You can use Simple Alarm to wake up in the morning or to setup reminders for your tasks during the day.

Our alarm app has been cleverly designed to force you out of your sleep by giving you various missions. For photo mode, you set it up by registering a photo of an area or room in your house. Then once the alarm is set, the ONLY way to make it stop ringing is wake up from your sleep and go take a photo of the registered area. Also includes math problem mode where you have to solve math problems for the alarm clock to turn off. For "shake mode," you have to shake a preset(from 30 to 999) amount of times for the alarm clock to turn off. Users are truly enjoying this alarm app and many have devised their own unique methods around the alarm app's requirements. For instance, you could register the foot of the bed as your location, then you would only need to wake up enough to take a picture of the foot of your bed and then go right back to sleep. Of course, this totally circumvents the whole purpose of the app but has become a fun pastime for many users. Works Better Than Other Alarm Clocks Other creative locations that users have come up with include the ceiling of their room, a nightstand, or the floor.
