Are there any good kid friendly apps besides ChessKid

So I’m an idiot. And I didn’t expect the obvious draw back to ChessKid which is that only the first like 5 lessons are free and then you need a subscription. It’s a chess. Com app so it’s my own fault for not seeing this coming. But now I have a usually apathetic 7 year old addicted to chess and absolutely no money to pay for a subscription. Any other fun apps or sites for kids? She can still play some of the bots for free but the lessons were actually really good practice so that’s mainly what I’m looking for.
