Mitoshi Handbook — A free household budget management app (household account book) that shows your end-of-month balance

"How much money do I have left to spend this month?" "How much will today's shopping cost roughly?"—I created this to answer those two questions before you spend.

With the Mitoshi Handbook, when you write down your upcoming plans, the amount remaining at the end of the month appears automatically. You can jot down meal plans and things you want to buy in the "basket," and before shopping you'll see a rough total. At the store, it becomes your shopping list. When you get home, you "confirm" it, and it goes straight into your household budget record.

Since credit card usage dates and payment dates are handled separately, your end-of-month forecast won't diverge from reality. It's an app like a handbook that uses everyday language instead of accounting jargon, and lets you categorize things with sticky notes (colored stickers).
