The tide of wearable devices is nowhere near its crest, but apps aren’t waiting around for hardware to catch up. Many mobile fitness mavens have already put the iPhone 5S’s M7 motion coprocessor to good use. For more casual use, Nike+ Move provides an excellent snapshot of your daily habits. The app counts “NikeFuel,” Nike’s own sort of fitness currency, rather than calories or steps, which makes it the perfect gateway app into fitness tech. More serious athletes should check out Strava Run, Nike+ Running, Argus, MyTracks by Google and RunKeeper to take it to the next level, no buggy wearable accessory required.
