Size test vs MindSpan Memory Booster

This app is designed to assess how quickly the user reacts to changes in the size of an object. Users can select one of the test modes: 'Increasing the object', 'Decreasing the object', 'Decreasing or increasing the object'. When the user observes a change in the size of an object, the user must break contact with the device screen. The recorded test time reflects the user's ability to perceive the change in object size. Once the test is completed, the results are tested for normality of distribution (Shapiro-Wilk test). If the values deviate from the law of normal distribution, the program analyzes the data sets, removes the worst value and adds an additional attempt. In the program settings you can select the number of attempts - from 10 to 30. The choice of the number of attempts depends on the performer's age and professional activity. In addition, in the program settings the user can save a backup copy of his measurements in JSON format anywhere (Save backup), add measurements from another device (Add backup), replace already saved measurements with new ones (Replace backup) or delete all data (Delete all data). This application is intended to be used by athletes and teachers in specialized educational institutions for scientific research.

Watch. Remember. Answer. MindSpan trains the most important cognitive skill you have: working memory. A shape moves across the screen. You watch. Then you answer: what was it? What color? What pattern? Sounds simple. It isn't. HOW IT WORKS Each round, a geometric shape — triangle, star, polygon, moon — travels along a path. Your job: hold it in mind, then identify it from a set of options. As you improve, shapes move faster, paths grow more complex, and the distractors look more alike. CHALLENGE LEVELS Between the memory rounds, brain-teasers change the pace — mental math, logic and odd-one-out puzzles, lateral-thinking riddles, and number patterns. The question stays on screen; you reason it through. Memory and reasoning, woven together, so no two sessions feel the same. WHAT YOU'RE TRAINING Working memory is the brain's scratchpad — the ability to hold and manipulate information in real time. It underlies reading comprehension, mental arithmetic, decision-making, and sustained focus. Research consistently links working memory capacity to fluid intelligence and learning ability.
