Do it yourself auto tracker?

Hey guys, Is there a product I can buy that keeps track of the service I do on me and my girlfriends cars? I am always looking it up again and again. I feel like there has to be something in an auto parts store or online? thanks in advance people!

I have been using an auto service tracker from oil change brain. I like it, super cheap and makes it easy to keep track of service. See if it is what you are talking about. www.oilchangebrain.com
