I've made something to track spending on a weekly basis. I've found that most budget apps are too heavy, and most run on a monthly cycle. I can easily calculate rough figures for fixed income and expenses, I just need something to track spending money. Doing a budget by week is much easier to track and plan, and makes it easier to answer the question "Can I afford this?". Anyway, here is the Android app: https://play.google.com/store/apps/details?id=com.andrewoven...
