Check inhaler technique with the phone you already have.
AeroSleeve is a clip-on sleeve for metered-dose inhalers. Paired with a phone app, it points out what went wrong with each dose. Nothing to charge, nothing to pair.
Illustrative form · drag to rotate
Between 50 and 90% of people who use inhalers make at least one critical technique error.
Technique gets checked in the clinic, if it gets checked at all: someone watches you take a dose and corrects you. Most patients never get that second look, and a dose taken wrong delivers less medicine to the lungs.
Existing tools either count puffs without knowing how they were taken, or coach in the moment and keep no record a clinician can review.

Recognition
“A clip-on sleeve that needs no charging or pairing, plus app feedback on every dose, is a smart, practical design.”

See it on a real inhaler.
We'll bring a printed sleeve and the app, and walk through what it catches today and what's still in testing.
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.

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.
