Dictionary Lab: Vocab Builder

Dictionary Lab: build your own dictionaries — one for every language, subject, or project.

Unlike other dictionary apps that just define words for you, Dictionary Lab is where YOU create the dictionary. Add the words that matter to you, group them however you want, and let scheduled reminders bring those words back to you — day after day — so they actually stick. Fully offline, no ads, no account.

Perfect for language learners, students, and professionals building specialized vocabulary.

✦ WHAT MAKES DICTIONARY LAB DIFFERENT

Most dictionary apps are one-way — they define words for you. Dictionary Lab flips that: you build the dictionary. Every word you add is one you actually care about, which is why it sticks.

Create as many custom dictionaries as you want:
- One for your Spanish class
- One for IELTS or TOEFL prep
- One for medical, legal or technical terms at work
- One for a novel you're writing or translating
- One for beautiful words you don't want to forget

Each dictionary is fully independent — its own words, its own reminder schedule, its own purpose.

✦ FEATURES

- Create unlimited custom dictionaries — organize by language, topic, or project
- Rich word entries: definitions, example sentences, and tags
