The King of Math app teaches you basic math by offering different math challenges for you to solve. The app has a very simple design and an uninspiring interface, but it does offer free math challenges for learners. The biggest problem is that the app is loaded with adverts that you cannot skip or avoid. Being able to track how many math challenges you have completed makes the learning app feel more like a game.
A free app with in-app purchases
If the King of Math app simply offered its short math lessons and math challenges, then it would be an above-average app and maybe worth downloading. However, the app is littered with adverts that you are forced to watch, and it has pointless in-app purchases that add no value to your user experience. The worst thing is that the in-app purchases are subscriptions that you are charged for on a monthly basis. As you complete math challenges, your profile levels up until you are deemed to be the math king.
Math learners and children may get more out of this app
Some have described the game as addictive, but most people use the app as a learning tool. Some people enjoy leveling up their profile as they complete challenges. If you are learning math or you want a few math challenges, then King of Math may be the app for you. Otherwise, you may be able to find better math teaching apps that are not so money grubbing.
