My Budget Book is a mobile app that helps users manage their finances by easily recording their income and expenses. It offers features such as individual or recurring transactions, allowing users to track and forecast their balances. The app also provides visualizations of records through dynamic charts and graphs, making it easier for users to understand their income and expenses in a new way. Additionally, My Budget Book offers a budget mode where users can set limits or goals over custom periods of time, helping them control their spending and save for specific targets.

One of the key highlights of My Budget Book is its offline functionality, which does not require internet permission to protect users' privacy. The app also does not contain any advertising or hidden in-app costs, with voluntary donations being the only form of payment. Users can personalize the app's Material Design layout, including a configurable dark mode. The app offers comprehensive views with convenient tabs and a wide variety of sorting options, allowing users to easily navigate and organize their financial data. Users can also manage multiple accounts and make transfers between them, customize categories and subcategories, and add photos or receipts to transactions for reference or to reduce paper clutter.

To ensure data security, My Budget Book allows users to protect their sensitive information with a password or fingerprint. The app also provides options for importing existing data or bank statements using the CSV import feature, and users can export their data as HTML, Excel, or CSV files for viewing or printing on a computer. Automatic local backups are available to prevent data loss, and users can create their own backups at any time. The app also offers four widgets for added convenience on the home screen. My Budget Book is continuously being developed and improved, with a comprehensive manual and support available to assist users in making the most of its features.
