Breathe reads airway narrowing in real time — a gentle wrist tap that says step away from the trigger before the tightness arrives.
Your Asthma Management Audit
Scroll through. Answer quietly. Watch the gaps fill.
Most people with asthma carry a mental list: dust, cold air, stress. But correlation isn't causation, and guessing costs you avoidable exposures every single week.
Without objective data, you're managing symptoms after they appear, not preventing the exposure that caused them. The average asthmatic misidentifies at least two triggers.
Breathe tracks this
Breathe cross-references your FEV1 readings with environmental sensors, location data, and time patterns to surface your actual triggers — ranked by impact, confirmed by repetition.
Peak-flow diaries are the gold standard your pulmonologist asks for. They're also the thing nobody actually does between appointments — including night-shift nurses who know better.
Manual peak-flow logging has a 74% non-compliance rate. The data your doctor makes decisions from is often incomplete, inconsistent, or fabricated under pressure.
Breathe tracks this
Breathe estimates your forced expiratory volume every 90 seconds, passively, without blowing into anything. Your pulmonologist sees a 90-day trend line, not a 3-day diary you filled in the waiting room.
Children can't reliably report early symptoms. They push through chest tightness at recess. They wake at 3 AM struggling. You find out when it's already a rescue-inhaler moment.
Nocturnal asthma causes more ER visits than any other presentation — yet it's the least monitored, because it happens when everyone is asleep and no one is logging.
Breathe tracks this
Breathe monitors airway resistance through sleep cycles, flagging the 2–4 AM narrowing window that precedes 60% of pediatric emergency presentations. A quiet buzz on your wrist before the coughing starts.

The Checklist, Completed
Breathe cross-references FEV1 with air quality, pollen, location, and time-of-day patterns. After two weeks, your personalized trigger map is more accurate than a decade of guessing.
Passive estimation every 90 seconds. No blowing required.

Monitors airway resistance through all sleep stages. Alerts caregiver before the coughing starts.
REM · Deep · Light cycles monitored
A specific haptic pattern — not a buzz, a tap — that means step away now.
Trigger Detected
Step away · FEV1 declining
90-day FEV1 trend charts, trigger correlation matrices, and nocturnal event logs — formatted exactly as your specialist needs them. No more filling in diaries in the waiting room.

"My son had three nighttime attacks in two months before we got Breathe. The first time it buzzed me awake at 2:47 AM — his FEV1 was already dropping. We used his spacer. He never woke up. That's the first time I slept through a whole night in four years."

"I've been managing my own asthma for eleven years. I know the theory. I still never logged consistently. Breathe just does it. My pulmonologist saw my 90-day chart at our last appointment and said it was the best data she'd ever received from a patient. I didn't do anything differently — the device did."

"Mile nine used to be where my chest would tighten and I'd have to decide: push through or stop. I could never prove it to my sports medicine doctor because by the time I was in the office, everything looked fine. Breathe caught the pattern — cold air + pace over 8.2 mph. Now I know. I train around it instead of into it."
