The Problem

There are plenty of fitness devices and apps on the market that track steps and distance but there aren't any that can identify and track the exact type of exercise you're doing and the number of reps; enter Actofit.

Actofit approached our HCDE 517 "Usability Studies" class and asked us to evaluate and test their fitness wristband and companion mobile app to improve the user experience as much as possible before product launch (March 2017). Our three-member team was comprised of fitness enthusiasts who had extensive experience with wearables so we were thrilled for an opportunity to work on this project.
