Very interesting article by @hamishmckenzie on the subject of using apps (Fjuul and Moves) on our mobile devices to track our movement instead of using Jawbone, Fitbit, Shine or Fuelband.
iPhones app: Fjuul and Moves
< READ HERE >
The best point for both these apps are that the apps are free and anyone can get into the "tracking" game. If you previously wanted to get into the game you had to shell out 100€ to get either the Jawbone, Fitbits, Shine and Fuelband.
However the battery drain on the iPhones will be the Achilles heel... no-one wants a dead phone at any time of the day or night. Even if these apps are lightweight on the battery that anxiety of having a dead battery would be too much for me.
