Household Budget Board

I have developed and released "Kakeibo Board," a free household budget management web application.

https://kakei-board.com

It is a web-based household budget service that allows you to record expenses and income, manage fixed costs, manage categories, and perform analysis.

It supports both smartphones and PCs, and if you register an account, you can sync data across multiple devices.

Personally, I found existing household budget services unsatisfactory because they:

・Require integration with banks and securities accounts as a prerequisite
・Are based on paid plans
・Have outdated UI
・Are difficult to use on PC or not supported at all

So I was creating and managing my own household budget using spreadsheets. I thought, why not turn this into a web service? I developed it with the goal of achieving equal or better usability than my spreadsheet version.

I put particular thought into the category features to make it easier to understand spending details when reviewing finances later.

For example, for a drinking party, some people might want to classify it under both "Social Expenses" and "Dining Out Expenses," so I designed it to allow multiple categories to be attached to a single expense.

Rather than simply viewing mechanically classified results, it's an application that takes the best of both worlds—allowing you to organize expenses according to your own sense while automating what can be automated, based on traditional household budget management.

Some people might want to quickly register just the title and amount from their smartphone while out, and then categorize and add notes on a PC later to organize everything (that's exactly my type), so I've prepared a quick input screen with a streamlined UI for quickly registering expenses from a smartphone. (It can also be used from a PC.)

There are no paid plans—everything is available for free.

I've written about the development background, design, and implementation details in a blog post, so please take a look!
