Many people think it's easier to get up from the bed in the morning if they are wakened by light instead of sound. This app works as a wake-up light: you can set a time, and at that time a simulated sunrise will start. For about 30 minutes the screen will slowly become brighter and brighter. Hopefully this will eventually wake you up. If it does not, after 40 minutes the screen will start to flash.
If light alone is not enough to wake you up, you can also add a sound. Either some simple piano playing, or a nature sound with beautiful birds.
Place your phone close to your bed. You should see its screen shining up into the ceiling, but not look directly at the screen. This app uses a 24-hour clock only.
(After about 60 minutes with no interaction from you, the sunrise will just end. This is a security feature to make sure it doesn't stay on forever, in case you forget about the alarm. If sound is on, a classic wake-up alarm will be played first.)
EVEN THOUGH THIS APP IS DESIGNED TO WAKE YOU UP, THERE IS NO GUARANTEE THAT IT WILL WORK. YOU MAY SLEEP TOO DEEP, THERE MAY BE UNKNOWN BUGS, OR YOUR PHONE MAY RUN OUT OF BATTERY POWER. IF IT IS VERY IMPORTANT TO GET UP BEFORE A SPECIFIED TIME, ALWAYS USE A REGULAR ALARM CLOCK AS BACKUP. USE THIS APP ON YOUR OWN RISK.
