Description by Thomas Richardson Written by the developer, not by AppBrain. Click to read.
100 Things You Should Know turns general knowledge into something you can see, test and complete.
Each subject is a finite set of exactly 100 essential ideas. Start with World included, then unlock Science, History, Money, Language, Music and Technology as one-time packs.
Every pack gives you:
• A 100-item knowledge map that fills as you learn
• A quick self-assessment to find what you already know
• Clear explanations, examples and memory hooks
• Learn mode for focused practice
• Quickfire, True or False, What Am I? and Knockout challenges
• Mastery tracking that highlights weak areas and what to revisit next
The goal is not to read another textbook. It is to find out what you know, discover what you do not, and watch the gaps disappear.
World is included with the app. Additional subject packs are optional one-time in-app purchases. There are no subscriptions.
