Word Keeper: Learn Vocabulary

Learn new words with offline translation, smart practice and custom word lists

Word Keeper is a vocabulary learning app that helps you learn new words, build your personal vocabulary, and remember words through regular practice. Save and organize words into custom word lists, translate them instantly offline, and practice vocabulary in five different ways — no internet required.
Learn vocabulary your way
• Offline translation. Translate words directly on your device without an internet connection. The translation model downloads once and works anywhere — on a plane, underground, while traveling, or abroad.
• Create your own word lists. Organize vocabulary for work, travel, language learning, or any topic. One word can belong to multiple sections, while “All” keeps your complete vocabulary in one place.
• Five vocabulary practice modes. Practice translation, type the correct word, build words letter by letter, match word pairs against the clock, or use smart practice to focus on vocabulary that needs more review.
• Remember new words. Regular review helps you practice difficult words and build your vocabulary over time.
• Track your learning progress. Daily goals, practice streaks, and achievements help you stay consistent.
• Your vocabulary stays with you. Your word lists are stored on your device, with optional backup to your own Google Drive.
