Best parental control setup for multiple kids?

We've got 3 kids (6, 8, 11) with various devices and I'm honestly overwhelmed trying to manage everyone's screen time separately. Right now I'm using:

• iPad built-in Screen Time for the youngest
• Android's parental controls (poorly) for the 8yo
• iPhone Screen Time for the 11yo

Is there a single dashboard system that works across everything? Apple's Family Sharing is ok but doesn't cover Android. I'd rather pay for something that consolidates everything instead of checking three different apps every day.
