I have found the Json url for the main page but is there other json for user stats ?
I'm making a Iphone app (don't know if apple will aprove it).

Nobody know where i can find API information ?

if you make an app that just read JSON data on a web server and display them on screen, I do not see reasons why Apple should approve...

That's how 80% or more of the Coin Mining Monitoring apps in the Apple App Store and Android Play store work. Wink

The differentiator is how much eye candy and extra features (BTC Calculators and such) they wrap around this base feature.
