Two minutes. Science-backed. The neural reset protocol used by executives, surgeons and founders to enter every high-stakes moment at peak cognitive state.
Between works in three stages: you choose the moment you're in, the protocol resets your nervous system, and you step into whatever's next at peak state.
Tap the situation you're in — before a meeting, mid-afternoon slump, after a hard call. Between selects the exact protocol matched to your nervous system state right now.
The breathing orb guides your inhale, hold and exhale with precision timing. No thinking required — you simply breathe with it. The rAF-driven animation is frame-perfect at 60fps.
Your cortisol drops, HRV rises and prefrontal cortex engagement increases. You walk into the meeting, call or deep work block as the sharpest version of yourself.
Each card maps to a scientifically validated breathing protocol. Signed-in users go straight to their session — no menus, no friction.
Every Between protocol is engineered from peer-reviewed research in respiratory physiology, neuroscience and cognitive performance. Here's exactly what happens inside your brain and body.
Controlled breathing directly stimulates the vagus nerve — the primary pathway of the parasympathetic nervous system. Exhale-dominant patterns (longer out than in) activate the "brake pedal" on your stress response within 60 seconds, measurably dropping heart rate and cortisol.
Heart Rate Variability coherence — achieved through the 5·5 resonance frequency breathing — synchronises oscillations between the heart and prefrontal cortex. This state is directly correlated with improved decision-making, emotional regulation and working memory by up to 25%.
The HPA axis — hypothalamus, pituitary, adrenal gland — regulates cortisol release. Sustained diaphragmatic breathing reduces HPA axis reactivity, lowering cortisol in saliva by a measured 18% after a single session. The effect compounds with daily practice over 14 days.
"I run Between before every board meeting. Two minutes and I walk in as the calmest person in the room. My direct reports noticed within the first week."
"It replaced my pre-surgery ritual entirely. I'm sharper, steadier, more present in theatre. My team noticed before I even told them what I was doing."
"Energy Spike at 3pm instead of a double espresso. My sustained focus at 4pm now beats my focus at 9am used to be. No jitters, no crash, no dependency."
Between's protocol design draws on research from Stanford, HeartMath Institute, the American Institute of Stress, and the Polyvagal Institute. Every breathing pattern, phase duration and cycle count is calibrated to the published research — not guesswork.
