Breathing Index is a personal air index that learns your triggers from your own breathing logs. It compares today's conditions with your recorded history and rates the day on a four-level scale from 1 (Easy) to 4 (Dangerous). It is aimed at people who want to track how air conditions affect their breathing over time. You keep a log of your breathing, and the app uses those entries to show how the current day compares with what you have recorded before.
Log your breathing and see how today's air compares on a four-level scale.
