Any way to get detailed data usage on an iPhone?

[Red Storm]

I want to see what apps are using how much data on our iPhones, but I don't know how? Ideally I could see both wifi and mobile data, but the more important one is mobile data. Stats from my carrier account page aren't the answer, that just shows total data used.

Settings -> General -> Usage
-gives you battery usage, local storage used, icloud storage used

Settings -> Cellular
-gives you call time, cellular data usage, and breakdown of app cellular data usage

I don't think there's anything that tells you the app wifi data usage.

This is what I'm looking for. I don't see an option to specify a time period though, so I assume the numbers shown are since the app was installed?

That's correct (unless you hit the 'Reset Statistics' at the bottom )

as for specifying a timeframe, you'll need a separate monitoring app for that, like this:

(though i can't say how well they work as i haven't tried myself.)
