtering algorithms. That's at least trying to do something beyond just raw white noise. But I'd be curious about the validation behind their AI training data. How do they know what a 'spirit voice' sounds like well enough to train an algorithm to recognise it?
