Why is it designated as io..?

"The mobile application runs in the background of the phone collecting passive (phone sensor)"data......?? then (patient-reported outcomes) data. Sensor is on all the time?

"Simple set-up allows for secure data collection, clean data transfer, and fast analysis."

Appears to be, build a file of data in RAM, save then transfer....then post analysis of the files with a google app.

IMO, It's not a real time issue....or an IO issue of an operating system for storage memory.

io needs further elaboration, as it's not defined in that passage.
