The problem
A dose taken wrong delivers less medicine to the lungs. Most patients get their technique checked once in a clinic, if ever, and never again.
“A clip-on sleeve that needs no charging or pairing, plus app feedback on every dose, is a smart, practical design.”
A clip-on sleeve for the inhaler you already use, and a phone app that checks how you took each dose and tells you what to fix.
Attach the lightweight AeroSleeve to your inhaler. It’s a passive accessory with nothing to turn on.
Set your phone down about 30 cm away and tap the circle in the app to start.
Keep your routine and follow your care team’s instructions. Your phone listens nearby and the app guides you through each step.
The app turns what it hears into clear, encouraging suggestions to try next time.
Tap to start
Set the phone down about 30 cm away. Tap the circle to start.
Scroll to follow the steps. Illustration of the app, which is in development.
Designed to flag common technique mistakes and explain the fix, instead of only logging that a dose happened.
No battery, no Bluetooth pairing, no second device. If the phone is nearby, it works.
Clamps to the outside of the inhaler body. Nothing changes about the medicine or how it is taken.

A friendly wellness app for adults, with a kids mode planned so children can practice good habits alongside a parent or caregiver.
We’re opening early conversations with clinics, health plans, community programs, and global-health teams who want to make inhaler technique easier to understand.

Aayush ChayanCo-founderI used to use a rescue inhaler. It was a miracle device: when I couldn’t breathe, it would open my airways for a bit and make the experience more bearable.
When I was younger, the one thing I remember feeling around this device was uncertainty.
As I grow older, I grow more and more certain that no child struggling to breathe should have to experience that uncertainty around their miracle device.

That’s why we’re building AeroSleeve.
Our mission is to make inhaler technique easier to understand through accessible technology and actionable feedback.
AeroSleeve is in development. We’ll share what we learn as we go.
Join the waitlist for updates as AeroSleeve takes shape. Families, clinicians, researchers, and partners are all welcome.
Researchers have documented this for decades. A review of 144 studies found no significant improvement over time.[1]
Pooled results from studies of 54,354 people with asthma or COPD, observed 1975–2014.[1]
AeroSleeve gives people feedback on technique every time they use their inhaler, with a record a clinician can review.
The sleeve is a single part with no electronics, and the app runs on a phone the patient already owns.
Most inhaler doses are wasted by technique, not by the medicine. Every inhaler already makes a distinct sound when you use it. AeroSleeve gives your phone a clean, repeatable way to hear it and turn it into coaching.
A standard metered-dose inhaler, straight from the pharmacy. The medicine, the mouthpiece and the air path are untouched.
Clips to the outside of the inhaler body, never the mouthpiece. Two sealed cavities shape the sound at the moment of the dose so the phone hears it consistently.
Set down nearby, not docked or paired. The app listens for the dose and your breathing, then explains what to fix.
Early results from our own bench and live recordings of real inhaler doses, using an iPhone about 30 cm away.
What this is, and isn't. One person, one phone, inhaler cupped in a hand to mimic a mouth, and thresholds tuned on these same recordings. It shows the signal is there; it is not yet validated across phones, people and rooms. Testing on placebo inhalers with new users is next.
Sleeve CAD, 3D-printed prototypes, and a working phone app that guides each step.
Dose and exhale detection running on real recordings, including live in the app.
More phones, more people and rooms, on placebo and trainer inhalers.
Technique coaching tested with a clinical partner, with a clinician-facing record.
Other approaches count puffs, coach in the moment, or live in the clinic. AeroSleeve is built to do all three jobs without the cost of electronics.
