Adding steps

I have an iphone and was using this to add my steps to mfp , after the next to last upgrade I started having lots of problems with each app failing to recognise the other so I switched to using moves. Now most of the time my iphone steps work and sometimes moves doesn't!!, but which should i use, moves just adds all the calories from exercise which tends to look generous , whilst the iphone makes an adjustment which generally seems to look mean , (either way am bit fed up that upgrades often make an app less effective rather than better!)
