How do I filter expenses by category or tag?

To filter by category or tag, go to the ‘Expenses’ screen (accessible from the middle button in the yellow navigation) and from the filter bar (below the yellow navigation) press the leftmost button with a filter icon. You will be taken to the filter screen, which will slide over from the right. From this screen – to select a category or tag to filter the expenses list by – simply tap on it. Once tapped this will take you back to the expenses list with your filter applied; also, the total amount that you have spent by each filter you apply will be displayed. To display all expenses again, press the filter icon again (the leftmost button located in the filter bar), from the ‘Filter’ screen tap the top most option labeled: ‘Show me everything’
