Best education app

Khan Academy is a portal to a higher educational dimension, and is the place to go if you're interested in learning pretty much anything science-, math- or physics-related. The app is still pretty fresh-faced – although Khan Academy itself has been going strong for almost 10 years – but it puts more than 10,000 videos at your fingertips, covering all learning levels in an admirably approachable way.

There are also courses on art history, economics and more. It's all completely free, so we highly recommend you give it a go.
