After having tried many different types of brain exercising apps, I decided on Kopfnuss because it is inexpensive at 99 cents and it has plenty of good reviews on its App Store page. Nevertheless, I am very pleased with my decision, because Kopfnuss has improved my quick math solving skills. Anyone can use this app, and it would be extremely useful for those who have trouble doing calculations in their head.

The best features of Kopfnuss are:

- The interface is extremely user-friendly, so I can allow any one of my friends to use the app and I do not have to tell them how it works. They can figure it all out on their own. Everyone I know who has tried the app has seemed to be happy with it. I am especially happy with it because it is so easy to use. I can start using it right away, and it does not take a long time to load. The colors of the text and the background are also visually-appealing, which makes Kopfnuss easier on the eyes.

- Kopfnuss has a few game modes. The user can complete the exercises, which have no time limits. This means that you can just try to train yourself to work on the problems in your head. This is perhaps one of my favorite modes because I can play endlessly without feeling rushed. However, if I want a challenge I will play the 90-second time trial mode. This is my favorite game mode because the app makes the gameplay really challenging. The problems are also great because they make you think. Some of them are very simple, and they are all given at random so you do not know what to expect next. This is all part of training the brain to respond to math problems as fast as it possibly can.

- One of my favorite features is the ability to choose user profiles. So, if you are playing the game with a few other people, you can keep track of your own progress by creating your own profile. The app will also take your user data and compile it so that you can easily see your progress.

Overall, I would highly recommend Kopfnuss. At a mere 99 cents, Kopfnuss is a great bargain. The game is well-made, and it offers plenty of challenging gameplay that almost anyone would enjoy.
