My Vocabulary Lists vs when

My Vocabulary is an ad-free dictionary app with a simple user interface, allowing you to quickly search for words and add them to lists you create. Organize your lists into folders and share them with students, friends or family, or keep your lists private and use them as your own personal English language study guide. The My Vocabulary app was built specifically for students, teachers, autodidacts and logophiles who are looking to improve and expand their English language vocabulary. Our dictionary includes 350,000+ words and phrases from multiple dictionary sources. Each word found in the dictionary features an audio file to hear the proper pronunciation of the word, the syllables for the word, related words, and examples of how the word may be used in a sentence. Related words can be tapped to follow 'word paths'. This will allow you to expand your vocabulary beyond the single word for which you searched. All users can save words from the dictionary into a default vocabulary list and folder and paid members can create new folders and new lists. Teachers can create custom word lists that they can make public and share with all the students in their class. Then, students can save the lists to their favorites and use it as a study guide. Every word search is automatically saved into your Word History so you can refer back quickly. My Vocabulary may be the best way for native, and non-native English speakers alike, to expand their communication prowess.

"四次元年表" is a project where users collaborate to build a database that encompasses all historical events, from the origins of the universe to the endless "now", regardless of the field. It aims to accurately display both temporal and spatial distances by making "where" as important as "when".
