Hi, I've found a nice Android App to check on adsense earnings without going to adsense admin in a browser.
The name of the App is AdSense Dashboard, it's free otherwise I wouldn't have talked about it.
Anyway, it's very handy, the first screen shows you earnings and stats from today and yesterday, and then give you earnings and less stats about current month, last month and current year and lifetime earnings.
After you have other screen with more datas, and graphics.
Here's the link of this app on the Android market: https://market.android.com/details?id=com.ctoforaday.asfedash&hl=en
Very handy, hope it helps you if you were looking for such an android app.
If you're using another app for the same thing, could you please give its name here? I'm ok to test several, maybe AdSense Dashboard is not the best.
