one plus one automation

A effective, intelligent app to train automatization of addition und subtraction tasks as a basis for further calculating. Some features of the training tool: * addition and subtraction up to 5, 10 or 20 * intelligent training based on how memory works * individual learning progress bar with user profiles (every task has to bee four times right solved) * written and spoken presentation of the tasks * distraction free learning (no adds, popups, in-app-purchases, ...) Before using this app the child should have understood what additon and subtraction means and how to solve tasks. The app does not function as a tool for understanding, only as a tool for automatization of previos understood tasks. The goal of this app is automatization / memorization of the basic addition and subtraction tasks. Automated math basic tasks are important to be able to solve more complex math tasks (e.g. written addition or subtraction) easier, because basic tasks can be retrieved from memory. The training is optimized for your brain. In an intelligent way tasks which are not safely learned will be trained more often and in an shorter time intervals to support momorization of these tasks. Learned tasks will be repeated in higher time intervals so that they will be saved in your long term memory. If you solved all tasks three times in sequence correcly, the last challenge will be to compute against time to test if the solutions can be retrieved fast from memory (and not by couning up).
