Read full description

The AP Visual Memory Trainer — a fun and interactive iOS app designed especially for students of all ages! This app uses a clever trick called Schulte Tables, which are grids that help sharpen your focus, memory, and visual skills. Imagine a 5×5 grid filled with 25 cells, and two exciting games that challenge you in different ways: 1. Visual Memory Challenge (Match Numbers) In this game, you get to train your memory by looking at a grid where some cells show numbers for just a second. Your task is to remember exactly where these numbers are placed. You can choose how many spots you want to test yourself on, making it as easy or as challenging as you like! 2. Sequence Sprint (Schulte Table) You can monitor your activity and progress using History and Statistics tabsHere’s a fast-paced challenge where you must find and tap all 25 numbers in the right order as quickly as possible. It’s like a race against time that helps sharpen your focus and speeds up your thinking. You are able to monitor your activity and progress using History and Statistics tabs. You can use the focus (concentration) marker in the center of the screen to properly develop your peripheral vision. To diversify your user experience with the app, you can choose from several themes for numbers. After each session of the game, the app calculates the percentage of your success and provides additional visual information that you can use for self-checking and improving of your skills.
