Lantern is in beta on iPhone. Android follows the iOS release.

Join the beta

The beta is by invitation for now. Email hello@lanternlanguage.com and we'll send you a TestFlight link.

Everything in the beta is free, including the Study Pro features. We only ask that you tell us what feels wrong — a missing word, a bad definition, a screen that made you stop and think.

Requirements

• iPhone running iOS 17 or later.
• About 150 MB of storage: the whole dictionary lives on your phone and works offline.
• No account needed. Sign in only if you want your words synced between devices.
