I really like ClockPlus. Chances are high that the only time is when I'm charging my phone overnight. Being a light sleeper, its kinda handy to just grab my phone and see if there's anything important I need to know about. It rarely happens, but still.
Plus its nice to have the ability to adjust the brightness/dimness on a slider rather then just having a "night mode" checkbox that may or may not be dim enough for me.
I like clock plus too, but I wish there was a way to make the day dream transparent instead of having an all black screen.
