We recommend that separated parents pay their half of the allowance on the same say, either each week or each month. This way, it is easier for children to learn managing money since their allowance is recurring and that it is consistent.
Please note that our bonus system works so that everyone sets the bonus they consider appropriate for the child. For example, in order to achieve a 1% bonus, two people who transfer an allowance should set a 0.5% bonus. You can do this in the allowance settings. The idea behind this approach is to make it easier for parents who want to give different bonuses.
