Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
one plus one automation
This app helps children automate addition and subtraction skills. It uses intelligent training methods based on memory principles to reinforce learned tasks and improve recall speed. Designed for children who already understand basic math concepts, it focuses on memorization for more complex calculations.
- Addition and subtraction up to 20
- Intelligent training based on memory
- Individual learning progress tracking
- Written and spoken task presentation
- Distraction-free learning environment
- Timed challenges for recall speed

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).

Mit dieser App kann die elementare Variante des klassischen Nim-Spiels auf herausfordernde Weise erkundet werden. Neben verschiedenen Einstellungen und dem Spiel ermöglicht ein Archiv der Spiele, sich intensive Gedanken zur Gewinnstrategie zu machen. Dabei können verschiedene Parameter angepasst werden, so dass die App nicht nur für Grundschulkinder spannend ist, sondern auch Erwachsene vor spannende Herausforderungen stellt. Die App wurde von Prof. Günter Krauthausen (Universität Hamburg) und Dr. Heiko Etzold (Universität Potsdam) entwickelt und dient als digitale Experimentierumgebungen zur Strategiefindung für den Grundschulunterricht Mathematik. Eine Handreichung für den Einsatz im Schulunterricht mit vielfältigen Hintergrundinformationen zum Nim-Spiel und zur App ist über http://heiko-etzold.github.io/nim-material/ zu finden.

Verdict
The clearest difference is price: Nim at Free against one plus one automation's $0.99. one plus one automation's advantage is update cadence (every 2 weeks vs every 6 months) and iOS requirement (9.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
