The Kinderopvangtoeslag app is a free Android application developed by Belastingdienst that helps parents manage their childcare allowance. It requires a DigiD for the first login.

With this app, you can view your allowance and childcare details for the entire year and make changes such as updating your childcare hours, hourly rate, adding new childcare for siblings, stopping childcare, or changing your income. However, if you don't have a childcare allowance yet, you can't use this app and need to apply for it through Mijn toeslagen.

The app is a great way to keep track of your childcare allowance and make necessary changes quickly and easily. It's perfect for busy parents who want to manage their finances on the go.
