Common questions
I bought the Full Concert and it is not unlocked
Open the unlock panel and tap Restore purchase. The Full Concert is a one-time purchase tied to your Apple Account, so it restores on any device signed in to the same account, and it is shared through Family Sharing.
The unlock button says the store is unavailable
That means the app could not reach the App Store — usually a brief network problem. Tap Try again. The free scores keep playing regardless, and nothing is lost.
What is free?
Moonlight · Presto, Für Elise, the Classical reading and the EDM remix are free forever, with no time limit and no ads. The Full Concert unlocks the rest in one purchase. There is no subscription.
There is no sound
Check the silent switch and the volume, then make sure the app is not muted — Mute is on the wheel’s main menu and on the player deck. Audio starts only after you press play; that is deliberate, because browsers and iOS both require a real tap before any sound.
Stations will not play
Stations stream public-domain recordings from the Internet Archive, so they are the one part of the app that needs a network connection. Everything else — the written scores, your own songs, the whole simulation — runs offline.
Listen Mode and the microphone
Listen Mode makes the fluid react to music playing around you. The microphone feeds the audio analyser and nothing else: nothing is recorded, stored or sent anywhere, and turning Listen Mode off releases the microphone. Declining the permission changes nothing else in the app.
Where did my recording go?
Recordings are handed to the iOS share sheet when they finish, so you choose where they land — Save to Files, Save to Photos, AirDrop or Messages.
Can I try it before buying?
Yes. The whole thing runs free in a browser at djenterprises.ai/fluid-sonata — no install and no account.
Privacy
No account, no analytics, no third-party SDKs, no tracking. Nothing you do in the app is collected. Full details in the privacy policy.
