1. Click on the "Expense" button under "Available" card.
2. Choose the account that you spent money from.
3. Choose an expense category.
Every time you choose an account or an expense category, the section with accounts or expenses
will "collapse", leaving more space for input of other data - the sums, dates, comment and tags.
To return to the info entered above, slightly pull the screen down. You'll be able to choose accounts and categories again. The same way, you can edit or review the entered info.
