How do you keep track of savings?

Hello! I'm a college student who is trying to keep track of what I'm saving for. I only have one savings/checking account. I'm pretty good at saving but I am ridiculously scatterbrained. I forget what I am saving for or how much I have in each category (school tuition, gas, fun, etc.). I've heard there are some online banks that let you have several accounts/categories. What are your ways of keeping track of such things? I'd be really happy if there were a website out there that would help me out since I'm constantly online for classes, e-mail, paying bills... It's just much more convenient for me. I also don't have a lot of money to spend on computer programs (I have a Macbook). I'm sorry if this is a repeat question. I looked through the memories and did not find what I was looking for. Thanks!!
