AirGuard

Delhi's air changes by the hour and by the street. Your commute can too.

Pick a trip. AirGuard checks each route, 200 metres at a time, for every departure in the next few hours, and shows you where the smoke thins out.

How AirGuard reads a route

The same ride as above, leaving now. Numbers on the map match the notes.

Honest about what it knows

Delhi has a few dozen reference monitors for a city of more than twenty million people. Most of a route is far from any of them, so AirGuard says how sure it is every time.

AirGuard won't:

  • Show a number without its range.Every exposure figure comes with a forecast range and a confidence score.
  • Call the air “safe”.It tells you which option means less exposure, never that some amount is fine.
  • Compare cycling with driving.Breathing rates differ by mode, so options are only compared within one way of travelling.
  • Invent a number.The assistant can only repeat numbers its tools returned; anything else is caught and replaced.
  • Hide a delayed feed.When a station's data runs late, its value is marked as a model estimate.
  • Give medical advice.It's exposure guidance. If air pollution affects your health, talk to a doctor.
