We have Yoto for our kids and I was initially skeptical (the cards are quite expensive) but actually it's been amazing. Probably the biggest benefit that we didn't even know is that they have a sort of radio/podcast thing for kids called Yoto Daily that's really well produced and totally free.

Mmh, I know the yoto play (https://eu.yotoplay.com/) but are you referencing to a specific open source project?

Yeah that's what I was referring to. In relation to the tonies. It would be a competitor to the tonie box. Both are popular in Ireland.

I did see some stuff about people reverse engineering the tonies back when we first got it, not sure if there's anything similar for yoto.
