お父さんこづかい帳 is an app developed by SoftBank Corp. that helps you manage your allowance. With this app, you can input your income and expenses on a daily basis and track your financial status through graphs and tables on a monthly basis.

One unique feature of this app is that if you input your income and expenses every day for a month, you will receive reward stamps from the app's character, the father of the Shirato family, on the graph.

The "お父さんユーティリティアプリ" series is a collection of free smartphone applications designed with the Shirato family's father in mind. These apps not only provide useful functions but also have a visually appealing design that adds an element of fun to your daily life.
