Thetaloom
See the Hz in each ear
L 200 Hz and R 210 Hz make a 10 Hz alpha beat. The ring shows both tones and the beat while you listen. Audio is generated on your device in real time, not played from compressed loops.

FAQ
Good questions.
Do binaural beats need headphones?
Yes. A binaural beat appears when each ear hears a slightly different tone, so you need stereo headphones or earbuds. Isochronic tones and noise also work on a speaker.
Is Thetaloom medical?
No. Thetaloom is for relaxation and focus. It is not a medical device and does not diagnose, treat or cure any condition. If you have a health concern, talk to a professional. Check with your doctor first if you have epilepsy or a seizure history.
Does it work offline?
Yes. Tones and noise are generated on your device, so they work with no connection. Scenes and sound beds are downloaded once and then play offline.
Can I cancel anytime?
Yes. Manage or cancel in your Apple ID settings (iOS) or Google Play subscriptions (Android). There is no account with us to close.
Do I need an account?
No. Open the app and press play.
Which languages are supported?
46, including English, Turkish, German, French, Spanish, Japanese and Arabic.
Is this the same app as BrainSync?
Yes. BrainSync is now Thetaloom. Your existing app, purchases and history stay as they are.
