Sound, engineered for your brain. GlymphRest™ plays precision binaural audio tuned to the state you want — deep sleep, sharp focus, calm, creativity, and more. You pick the outcome; it handles the science. GlymphRest™ is a sound-first wellness app built on published research into how the brain responds to sound. Choose a goal, put on your headphones, and press play — each session pairs carefully tuned binaural beats with a curated ambient soundscape, so you can settle into the state you’re after. ONE TAP, OR FULL CONTROL One-Tap Mode: turn the dial to your goal and tap — a curated session starts instantly, no setup. Full Mix Mode: every preset, sound, timer and setting, yours to shape. Switch between the two anytime from Home. NINE OUTCOME PACKS Deep Sleep — delta-range sessions for the deepest, most restorative part of the night. Focus & Alertness — beta sessions for analytical work, study, and a caffeine-free morning lift. Meditation — alpha-to-theta sessions that support the shift from alert calm into stillness. Stress Relief — including Breathe, a guided ~6-breaths-a-minute session grounded in HRV research. Creativity — alpha sessions designed to support open, idea-generating thinking. Rest & Restore — a daytime ladder from a waking reset to a fog-free power nap. Peak Performance — tune your arousal to the sweet spot before you perform. Memory & Learning — a study cycle: get receptive, encode, then let it settle. Ambient Sounds — play rain, ocean, forest, wind chimes, soft wind and more on their own. BUILT WITH SCIENTIFIC INTEGRITY Every claim in GlymphRest™ stays close to publicly available research. We use supportive language — “designed to support,” “associated with” — never miracle cures. Each pack includes a “Know the Science” panel so you can see exactly what the research does and doesn’t say. THOUGHTFUL DETAILS ▸ Headphone-first binaural audio — with an honest speaker mode that plays an audible pulsed tone when you’re not wearing headphones. ▸ A curated ambient mix for every pack — layer in rain, ocean, café, forest, wind chimes and more. ▸ Session presets tuned to the specific brainwave range research maps to each state. ▸ Five gemstone color palettes — Lapis, Moonstone, Turquoise, Sunstone and Opal — free on every plan, and the whole app follows your choice. ▸ Haptic feedback you can tune from subtle to firm, or turn off. ▸ Private by design — no tracking, no ads, no data collection. Your progress stays in your own iCloud. SUBSCRIPTION GlymphRest™ offers Basic, Premium, and Advanced tiers with monthly, annual, and lifetime options.
