At the beginning of the week I mentioned Argus, an iOS 7 app that made use of the iPhone 5S M7 motion processor chip.
After a bit of research, I have found a few other apps.
Strava Run – https://itunes.apple.com/gb/app/strava-run-gps-running-training/id488914018?mt=8
Pedometer++ – https://itunes.apple.com/gb/app/pedometer++/id712286167?mt=8
WeatherRun – https://itunes.apple.com/gb/app/weatherrun-bike-walk-hike/id599397919?mt=8
Argus – https://itunes.apple.com/gb/app/argus-motion-fitness-tracker/id624329444?mt=8
Nike+ Move is soon to be updated to make full use of the M7 processor as will a number of other apps.
This is what makes the iPhone always greater than the sum of its total parts. App support and third party accessories is extensive providing additional uses for the phone.
