If I'm in a rush I sometimes use Kiss My Face shave cream without a brush (very rarely). It works better than any shave oil or canned stuff I ever tried, one pump from the dispenser into wet hands a quick rub together to generate the lather and then smeared round a wet face. It's not strictly brush less, it works very well with a brush too. My wife uses it to shave in the shower too. I recently picked up two of the lime ones from Amazon.
