FAQ
What is Amplii?
Amplii generates binaural beats, which are auditory illusions created by playing two slightly different frequencies, one to each ear. This is designed to influence brainwave activity for states like focus, meditation, or sleep. The app features dynamic 'arcs' that shift frequencies over time.
Does Amplii require headphones?
Yes, headphones are required for Amplii to function correctly. The binaural beat effect relies on the two distinct tones reaching each ear separately. The app checks for headphone connection before starting a session.
What are the free modes in Amplii?
Amplii offers four free modes: Meditate, Focus, Energy, and Sleep. Each mode has a default length but can be adjusted from five minutes to two hours. A pink noise bed can also be switched on under any session.
What does the one-time purchase in Amplii unlock?
The single purchase unlocks full control over the binaural beat arcs. This includes setting custom start, hold, and return frequencies, adjusting ramp timing, assigning ear tones, and tuning the underlying tone pitch.
Is Amplii a subscription app?
No, Amplii is not a subscription app. The unlock is a one-time purchase that is tied to your Apple Account and will restore if you delete and reinstall the app or switch to a new phone.
Does Amplii collect user data?
No, Amplii is designed with privacy in mind. It does not require an account, sign-in, or collect analytics. Your modes and settings remain on your device and are deleted with the app.
How often is Amplii updated?
The latest version of Amplii is 2.0, which was last updated on October 23, 2026. While specific update frequency isn't detailed, the app has seen recent updates.
Is Amplii suitable for all ages?
