Fall asleep in 10 minutes.
$8.99 · In‑App Purchases · Designed for iPad. Not verified for macOS.
Place your phone on the nightstand. Follow the glow — or close your eyes and let gentle haptics pace your breath. Fall asleep in 10 minutes. No subscription.
zzZ is a calm, ambient breathing light for the end of the day. No account. No subscription. No notifications. Place your iPhone or iPad on the nightstand, follow the glow, and let your breath slow to the rhythm that research has linked to better sleep.
THE METHOD
Slow-paced breathing at around six cycles per minute — a rate known as "resonance breathing" — is associated in published studies with reduced sleep-onset latency, fewer nighttime awakenings, and greater parasympathetic (rest-and-digest) activity (Laborde et al., 2022; Hamasaki, 2020). A longer exhale than inhale is linked to increased vagal tone and heart-rate variability (Laborde et al., 2024; Jerath et al., 2006).
zzZ starts at a comfortable pace (around ten breaths per minute) and gently eases you down to roughly six over two to three minutes — the same descent pattern used in heart-rate-variability biofeedback protocols. You simply follow the breathing orb, or close your eyes and feel the gentle haptic swell on each inhale and exhale.
DESIGNED FOR THE NIGHTSTAND
- Eyes-closed mode — a gentle haptic pulse marks every inhale and exhale, so you can put the phone face-down and let the rhythm do the rest
- Full-screen breath orb — no menus, no chrome, no ads
- Melatonin-friendly Red Night theme (plus Warm Amber, Moonglow, Aurora)
- Optional ambient bed (pink noise, brown noise, soft rain, or silent)
- Optional breath chime cues
- Works beautifully on iPad in landscape — a true bedside breathing lamp
PRESETS
- Sleep Descent — guided 10 → 6 BPM wind-down (default)
- Deep Resonance — steady 5.5 BPM, vagal activation
- 4-7-8 — the Weil technique
- Box — even four-count for calm focus
