Thank you! ### 1/5 — WARNING! ⚠️ *2026-06-10, version 2.1.0* "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! ### 1/5 — Buggy App- Raising prices? *2026-05-27, version 2.1.0* 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 ### 1/5 — Scam *2025-12-31* 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 ### 2/5 — They took away Apple Music support *2025-12-22* 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 ### 5/5 — It doesn’t work *2025-11-11* Downloaded the app, but it just gets stuck in the “select music” section. The “continue” button doesn’t respond ### 1/5 — Data harvesters?? *2025-11-05, version 2.0.3* DOESNT WORK AT ALL. After u register and give them access to your phone AND DATA, you’re done. That’s as far as it’d let me go. Classic data harvesting tactic! Dont waste your time! ### 3/5 — Simply wouldn’t work *2025-10-29* This simply did not work for me. I spent hours trying to get this app to sync to Apple Music, with no success. After finally getting a couple songs to show up in the app, they wouldn’t play when I clicked on them. The website didn’t have any tutorials, as far as I could see. $10 to subscribe to this app and another $10 to subscribe to Apple Music was not worth it. Back to Pandora for me. Three stars for a really cool idea, though. Hopefully it works for others. ### 1/5 — Buggy *2025-10-19, version 2.0.1* This app is a great concept but too buggy. The t crashes and doesn’t work. ### 1/5 — B.S. *2025-08-30, version 1.0.43* Doesn’t actually change the frequency, I teated it with my spectrum analyzer. ## Frequently asked questions about HZP (Hertz Player) ### What does HZP do?
