Great app, super simple, no settings and great fun to tap for color combination changes. Only thing I wish is that it worked with widgets on your drop down screen and had the colors too. I keep my phone on a 24 hour clock but like to see a 12 hour clock too. Having it on a widget was great until this new iPhone update, now the background is white and the widget is white so you cant see the time!
