You understood the explanation until the question changed slightly. Khan Academy is a candidate when you want to move between an explanation and an attempt at the underlying skill.
What the listing establishes
The current publisher listing describes videos, articles, exercises, feedback and downloaded video content. It also says some website functions are not available in the app, naming areas such as teacher tools and programming content. The mobile product is therefore not a complete substitute for every website workflow.
The AppleApps read
Consider it when you can name a topic you want to understand rather than merely collect. A specific skill gives you a useful comparison: can you follow the explanation, attempt a related problem and identify what you still do not understand?
The main app is distinct from Khan Academy Kids. Choosing between them should follow the learner and task, not the shared publisher name.
A useful first check
Find the actual topic and inspect whether the activity you need is present on mobile. Attempt an ordinary practice item after reading or watching the explanation. Treat an incorrect answer as information about what to revisit rather than an instruction to rush through another lesson.
If you need offline use, check a downloaded video separately from an exercise or account-sync feature. The listing’s video-download statement should not be extended to the entire app without further documentation.
Before you commit
Decide whether account synchronisation matters to your study routine and inspect the setup it requires. If your school or course relies on teacher tools, programming work or another web feature, confirm the right platform before assuming your phone can complete it all.
For a continuing learning need, compare the material with your class or teacher’s expectations. A useful app can support practice without replacing personal feedback or establishing that a particular course matches every syllabus.
