Building a Cardio Tracking App for Android
Lewis Gavin

Awesome breakdown of the individual components you had working on the app. Sensors are always a little weird to me but your explanation was clear and concise!

Can sensors run in the background while your phone is locked? Having the ability to lock your phone while the app tracks your steps would be great. Be sure to share if you ever open source it, I think a lot of people would like to health apps that aren’t behind paywalls.
