Xiaomi's popular Mi Band fitness trackers offer extraordinary bang-for-buck but have been let down by a sub-par app experience that felt rough around the edges. This could change today, as the v4.0 update to Mi Fit brings a brand new UI.
Because there clearly weren't enough apps that help you count your steps and/or compare them with your friends, HTC has filled the imperceptible void. Fun Fit is a social fitness app where you and your participating Facebook friends (there are sure to be many!) pick "cute avatars" and compete in the time-honored contest of taking the most steps.
Despite their recent partnership with Under Armour, this would not seem to be a product of it. Rather than UA's more-serious-than-necessary aesthetic, Fun Fit tends toward the overly cheesy. As a product of HTC Research, it probably won't be part of the standard pre-loaded apps on future HTC phones, like the M9.
