Brainify
Read full descriptionHide full description
Brainify was designed to take care of your brain across four categories: speech training, visual focus, memory and maths. • Speech training lets you listen to numbers and simple words, and then listens to your speech so that it can tell you if you speak correctly; • Visual focus games force you to focus and tap on disappearing dots, find missing letters, pick numbers in order and more; • Memory games require you to remember things to complete the games; • Maths games require you to use your brain to compute mathematical computations. Most of the games keep track of your performance and allow your name to appear on the Leaderboard. Challenge your friends and see who is the best! More games that will be child friendly are coming soon. If you have feedback on how we can improve our games for children or if there are any games you would like to suggest for implementation specifically for children, we'd love to hear from you! Some of the games were tested and improved with the help of medical professionals. If you represent a medical institution or an organization looking to work with Brainify, please get in touch. We hope you enjoy the game. If you have any suggestions or issues, please write to us at contact@codingfy.com. Some of the icons inside the app are made by Freepik from www.flaticon.com.
