I like idea of alarm clock app that It runs all night with rss and twiter but I'm wonderig how bad is it for iPad screen, battery, etc. Since screen is on all the time can't it damage iPad?
Sorry for my bad english.
I run my alarm app overnight with the brightness turned all the way down and with Auto-Brightness turned off. I've been doing this for several months with no effect on the screen. The one I use is "Beautiful Clock Radio", and although it allows me to touch the screen to brighten or dim the numbers it doesn't otherwise appear to have any features designed to limit burn in.
