Caterpillar, a for-pay app which includes 6 mini apps (which look surprisingly like apps which have already been released), allows you to tweak tons of settings and such on your iPhone, from events on your lock screen to new system fonts to a smart dialer. Brought to you by Unsanity, the same guys who make ShapeShifter for OS X.
