Khan Academy vs ScratchJr

Khan Academy is a free learning platform for independent learners, teachers and parents, available on Android, iOS and the web. It offers more than 840 free courses in core academic subjects for K–12 and early college, with personalized learning intended to help students master concepts and address learning gaps. The mobile app includes interactive exercises, mastery levels, synced progress, offline video downloads and a scratchpad. Khan Academy Kids is a free, ad-free app for children ages 2–8 with interactive books, games and creative lessons. Khanmigo tutoring guides learners toward answers across academic subjects from elementary school through college. Teacher tools can assist with lesson planning, feedback, student work summaries, rubrics and exit tickets; Khan Academy for Teachers also includes standards-aligned practice, progress tracking and AI support. Teachers can import Google Classroom rosters, while district plans list Clever or ClassLink rostering and single sign-on. Paid Khanmigo subscriptions require users to be at least 18, live in the United States and have a U.S. billing address. Parent and learner subscriptions each cost $4 a month.

ScratchJr is a free introductory programming app for children ages 5–7 to create interactive stories and games. Children snap graphical blocks together to make characters move, jump, dance, and sing. They can edit characters in a paint editor, add voices and sounds, and include photos in projects. The app is designed to support young children's cognitive, personal, social, and emotional growth. ScratchJr is developed for iPads running iOS 10 or later and Android tablets running Android 5 or later; it may also run with limitations on some Chromebooks, Apple-silicon MacBooks, Fire tablets, and Windows 11 PCs. Devices that run it in a virtual container may have limits on importing and exporting projects. Projects, including their images and recordings, are stored on the device and are not sent to or accessible by Scratch. The privacy policy says the app collects use preferences and automatically gathers country-level IP and device information; it may also collect usage information such as time spent in the app. Projects can be shared by email, or by AirDrop on iPads. The site offers teacher-led activities and ScratchJr Connect, a free resource database.
