This app trains your ability to estimate and gauge pile sizes. Rendered as simple bars, a deck cut into various piles is represented. By gauging the relative sizes of the bars, and with the total number they represent in mind, the user can estimate the individual pile sizes. By cycling into the next phase the app then displays the correct numbers before starting all over again with a new random situation. Does this really train your estimation skills? It certainly increases your aguility in gauging relative pile sizes, processing the numbers, and it gets you into the habit. The idea is to have you much better prepared when facing the same challenge in real. - Note: This app has the minimum design required to achieve its purpose intentionally applying a "less-is-more" approach. 'Gauge Trainer' was created with passion and driven by commitment but if this is not what you expected, and considering the solid price, please do not hesitate to make use of Appstore's return option or contact me directly.
