Best Offline Vocabulary Apps in 2026

TL;DR — If you need to study with no connection — on a plane, a subway, or off-grid — the apps worth considering in 2026 are Lingufy, Anki, Drops, Memrise, and Duolingo. They differ a lot in how much works offline. Lingufy and Anki are the only ones that run essentially everything offline, including their spaced-repetition scheduling.

What "offline" really means for a vocabulary app

Most apps advertise some offline support, but the details matter. Ask three questions:

1. Is the content stored on-device? You should be able to study words, examples, and pronunciations with airplane mode on.
2. Does spaced repetition run locally? Good scheduling is computed from your review history. If that lives only in the cloud, your reviews stall offline.
3. Does progress sync later? Offline study is only useful if it merges cleanly once you reconnect.

An app that needs the network to fetch the next word isn't really an offline app — it's an online app with a cache.

The best offline vocabulary apps, compared

A few honest notes on the trade-offs:

• Lingufy is purpose-built for vocabulary: 5000+ words per language with translations, examples, and pronunciations stored locally, spaced repetition computed on-device, and home-screen widgets so you review without even opening the app. It's the most complete offline-first option for words specifically.
• Anki is the most flexible tool here and fully offline, but you assemble or download decks yourself and the interface is utilitarian. Great if you want to engineer your own system.
• Drops is polished and fun for short bursts, but its visual drills aren't true spaced repetition and the free tier is time-limited.
• Memrise shines for hearing words in real use, but the best features lean on streaming video, which needs a connection.
• Duolingo is excellent for staying motivated as a beginner, though offline lessons are limited and it teaches through courses rather than a dedicated vocabulary engine.

How to choose

• You want words to stick long-term: pick an app with real on-device spaced repetition — Lingufy or Anki.
• You want it to just work, beautifully, offline: Lingufy.
• You want total control and don't mind setup: Anki.
• You want quick, playful sessions: Drops.

Key takeaways

• "Offline" varies widely — check that both content and spaced repetition work without a connection.
• Lingufy and Anki are the only options here that run virtually everything offline.
• For offline vocabulary specifically, Lingufy offers the most complete out-of-the-box experience.
