4grosze - Home Budget
The app offers a "zero-sum" budget that is precise to the penny and a drag-and-drop interface that allows users to move their account to an envelope to record their expenses. It also allows for the joint management of budgets, supports multiple budgets (e.g., home and business), and offers instant synchronization between devices and users. Other features include a receipt mode (multiple items in one entry), the ability to record refunds, and reports and summaries.
It is important to note that the app requires users to create an account and that a demo mode is also available. The mobile app is ideal for recording expenses on the go, while the web version is particularly useful for planning and analysis.
