Word Pyramid目前只有托福词汇的词库。 在这里，50个单词组成了一个list，每背完一遍list，会得到相应的贝壳和经验。贝壳可以帮你建立繁荣的Pyramid！注意：奖励贝壳的数量和你背这个list的遍数有关。第一遍比第二遍得到的贝壳多，第二遍比第三遍得到的贝壳多，这样设置的目的是鼓励大家复习背过的单词！从我自身的经验来看，背了单词不去复习等于没有背。 希望这个APP能够在你背单词的道路上给你帮助。如果在使用的过程中遇到了任何问题，或者你有什么好的建议，请联系：wordpyramid@163.com Have a good time!

Verdict
The clearest difference is price: Word Pyramid at Free against MistakeBook's $1.99. Word Pyramid also leads on iOS requirement (11.0 vs 13.0). MistakeBook's advantage is chart position (#197 vs unranked). On in-app purchases and device support there is nothing between them.
