Word Collector is a simple app that allows you to make your own collection of word.
Whether you are learning a new language or you might visit a foreign country or even studying something new, Word Collector can make it very easy to take notes on terms that you encounter on your path.
You can set the definitions on your own, or you can use the Look Up option that opens Google Translate inside the app, making it trivial for you to quickly find translation and definitions. You can organize your words in different categories, and it also has a search option, that allows you to quickly search for any word, or words, that you have saved.
