About Khan Academy
Khan Academy is a nonprofit education service offering free lessons, practice exercises and videos. The Google Play listing says you can learn anything for free, and its subjects include maths, science and other school topics from early learning through later years.
The app lets you follow courses at your own pace, watch lessons and practise with exercises that give feedback. Content is organised by subject and grade, and downloads let you study when offline. Teachers and parents can use accounts to assign work and track progress.
The app is free, and no in-app purchases are shown on Google Play. It suits students who want extra practice, parents supporting homework, and adult learners who want to refresh basics. Because it is a nonprofit, it does not rely on advertising and does not charge for content. The Google Play rating is lower than the App Store one, but the content itself is well regarded. Use the website if you need the full range of resources.
Create an account so your progress is saved. For classroom use, teachers can set up classes on the website.
