The WeCroak app, which sends reminders that you're going to die -- five times a day, is not meant to be morbid, founder Hansa Bergwall said, but to make us stop and appreciate the moment we're living in. "Remembering that you're going to die is really important," said Bergwall, a publicist, writer and meditation teacher in Brooklyn, who was 11 years old when his mother died. "Sometimes that's all it takes to take a deep breath, change the program and do something different, feel something different."
