LingvoNest

LingvoNest is an on-device translator designed for travel, study, and everyday reading when privacy and offline access matter. Type or paste text, choose a source and target language, and translate with downloadable local language models. Once a language pack is ready, translations run on your device without sending your text to a translation server.

The app keeps a local history of recent translations, lets you save useful phrases to a phrasebook, and gives you direct controls for downloading or removing language packs from LingvoNest's offline list. Wi-Fi-only downloads help manage larger first-time model installs, while automatic pack downloads can prepare missing languages during translation.

LingvoNest also includes local export and import tools so you can move your history, phrasebook, settings, and pack list with a JSON backup. Your translations, favorites, default language pair, and app settings are stored locally on your device with AsyncStorage.
