Pacer is a smartphone-based fitness tracker, meaning that participants are not required to purchase separate, often costly wearable fitness trackers. Participants need only to carry their smartphones with them as they start stepping, as the Pacer app works with a user's smartphone to collect activity measured by the phone's hardware.
In addition, if a participant should forget her phone, Pacer & P4T allows manually added participant data to be considered in the challenge rules, should Admins allow it.
