Finance management is always hard because of the complexity of tools. "o.o1" (or "Cent") offers a very simple and intuitive design to be in touch with your current financial status.
You have a possibility to see the current balance (top right corner) and statistics for each month with incomes and outcomes.
The main difference between other similar tools is a view with split by type operations and configurable operations categories.
In the Settings section, you can select your currency format (each currency format has each own specific view).
