Budget Tracker app helps you to create budget projects and track incomes/expenses. Every new project can have a starting and ending date, currency of your choice and initial budget.
All the expenses could be organised by categories, the remaining balance could be displayed visually in several different ways. You can sort your expenses/incomes by date or amount.
At any moment you can convert any project to another currency with historical data available to make a conversion with any date in the past.
