Sleep Tuning

About this app

Sleep Tuning helps you fall asleep faster and sleep more deeply using personalized acoustic neuromodulation — sound patterns scientifically designed to guide your brain through natural sleep stages.

HOW IT WORKS

Sleep Tuning generates real-time audio that gently synchronizes with your brain's sleep rhythms. Unlike white noise apps or sleep music, Sleep Tuning uses amplitude-modulated sound at frequencies that mirror natural brainwave patterns during the transition from wakefulness to deep sleep.

For users with a compatible BCI (brain-computer interface) EEG device, Sleep Tuning goes further: it reads your brainwaves in real time and adapts its acoustic output to your individual sleep physiology — a closed-loop system that responds to you, not just plays at you.

9 SLEEP PRODUCTS, ONE APP

Open-loop products (no device needed):
- Quick Sleep — Fall asleep faster with harmonic carrier tones that eliminate mechanical noise
- Relax Sleep — 440Hz carrier fades gradually into pure pink noise, creating a calming journey from tension to rest
- Night Owl Sleep — Pink noise blended with gentle rain sounds for those who are tired but can't switch off
- Calm — Mindful relaxation with singing-bowl-inspired tones
- NapBoost — A focused 20-minute power nap session
- Circadian — 40-minute rhythm reset for jet lag or irregular schedules

Closed-loop products (compatible BCI device required):
- Deep Relax Sleep ★ Recommended — For anxious or overactive minds. Starts with strong tonal anchoring, gradually dissolves into pure ambient sound, and waits for genuine relaxation before transitioning to deep sleep enhancement
- Deep Quick Sleep — Warm five-tone harmony wraps around breathing-rate modulation for rapid sleep onset
- Deep Night Owl Sleep — Immersive rain-at-night soundscape with ultra-gentle modulation for the already-exhausted

WHAT MAKES SLEEP TUNING DIFFERENT

Personalized, not generic. Each closed-loop product begins with a handoff stage tailored to your sleep style — then seamlessly transitions to cycle-aware deep sleep enhancement powered by real-time EEG analysis.

Sound, not medication. Sleep Tuning is a non-invasive acoustic wellness tool. It does not diagnose, treat, cure, or prevent any disease.

Private by design. EEG data is encrypted end-to-end, identified only by anonymous user IDs, and automatically anonymized after 90 days. We never share your brain data with third parties. See our full privacy policy at aikalab.se/privacy.

Free to use. All products are currently free. We believe you should experience the full value before we ever ask you to pay.

ABOUT THE TECHNOLOGY

Sleep Tuning is built by Aika Lab, a Swedish neurotechnology company specializing in acoustic neuromodulation. Our closed-loop engine samples EEG at 250Hz, detects sleep stages in real time, and delivers phase-locked acoustic stimulation with less than 50ms latency via Bluetooth Low Energy.

The science behind Sleep Tuning draws on published research in closed-loop acoustic stimulation (CLAS) for slow-wave sleep enhancement — a field with growing evidence for non-invasive sleep quality improvement.

REQUIREMENTS

- Any Android phone (Android 8.0+) for open-loop products
- A compatible Flexolink BCI EEG headset for closed-loop products
- Headphones or pillow speakers recommended for best experience
