EcoSurvivor is a personal finance manager that treats your budget like the supplies in a bunker: income and expenses become *reserves*, category budgets become *rations*, and a *survival index* tells you with a single number how long you'd last at your current pace. Under the narrative skin, the job is the same as it has always been: write down where your money goes until you actually start to see it. It's not a new idea — it's over a century old. ## The ancestor: Japanese kakebo In **1904**, **Hani Motoko** — the first woman to work as a journalist in Japan — published a household accounting method designed for the families of her country: the **kakebo** (家計種, *kakeibo*), literally the «household ledger». It wasn't a technical invention: it was a discipline. A notebook, a pen, half an hour at the start of the month to set your income and a savings goal, and a daily record of every expense, split into four categories — needs (food, home, transport), culture and personal growth, leisure and extras, and the unexpected. At the end of the month, a written reflection: what went well, what to change. The principle behind kakebo is almost philosophical before it's financial: **writing by hand slows you down, and slowing down forces you to look**. It isn't the math of saving that does the work on its own — it's the awareness that comes from putting it down in writing, with your own hands, where every yen you spend goes. More than a century later, the method is still taught and practiced, even outside Japan, precisely because that discipline of attention has never gone out of style. Field note EcoSurvivor isn't a digitized kakebo in the strict sense — it doesn't force you to write by hand, and its calculations are automatic and instant, not monthly. But it inherits the same underlying principle: make the flow of money visible, category by category, so you're forced to look at it. Where kakebo uses the slowness of paper, EcoSurvivor uses the gamification of the bunker — an index that rises or falls in real time, instead of a written reflection at the end of the month. ## How it works - **RESERVES** — your total balance, updated with every entry you log, with a chart of the last twelve months - **RATIONS** — monthly budgets by category (food, shelter, transport, fuel, medical…), with a bar that warns you when you go over — the most direct legacy of kakebo's four categories - **SURVIVAL INDEX** — a number from 0 to 100 calculated from your savings rate and how well you stick to your rations - **FIELD MANUAL** — ten chapters of financial education, to read whenever you have a spare minute - **LOG** — every transaction, filterable, deletable with a long press - **OFFLINE BY DESIGN** — no account, no cloud, no ads: your data stays on your phone; the Internet is only used to check the licence ![EcoSurvivor's Ration Plan screen: total monthly budget card and the list of rations by category with progress bars](https://survival-apps.com/assets/img/ecosurvivor-razioni.webp) The rations: a spending cap for each category — the same logic as kakebo's four categories. ## See it in action A real recording of the app, with sample data.
