About this app

Encyclopedic Dictionary is a complete offline reference built around a database of over 66,000 entries. It is installed together with the app — no account, no subscription and no connection required.

One app for looking words up, listening to them, collecting them and learning them.

• Full tablet and landscape support

It works as Encyclopedic Dictionary, as an offline reference without internet, as a vocabulary builder and as a word learning app.

This is an offline dictionary — the database is kept on your device, so it needs some storage space.
