Description

*** Featured on the iTunes Home Page, and in Reference and Education ***

Have you ever looked up a word, only to forget its meaning later?

Word Vault stores all the words you want to remember and helps you to internalize them. Mundane, exotic, functional, highfalutin: amass a cache of words you love, then learn them all.

We learn fastest with frequent exposure to new words. Use Word Vault as your regular dictionary app, and it will remind you to come back and review the words you've looked up. Reviews are quick, fun, and help you to get words out of your phone and into your brain.

Features:
- Robust offline English dictionary, and online lookup for esoteric words
- Vocabulary review system with a configurable schedule
- Pronunciations
- Images and Illustrations
- Translations (See note* below!)
- Auto-complete and spell-check suggestions
- Thesaurus functionality
- Customization of your word list with notes, sources, and favorites
- Example sentences
- URL support, so you can look up words from other apps:
wordvault://define?text=yourtext

Psst, Educators: You can purchase Word Vault for students, teachers and administrators at a discount through Apple’s Volume Licensing Program!

*Translation functionality can be activated with a one-time in-app-purchase. Please note that translations are provided for the words looked up and not for definitions. Translations are provided via Microsoft Translator, which does not have a 100% accuracy rate, especially for isolated words without context. An upcoming update will include the ability to test translations in your language of choice before paying for the in-app-purchase, to help you better gauge the value of the functionality before paying.
