My phone displays: "Notification has been set" at each boot I am in doubt. My Galaxy SII phone began recently to display a standard pop-up notification box with the text "Notification has been set" at each boot. I uninstalled the software that I suspected was displaying this popup, there were no notifications in notification area left, but this popup has kept appearing on the screen.

How to track which software is displaying this popup?

Android 4.0.4
Found it. I messed around with adb logcat, adb shell dumpsys and Titanium Backup's Freeze feature. I have succesfully narrowed it down (on my device) to an App called "Pullups 2.04" by "NorthPark" from the Play Store.
