Revenue, expenditure and a financial overview, all without graphical bells and whistles: the Housekeeping Book app for Android smartphones is limited to the bare essentials. Users of the free app can create various accounts and in them fill out their income and outgoings. Where the money goes can be displayed in a variety of different graphs and charts. The app is free and manages without ads or data collecting. There isn't yet a version for iOS or other smartphone operating systems.
