I found the absolute best budget app a few months ago and I bet it will work great for your friend. I have tried many different apps for Windows and Android looking for something as close to Quicken as I could find, but one that was either free or really inexpensive. One of the most important features to me, in addition to categories and repeating payments (like rent, utilities, and food, that are the same every month), was being able to quickly see how much money I had left over each month after my monthly bills had been paid, as well as how much I have extra after several months if I stick to my budget. This app easily shows you how much you save each month, in addition to how much you've saved total so far, right on the main page, which is awesome. It also lets you plan your budget, versus requiring you to enter the bills as you pay them, and lets you add categories as well. None of the other apps I tried for Windows or Android offered all of these features. It's called My Budget Book and you can find it in the Play Store. It is $2.99, but well worth it. Quicken is the only other app that I would recommend but it's more expensive and is only on Windows. It's nice to have this one so you can work on your budget on the go and add payments or deposits easily, as you make them, using a widget. I hope this helps and works well for your friends needs!
