The Creator is incredible. I can set the exact frequency I want, layer ambient sounds, and bio-resonance shows me in real-time what works. No other app comes close.

All Features
A complete frequency lab.
Six core functions that set SINE apart from every other meditation app.
🎵
Any Frequency. Generated in Real-Time.
Set any base frequency from 20 Hz to 20 kHz. Choose a binaural beat from 0.5 to 100 Hz. Everything is computed live: 44,100 samples per second, 0.01 Hz precision. What you set is exactly what your brain receives.
Frequency Engine🤖
Describe Your Mood. Get Your Frequency.
Tell the AI 'I'm stressed and can't sleep', and it analyzes your goal and builds a personalized session in seconds. Optimal frequency combination, matching ambient sounds, the right duration. No prior knowledge needed.
AI❤️
See Which Frequencies Calm Your Nervous System.
Connect your Apple Watch. See heart rate and HRV in real-time during meditation. After each session: which frequencies calmed your nervous system, how much your HRV increased, and how your body responded to different settings.
Bio-Resonance♥Resonance
🎹
Program Frequency Journeys Over Time.
Start at 10 Hz alpha for relaxation, glide to 4 Hz theta for deep meditation after 10 minutes, and end at 2 Hz delta for sleep. Full-state snapshots store every parameter. The transition is smooth and precise.
Sequencer🌊
46 Sounds. All Tuned to 432 Hz.
Rain, ocean, forest, fire, and instruments. 46 high-quality WAV files with 3D spatial audio. Position sounds in space, control direction, fill the room with reverb. Everything can be layered with frequencies and noise.
Ambient Sounds👥

What Users Are Saying
I told the AI: 'I'm exhausted but can't sleep.' In 5 seconds I had a session with delta beats, brown noise, and ocean sounds. I was out in 10 minutes.
— - Michael K.
AI SessionsThe sequencer is genius. I program a 30-minute journey: alpha to wind down, theta for meditation, delta to fall asleep. Like an automatic frequency therapy.

FAQ
Frequently Asked Questions
How is SINE different from Calm or Headspace?
Calm and Headspace are guided meditation apps. You listen to pre-recorded instructions. SINE is a frequency instrument: you create your own binaural beats and soundscapes in real-time, program frequency journeys with the sequencer, and bio-resonance tracking measures the effect on your body. Instead of passive listening, you actively build your practice.
Do I need headphones?
For binaural beats: yes. Two slightly different tones in each ear create the effect. This only works with stereo headphones. For ambient sounds and noise: headphones are recommended for the best experience but not strictly required. Any stereo headphones work, expensive ones aren't necessary.
Is there a free version?
Yes. The free version gives you 2 AI tokens and 5 creator sessions (25 minutes each). Premium starts with a 7-day free trial, no credit card required. Premium includes 20+ AI tokens, unlimited creator access, bio-resonance tracking, and community features.
What devices does SINE work on?
SINE is currently available as an iOS app for iPhone. Apple Watch is supported for bio-resonance tracking. Android and a web app are on the roadmap. You can use the web version at sine-immersive.com for subscription management and blog content.
