kontonom

kontonom's Budget Book helps you stay on top of your money — no account, no cloud, no ads. Set a monthly budget per category, record what you spend, and see at a glance how much is left. Whatever you do not spend rolls over into the next month (the envelope principle), and so does an overspend — which keeps the arithmetic honest across months instead of resetting every four weeks. • Budgets per category with planned vs. actual and the remaining amount • Roll-over into the following month, calculated to the cent • Fixed costs handled properly: rent paid on the first of the month does not mean you are spending too fast • Pace indicator: are you on plan for this point in the month? • All your data stays on your device This is kontonom for Android — the same home banking application also available on desktop. This first release covers the Budget Book; bank connectivity and sync follow.
