AYO BT+
AYO BT+ is a unique breathing measurement respirator series invented for breathing training and monitoring for asthmatics, sports, and general health.
About the project
What AYO BT+ does
AYO BT+ is the companion app for a modular breathing measurement and training device designed for people with asthma, athletes, and anyone interested in general respiratory health. It combines breathing measurement, diaphragmatic breathing training, and spirometry testing in one product. Users can see real-time breathing data, practice healthier breathing patterns, and share measured insights with trainers or clinicians remotely.
Karma Technolabs developed the AYO BT+ app for Android and iOS with Flutter and a Node.js backend. The core engineering challenge was hardware integration: the app pairs with the device over Bluetooth Low Energy and captures breathing metrics in real time, then turns them into waveforms, dashboards, and session history. On iPhone, breathing status can also be added to the Apple Health app.
Key features
Built around how people use it
Real-Time Breathing Waveforms
Live waveforms and metrics show breath rate, minute ventilation, tidal volume, and inhalation and exhalation times as the user breathes.
Spirometry and Peak Flow
Users run spirometry tests and measure peak flow, supporting asthma and exercise-induced asthma management from a mobile phone.
Guided Breathing Training
Structured diaphragmatic breathing sessions help users train their breathing muscles and measure breathing effort and efficiency.
Session History and Reports
Session logs and summary breathing reports for meditation and exercise let users track their improvement over time.
Apple Health Integration
Breathing status can be added to the Apple Health app, so users see it alongside their other health metrics.
