Track your breathing rate and measure your lactate threshold with lab accuracy using just your earphones*.
Completely free for Android.
BreezeLabs uses proprietary AI to turn your earphones’ microphone into a clinical-grade sensor. We track what other apps ignore: your breathing patterns.
Lactate Threshold: Pinpoint your peak performance zones without expensive blood tests.
Breathing Trends: Track your respiratory rate over time to improve performance.
100% Free: Professional-grade sports science at no cost
*To ensure lab-level accuracy, the app is currently compatible with Shokz (OpenMove, OpenRun, OpenRun Pro, OpenSwim) and Redmi Buds 6 Active (retail price below 20 USD) earphones. More devices are being added.
