Name your Retirement goal "Old Age". Add your child's name to your various Children's goals (no one has just one!). Call your Wealth goal "Treasure Chest". Get creative :)
Here is how you can do that
Home page → Mutual Funds (either from the center of the screen or from the bottom tab) --> Goal you want to rename --> More option (three lines on the bottom right) --> Edit Goal Name.
Note: If you have not invested in Stocks & ETFs, then you will be on the Mutual Funds page by default.
