There are three ways to send money to your kids:
Send a one-time money transfer, for which you can click on ‘Send money’ from the 'Home' or ‘Wallet’ screen.
Set up a weekly allowance by going to the Earn screen and clicking on ‘Set Allowance.'
Set up a one-time or recurring task by going to the Earn screen and clicking on 'Add a Task'.
Note: Please take a look at the load limits here, to check the amount and number of times you can send money.
