Pure Phase vs Isla

Pure Phase uses synchronized light, sound, and breath to guide you into focused, calm, or sleep states — without subscriptions, accounts, narration, or bloat. Tap to begin. Hold to tune. That's the whole interface. THREE SCIENCE-GROUNDED STATES FOCUS — 40Hz gamma frequency, synchronized light and isochronic audio. Associated with peak mental clarity. The subject of ongoing clinical research at MIT and elsewhere. CALM — 10Hz alpha frequency. One of the most consistently documented frequencies in relaxation and stress research. Ideal for unwinding, creative work, or transition between tasks. SLEEP — 2Hz delta frequency. Use with eyes closed and torch enabled. The flashlight pulses at the session frequency through your eyelids — no screen required. BREATHE — GUIDED BREATHWORK A fourth mode with no flicker — just a breathing ring that expands and contracts to pace your breath. Choose from Coherence (6 breaths per minute, the HRV resonance frequency), 4-7-8, Box breathing, or Slow Wave. Or build your own pattern in Advanced settings. ISOCHRONIC AUDIO A warm audible carrier tone pulses at the brainwave frequency, synchronized frame-by-frame with the visual flicker. Underneath, a procedurally generated ambient texture — pink noise, brown noise, or sustained drone — provides continuity and masks environmental sound. Everything is generated on-device. No audio files. DRIFT & BLOOM New psychoacoustic modes for headphones. Three synthesis layers create auditory depth and slow movement through pure tones — a breathing carrier, a drifting stereo field, and optional harmonic shimmer. DRIFT pairs them with a pure black canvas. BLOOM pairs them with a slow generative visual field that breathes and shifts color in sync with the audio. Non-stroboscopic — accessible to anyone who can't tolerate the entrainment modes. ADVANCED For users who know what they want: Theta, SMR, PRISM, and Void states, a custom Hz slider from 0.5 to 40Hz, custom breath timing with independent inhale, hold, and exhale controls, and carrier frequency selection. Clearly labeled as exploratory. PURE PHASE IS FREE No subscription. No account. No guided narration. No content library. No streak tracking. No ads. No data collection of any kind. Everything runs on your device. Pure Phase uses rapid rhythmic light pulses. Do not use if you are photosensitive or have a history of epilepsy or seizure disorders. Always use in a safe, seated, stationary environment. Not a medical device.

Isla is your island of calm — a gentle, private way to settle your nervous system in about three minutes, whenever life feels like too much. No long courses. No streaks to keep. No pressure.

HOW IT WORKS • Check in with how you feel, right now • Follow a calm ~3-minute somatic or breathing practice, guided by a soft voice and a breathing orb • Afterwards, notice how you feel — and let Isla quietly learn what helps you PERSONALIZED, PRIVATELY Isla uses on-device intelligence to choose the right practice and frame it warmly for you — entirely on your iPhone. Nothing you share leaves your device. There are no accounts and no third-party tracking, and your reflections are created privately on your iPhone. You can clear everything anytime.
