The best thing about iOS 8 isn't continuity texting or a liberated keyboard -- it's that it'll give you rock hard abs. Which is exactly what you need if you're going to pull off any of Under Armour's skin-tight clothing. The sports brand wants to help you along with that, and has just updated its suite of apps (the popular MapMy... franchise it bought) to include unified activity tracking. This means if you have compatible hardware (like Jawbone's UP, or a Withings Pulse) or an iPhone with an M7/M8 chip in it, you can fold all your activity data into the one MapMyFitness app. This also means you won't get dupes any more if you were already tracking with the app and a tracker separately. Already working on those biceps by lifting your fancy new iPhone 6 Plus? Good, because the apps have also been given a digital nip and tuck to look extra buff on the new larger displays.
