FAQ
What is Entrain and what does it do?
Entrain is a brainwave entrainment app that uses precisely tuned audio frequencies to gently influence your brainwaves. It aims to promote deep sleep, calm focus, and enhanced meditation states.
How does Entrain work?
It plays two slightly different tones, one in each ear, creating a perceived 'beat' that your brain synchronizes with. This frequency-following response can nudge brainwaves towards desired states like delta for sleep or alpha for focus.
What makes Entrain different from other relaxation apps?
Entrain offers precise frequency control, multiple entrainment modes (binaural, isochronic, monaural), descent programs to transition between states, and mixable synthesized sound beds, unlike generic spa music apps.
Does Entrain require headphones?
For the best results with binaural beats, headphones are recommended to ensure the distinct tones are delivered to each ear. However, it also offers isochronic and monaural modes that can work on speakers.
Can I use Entrain offline?
Yes, Entrain works fully offline as the audio is generated on your device. No account is required to use its features.
What are the subscription options for Entrain Pro?
Entrain Pro offers monthly ($6.99/month) and annual ($39.99/year) subscriptions. The annual plan includes a 7-day free trial.
How do I cancel my Entrain Pro subscription?
You can manage or cancel your subscription anytime through your App Store account settings. Cancellations must be made at least 24 hours before the end of the current subscription period.
Is Entrain suitable for children?
Entrain has an age rating of 4+, making it suitable for a wide range of users. It is designed for relaxation, focus, and meditation support and is not a medical device.
