About this category
Why we build Education apps
Learning apps work best when they make progress legible. A timeline you can move through shows you how much ground you have covered; a mental-math drill shows you a number that improves.
These titles turn two broad subjects — world history and everyday arithmetic — into sessions short enough to actually repeat daily.
