We didn’t ship a hundred features. We shipped the five that actually matter — and we sweat them. Here’s what each one really does.
Rules are the single feature that makes Biankbook different. You log a transaction; Otto notices it's a repeat; one tap teaches him the rule. From then on it lands in the right category and pocket on its own. Rules learn cadence — weekly, biweekly, monthly, irregular — and they pause cleanly when you stop a subscription.
Biankbook tracks four kinds of money: checking, savings, credit, and cash on hand. Add as many of each as you want. We never connect to your bank — you enter the balance, we keep the running total, and transfers between your own accounts don’t get counted as spending or income.
Set a monthly target on any of twelve categories. The bar fills with the category's color; if you cross it, it turns coral. No alerts, no shame. Pair it with the In/Out bar chart — five months of income and spend, side by side — and you'll see the rhythm of your life in about three months.
Pick a name, a target, a deadline. Tell Otto how much you'll add each month. He does the on-track math: how many months it takes at current pace, whether you'll hit your deadline, what the gap is. The Forecast view projects six months forward across all your goals at once.
On the last day of every month, you close the chapter together. The book is sealed; we summarize what you saved, where it went, and what Otto noticed. You level up if you logged consistently — ten named levels, each a kind of attention. Apprentice, Bookkeeper, Steward, Patient Reader.
