From Neuroapp we hope you want to foster your concentration becasuse the app recommended for this week requires a lot of observational skills.
90 numbers is a simple app to train attention (selective and sustained) and also to develop observational skills (for example, visual tracking). Task consist of tapping numbers in order (1-10, 1-20), depends on the level of difficulty which is unlocked according to user execution. The higher level you are the more numbers you has to find. At the end user get a number of stars considering time required to complete task (3-excellent observation, 2-very good observation, 1-satisfactory observation), in this way we can train also proccesing speed.
Free app available on Apple Store and Google Play:
