reply to developer: whatsapp continues to run in background and show notifications even after being closed. why are you unable to do that? .. original comment: I paid $4 for the reminders. However, reminders work only when the application is active. If you exit / shut-down the application, no reminders for you. Developer should design the application in such a way that it continues to run in background even when user exits it. I would like to have my money back unless this problem is rectified.
