YouTube Kids might be a bit more popular than Sanako. We know about 1 link to it since March 2021 and only 1 link to Sanako. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Haven't tried them personally, but had run across https://sanako.com/ and https://withprimer.com/. Looks like primer is more for home-schooling though. Source: about 3 years ago
Also there is featured YouTube Kids content like PragerU Kids and the upcoming DailyWire Kids. I'm sure that just like PragerU Kids, when DailyWire Kids launches it will be featured content on the YouTube Kids app. Gotta start the right wing indoctrination at the earliest age possible via kid friendly platforms like the YouTube Kids app. Source: about 2 years ago
