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.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.

word-vaultWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
