## What is HRO2?

Allow people to monitor your heart rate and blood oxygen levels remotely using this app. 
Whoever you want to see your data can download this app, they then can tell you their @sign and you can share either or both values with them in near real-time with that @sign.
All data is end to end encrypted so only you and who you shared the data with can see your heart rate or blood oxygen saturation.
