What to know
A research study paying per day of wearable data on top of a $20 enrolment payment and a device it lends; a participation reward rather than a data sale, so a floor for what a day of wearable data is worth to a researcher.
Arithmetic
Stated by the source as $1 per qualifying day (up to $35 per month with the random $5 days).
