Improve memory skills with these apps

Improve memory skills with the five Apps which helps you to become genius, that is to improve your brain skills while fun with some exercise, keeping that in mind, I put together this collection of apps to help us give our brains a little exercise. Some are for iOS, some are for Android, and some are for both. Also, of course, I recommend these apps or both adult and children

Stack the States (iOS|Android)

There's no better place to start than in our own back yard(s). Stack the States turns learning the state capitols, geographical locations, and flags of our 50 states into a fun game.your job is to pick from four states pictured at the top of the screen. If you select the correct state, you can drop it to the bottom of the screen. On your next correctly answered question, you'll get another to add to your stack. cute graphics add to the fun, making this game enjoyable for both children and adults.

Quick Math+ (iOS)

Want to brush up on your basic math skills? Quick Math+ challenges you to answer math equations correctly in the fastest time possible in order to earn a three star rating. When you figure out the answer, you write the number with your finger right on the screen. There are four different skill levels from beginner to extreme, so this game will be challenging for both kids and adults. When you finish a set of problems, a progress screen shows you how you faired against previous attempts so you know if you're improving. The game comes with four different game variations, but all challenge you to do problems in your head to get the quickest time possible. I really like the challenge of going for the best time because it makes the game about how quickly you can answer questions rather than just getting the correct answer.

WolframAlpha (iOS|Android)

Rather than a game, WolframAlpha is an answer engine that answers factual questions directly, by computing the answer from sourced curated data. In other words, you can ask a complex question like "How old was Thomas Jefferson in 1780?" or "What is the diameter of Saturn?" and WolframAlpha will access thousands of domains to compute and bring you the answer directly, rather than give you a list of documents or Web sites like a search engine.

WikiLinks (iOS)

Most people know Wikipedia and the enormous amount of information you can access just by entering a search term. Most also know how quickly a person can get lost in all that information going from link to link and article to article. What WikiLinks does is it gives you a diagram of each link so you can track how you got from one page to another and read associated articles by touching a point in the diagram. It also organises images associated with your current page at the top of the screen for easy access.

Geomaster (iOS)

Once you've mastered the states in our union by playing Stack the States above, you need to expand your horizons by learning the countries of the world. Geomaster turns learning countries, monuments, flags, and major mountain ranges and bodies of water into a game.To play, you simply pick a region like Europe, Asia, South America, or Africa, then start the game. Geomaster gives you a blank map (with country borders) and then displays the name of a country at the top. You answer by tapping the country on the map, and you can zoom in to the smaller countries with a pinch gesture. The object is to fill in the entire region in as little time as possible.
I'm a little ashamed to say I had a rough time picking out all the Latin American countries in my testing, but it helped me learn them by showing me the correct location with each wrong answer, then randomly bringing the same question back later.
