What mobile apps do you let your kids use?

We let our kids use educational apps like ABCmouse, Khan Academy Kids, and Duolingo ABC, but limit their screen time to 30 mins per day max. Also have parental controls set up to block inappropriate content or in-app purchases. It's a balance between being protective but also letting them learn tech skills for the modern world IMO.

I let my kids pay Nulls Brawl. They download it from nullsbrawlapkk.com

I prefer limited screen time for mobile use, and for the mobile applications I suggest learning application while watching video

My kids have a curated list of age-appropriate apps.
