Which one should I use?
If you have headphones, binaural beats give a soft, immersive phantom beat. If you're on a speaker — a bedside speaker, your laptop, the car — use isochronic tones, whose pulse survives in open air. Both target the same brainwave bands; they're just two ways to deliver the rhythm. Not sure? See binaural vs. isochronic.
What you can do for free
- Play live binaural beats or isochronic tones in your browser
- Choose delta, theta, alpha, beta, or gamma presets
- Fine-tune the beat or pulse frequency and volume
- Add a brown-noise layer (isochronic)
- Sessions up to 30 minutes — no account, nothing stored
What the app adds
The free player is a genuine taste of Entrain. The app removes the session cap and adds 20 tuned presets, saved custom frequencies, brown/pink/rain/ocean ambient layers, a sleep timer up to 8 hours, background and lock-screen playback, session history and streaks, and native apps for iPhone, iPad, Apple Watch, and Mac — all fully offline. Android is coming soon.
Tip: The player works on phones too. On iPhone, add it to your Home Screen for a quick-launch button. For all-night sleep use and background playback, the native app is the better fit.
