There are many, many apps that can help you budget. I am pretty old school and I do it in excel. What you need to do is map out everything you spend your money on first, so you can see if you have any opportunities (i.e. you eat out at restaurants 5 times per week, maybe try cooking one of those days). The main thing about starting to save, is that you don't need to save outside of your comfort zone. Whatever you feel you can comfortably save each week do that, but stay consistent and don't withdraw the money. Even if it's a dollar a week, it will get you in the habit of saving. After a while, it will become easier and easier to save.
