Does Bark work if I have an iPhone and my child has an Android (or vice versa)?

Yes, Bark works when you have an iPhone and your child has an Android device (or vice versa). Managing a Bark account as a parent is independent of the monitoring we do for the child’s connected accounts. Parents can use the Bark Parent Android app or the Bark website to manage their account.
To monitor a child’s Android device, use the Bark for Kids Android app. To monitor a child’s iOS device, download and install Bark’s Desktop app. No additional app is needed or installed on the child’s iOS device.
