The problem
Up to 90%[2] of people use their inhaler wrong. Almost no one checks.
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.
Only about 1 in 3 people with asthma or COPD have fully correct inhaler technique.
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]
Built for the people who use inhalers, and the people who support them.
An app everyone can use.
A friendly wellness app for adults, with a kids mode planned so children can practice good habits alongside a parent or caregiver.
- Simple sleeve, no batteries or charging
- Plain-language tips after each use
- Kids mode for younger users (planned)
Help your community build better habits.
We’re opening early conversations with clinics, health plans, community programs, and global-health teams who want to make inhaler technique easier to understand.
- Clinics and pharmacies
- Health plans and community programs
- Global-health and research partners
Simple on purpose.

Attach the lightweight AeroSleeve to your inhaler. It’s a passive accessory with nothing to turn on.
Use your inhaler as usual
Keep your routine and follow your care team’s instructions. Your phone listens nearby.

The app turns what it hears into clear, encouraging suggestions to try next time.
Our mission is to make inhaler technique easier to understand through accessible technology and actionable feedback.
- Patient-centered design
- Accessibility and affordability
- Evidence-based engineering
- Simplicity and usability

AeroSleeve is in development. We’ll share what we learn as we go.

One plastic part. Your phone does the rest.
The sleeve is a single part with no electronics, and the app runs on a phone the patient already owns.
- Fits the inhaler you use
- Clamps to the outside of the inhaler body. Nothing changes about the medicine or how it's taken.
- Checks how, not just when
- Designed to flag common technique mistakes and explain the fix, instead of only logging that a dose happened.
- Nothing to charge
- No battery, no Bluetooth pairing, no second device. If the phone is nearby, it works.
How it compares
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.
| AeroSleeve | Electronic sensor caps | Coaching whistles | Clinic recording devices | |
|---|---|---|---|---|
| Electronics or batteries | None | Yes, charge and pair | None | Dedicated device |
| Checks technique, not just timing | Yes | Mostly logs when | Live cue only | Yes |
| Record your clinician can see | Yes | Yes | No | Yes |
| Made for everyday use at home | Yes | Yes | Yes | No |
| Extra hardware to buy | None, uses your phone | One per inhaler | None | Recorder |
| Price | Target under $25 | Priced like electronics | Low | High |
AeroSleeve is in development. Categories describe typical products in each class; features vary by model. AeroSleeve is a coaching and wellness tool, not a diagnostic device.

Drag to rotate
Illustrative form
A simplified shape. Internal features of the production design are left out.
Air path untouched
No part of the sleeve crosses the mouthpiece, the spray, or the canister. We check this on every design iteration.
Cheap to make
One part, no assembly, no electronics. Built to be molded at volume.
