This is a powerful pairing! Once connected, Halo’s discreet sensor array automatically detects when you start breathing and then syncs your breathing data with the app. An inhale/exhale LED ring indicates breath rate while its intelligent capture supports real-time or background passive modes. The personal dashboard shows real-time protection levels and tracks breathing by activity and location. Over time, it gets smarter if you opt in to share your modes of transport, routing and breathing behavior. This is one of the respiratory devices that work with Apple HealthKit, so you can track your breathing in iOS.
