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. ### 3/5 — Needs UI overhaul *2024-12-19* This app is wonderful, access to excellent music but the app is so buggy and disorganized. The user interface constantly moshes interface elements together making them impossible to accurately interact with them and it freezes up and consistently crashing or not playing many songs. There’s no way to save playlists you find or play all or shuffle from a playlist. These are all very essential elements to have a great music playback app. The app needs a focus on user friendliness and intuitive design. I otherwise love the idea of the app and hope it gains popularity because I sincerely appreciate being able to retune music I listen to, to whatever frequency I want. ### 4/5 — Been looking for.. Thank you. *2024-10-27* Would love to see offline listening capability for this app as well. Keep up the great work 💜 ### 3/5 — Not bad but needs more *2024-08-17, version 1.0.34* Good app but there’s SO MANY songs and artists that aren’t available ### 3/5 — Love the app but… *2024-07-18* One of my favorite apps, the updates are finicky tho, been have constant freezes since the last one. Still works but i have to restart the app often ### 4/5 — So far I like it. *2023-12-20, version 1.0.14* So far I like it. Will continue to explore. ### 3/5 — Love the concept *2023-08-01, version 1.0.6* I love the concept but it crashes immediately whenever I choose a song. ### 3/5 — App Crashes *2023-05-26* The app imported my songs but every time I try to play one it crashes. I love the idea of this app and I need this fixed! You got this developer!! **Developer response:** Please update to the latest version ### 5/5 — Recommend *2023-05-11* I found a lot of new artists and songs I like. Has lots of genres to choose from. The app is a great investment in your mental and emotional well-being. ### 5/5 — Really neat *2023-05-09* This app is super cool. Not only is it just a music app, which is necessary for car drives, you can adjust the frequencies! Sitting and playing with your songs and adjusting the frequencies to what fits your ears is something I never knew an app could offer. It helps a lot when it comes to a few songs I love, but some of the pitches were just too high and gave me sensory overload lol. I definitely recommend!! ## Most critical reviews (10 lowest-rated) ### 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 ### 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! ### 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. ### 1/5 — Wouldn’t Play *2025-06-06, version 1.0.43* I couldn’t get this app to actually play the music. It just sat there and did nothing when I clicked play. ### 1/5 — Unusable! *2025-05-20* Unfortunately this app is unable to properly retrieve songs from my library. The person I wrote told me they would fix it but 1 year later and still no improvement in sight. **Developer response:** Hi, can you please email hi@syqel.com we would be happy to help! ### 1/5 — Very limited features *2024-08-26, version 1.0.34* Only accesses certain songs from my library and just another company that makes you jump through hoops to get customer support! ### 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 ## Most praised reviews (10 highest-rated) ### 5/5 — Best app on the market! *2026-08-04* I'm enjoying it every single day. Thank you! ### 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 ### 5/5 — Thank you! *2024-12-05* I appreciate the developers of this app so much. You all rock! Once you hear music this way you can’t go back. 🤙🏻 ### 5/5 — Best music app ever *2024-08-07* so glad i finally found an app that i can change the frequency of the songggg🥳 ### 5/5 — I love this app!! *2024-07-26* I love this app. Such an amazing app. This is the only place I can go to be guaranteed to enjoy all my music at any frequency I want!! I hope this app stays here forever!! :) ### 5/5 — FINALLY! *2024-02-13* I’ve been looking for an app like this for ages. Any tuning is available at your finger tips. This app is useful in so many ways. Finally - the ultimate Frequency Music experience is here!! **Developer response:** Thank you so much! We appreciate your feedback! ### 5/5 — I love it! *2023-05-26* I love how you can change the frequency of each song! ### 5/5 — Love the experience *2023-05-24, version 1.0.5* I just love the experience that this app brings to table. You can connect it with your Apple Music library. You can play your own music through it. Super responsive UI. Sleek design. I love the dark theme. On top of everything, you can change the frequency to any music that you listen too. Rest it has all the bells and whistles any other high profile music players in market like pandora, Spotify. If you have music on your phone. This one is a must download. ### 5/5 — An app that provides a really good music experience *2023-05-23* I’ll admit it that the audio output is high quality, looking for new genres and switching between music is very effortless. Smooth modern looking layout and I know that this app will continue to make improvements because of what it’s already showing me. ### 5/5 — Cool app with nice vibes *2023-05-16* I enjoyed playing my music and loved the vibe of the app. It’s also super easy to use. Highly recommend. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
