Stable Version 1.0

3 stars are at first glance certainly not much, but the deductions of 2 stars are available for 1: missing translation German and 2: no access to calendar functions. The latter is more annoying for me. Otherwise, running the app. stable on the FireHD. Access to mail, SkyDrive, account profile and contacts work perfectly.
With the possibility of calendar usage I would even give almost 5 stars.
