Hi! My name is James Rogers. I’m a university professor with over 10 years teaching experience, and have used my PhD research and discoveries made by my over 30 member research team to provide learners with resources to help make language learning more efficient. I hope that you find them useful on your journey learning a foreign language. This flashcard app will help Japanese learners master general English. It teaches the most common collocations of English in the form of phrases. Included are over 3,000 phrases taken from the app English Master 10,000, each with an example sentence, with each phrase and sentence translated into Japanese. A 13 member research team took over 3 years to create these contents. Only items which half or more of the phrase are said in a different way than the English were selected. Thus, students can concentrate on only items which are difficult to learn. Audio for all the contents is included as well. Also included is a custom quiz function which you can use and send your results to your teacher with via email. This app also automatically sends all items you miss often to a special “difficult cards” folder to make it easy for you to concentrate on them. What’s more is it features one of the most advanced Leitner algorithms on the market to help you learn more efficiently: you mark items you don’t know wrong and they come back more often, giving you the necessary exposure to master them. Items you mark correct don’t come back as often, so you don’t have to waste your time with items you already know. This method is proven by linguistics research to be the most ideal way to learn. We hope our app helps you improve your English!

Verdict
The clearest difference is in-app purchases: Dual N Back at none against 英語マスター3千's 1. 英語マスター3千's advantage is device support (3 vs 1) and iOS requirement (8.0 vs 17.0). On price and ads there is nothing between them.
