Absolutely nothing! Mine counts my steps and nothing else.
If I'm not at my desk, I'm not on Fab.
(suddenly, my evenings here on the nocturnal threads seem much, much more depressing)
Fab
Heart app ( counts daily steps)
OVO ( tells me how much credit I have for energy)
NatWest ( tells me how little money I have)
And my old fav Deezer!
