Financial Goals are made to help you save up money for the future expenses. After you complete the Goal, your money will be transfered into account you choose and will be available to spent.
To add a Goal tap “plus” icon in the the expense category area. Then switch category type to Financial Goal. Name it, set up sum you want to put by and choose a currency of savings. For instance, I want to buy a bike, so you see Goal named “Bike” on the screen below.
