Terms of use
Little Air is an iPhone app that shows air quality and helps you plan time outdoors. By using it you agree to these terms.
Little Air is made by Little Studio, the studio of Muaaz Saeed, who publishes it on the App Store (“we”). Last updated 22 October 2026.
The readings are indicative
Little Air reports the US Air Quality Index, computed from pollutant concentrations published by public monitoring networks and from atmospheric model forecasts. Two things follow from that, and they matter:
- A measured reading is as timely as its source. When a monitoring station publishes late, the app is late with it. Every reading in the app states how old it is, and that age is the honest one.
- A modelled estimate is not a measurement. Where no station covers a place, the app shows a model’s estimate for an area tens of kilometres across, and labels it as such. It is not an instrument reading at your location.
Air quality can change faster than any forecast. Use your own judgement.
Not medical advice
Little Air is not a medical device and does not provide medical advice. The guidance it shows is general information drawn from public air quality guidance. If you have a respiratory or cardiac condition, or any health concern about air quality, consult a qualified professional. Do not rely on this app for decisions about your health.
No warranty
The app and its data are provided as they are, without warranty of any kind. We do not guarantee that readings will be available, current, accurate or uninterrupted. Upstream data providers and networks can fail, and sometimes do.
Your account
An account is optional. If you create one, keep access to the Apple or Google account you signed in with, since that is how you get back in. You can sign out or delete your account from Settings at any time; deleting is permanent.
Acceptable use
- Do not attempt to disrupt, overload or reverse the service.
- Do not redistribute bulk air quality data obtained through the app. The underlying data belongs to its providers and carries their own licence terms.
- Do not use the app to present readings as regulatory or official measurements.
Changes and availability
These terms may change; the date above will change with them. Features may change, and the service may be interrupted or discontinued.
Limitation of liability
To the extent permitted by law, we are not liable for any loss or damage arising from your use of the app or from reliance on its readings.
