How to cancel HZP (Hertz Player) subscription ⁉️

User reviews

Best app on the market!

I'm enjoying it every single day. Thank you!

WARNING! ⚠️

"Free trial" offers act as deceptive subscription traps. I was automatically charged $19.99 immediately after signing up and faced difficulties canceling auto-renewal. The developer is fully aware of these ongoing issues but does not care to resolve them. Stay away from this app!

Buggy App- Raising prices?

The app never worked well to begin with but it worked fine enough. now they raised the prices on the features and bugs continue to increase

Scam

You can’t even change a single frequency without having to pay for a monthly subscription! It’s set to 440hz and if you want to change it to 432hz as advertised you are forced to pay

They took away Apple Music support

The Solfeggio does its job really nice overall, however the support for Apple Music has disappeared and makes it harder to meditate to my music library in some cases . Add back support and fix the problem with one song at a time being played when using Apple Music and I’ll change my review to a higher rating again
