Recently I came across this beautiful app, while searching for good email app for corporate account. This app not only helps you in managing your emails, but also divides your work life from normal life, which can be accessed like switching between launchers.
From Play Store: Divide delivers the ultimate mobile productivity tool to get work done securely on your Android device. Check your work email, view your calendar, look up contacts and more, all in one encrypted workspace without worrying about your privacy or the threat of your company wiping your device. Divide syncs with Exchange ActiveSync, Google Apps, and Lotus Notes and offers a complete BYOD solution for individuals and IT.
