Answers to the things people ask most, and a real address to write to.
Does ZenninOut need an internet connection?
No. Every sound is generated on your device as it plays, so the app works exactly the same in airplane mode, on a flight or underground. There is nothing to download.
How much does it cost? Is there a trial?
ZenninOut Pro is a subscription of $4.99 per month with no free trial — a single plan that includes every session, sound and study; nothing inside is locked and there are no ads. Payment goes through your Apple ID and renews automatically unless cancelled at least 24 hours before the period ends. Manage or cancel in Settings › Apple ID › Subscriptions; cancelling keeps access until the end of the paid period.
How do I change the language?
Journey › Settings › Language. The whole app switches immediately, including the onboarding. 108 languages are offered and 35 are translated in full; the rest fall back to English where a translation is missing.
Audio stops when I lock the screen.
It should not — ZenninOut plays in the background. If it stops, check that iOS Settings › Screen Time or a Focus mode is not suspending the app, and that Low Power Mode is off, as it can be aggressive about background audio.
Can I use it with headphones and Bluetooth?
Yes. Binaural beats specifically require stereo headphones to work at all, since the effect comes from a different frequency reaching each ear. Bluetooth headphones add a small delay that does not affect them.
How do I connect Apple Health?
Journey › Settings › Apple Health. Granting access lets the app write your sessions as mindful minutes and read heart-rate variability and resting heart rate. It is entirely optional and nothing else in the app depends on it.
How do I delete my data?
Journey › Settings › Your data › Delete everything. That removes your history, moods, journal, favourites and saved mixes immediately. Deleting the app does the same.
Is any of this medical advice?
No. ZenninOut is a tool for everyday calm and attention. The Science tab summarises published research and links to the source, but that is education, not treatment. If you are struggling with your mental health, please talk to a clinician.
