A lot or a little?
Parents need to know that Knowin: Learn Coding is a free app that provides kids with basic coding knowledge and instruction. The free version is ad-supported, but families can upgrade to an ad-free version with more content and offline access for $2.99/month or $9.99/year. The upgrade is an in-app purchase requiring no parental permission. This experience requires no typing (kids tap on correct answers). For that reason, the free version might be just right for kids to start out before moving onto tools that let them actually type in code. There are external links to other resources in each of the lesson areas. Read the developer's privacy policy for details on how your (or your kids') information is collected, used, and shared and any choices you may have in the matter, and note that privacy policies and terms of service frequently change.
