Khan Academy – Free Learning App for Android

What is Khan Academy?

Khan Academy is a nonprofit educational platform that offers a vast library of instructional videos, interactive exercises and articles. The Android app brings that content to your mobile device, letting you study at your own pace without any cost.

Main features

• Broad subject coverage – Mathematics, science, economics, history, art and more.
• Video lessons – Short, clear explanations created by educators.
• Interactive practice – Exercises with instant feedback and step‑by‑step hints.
• Progress tracking – A mastery system that suggests the next skill to work on.
• Offline access – Bookmark and download videos for study without an internet connection.

How it works

After installing the app, you can browse topics or search for a specific concept. Selecting a lesson opens a video followed by related practice problems. The app records your answers and shows where you need more review. If you create a free Khan Academy account, your progress syncs across devices, so you can start on a phone and continue on a tablet later.

Practical uses

1. Supplement classroom learning – Reinforce concepts taught at school with additional practice.
2. Self‑paced study – Work through entire courses, from basic arithmetic to calculus, on your own schedule.
3. Exam preparation – Use quizzes and test‑style exercises to review before a test.
4. Homeschool support – Access a structured curriculum without purchasing textbooks.
