Lexicon

Lexicon Help

Everything you need to know about building and managing your vocabulary with Lexicon.

Lexicon is still in development and isn't on the App Store yet. This page previews how it will work once it ships.

Getting started

Once Lexicon is released, you'll be able to start adding entries immediately — no account required.

Quick start steps

  1. Tap the + button to add your first entry
  2. Enter a word, definition, and optional notes
  3. Add tags, part of speech, and IPA if relevant
  4. Tap Save — your entry is stored locally on your device

To sync across devices, you will need an account, once cloud sync is available. See the Cloud sync section for setup instructions.

Adding and editing entries

Each lexicon entry can contain a word or phrase, one or more definitions, notes, tags, part of speech, IPA pronunciation, and links to related entries.

Entry fields

  • Word / headword — the main word or phrase
  • Definition — one or more definitions
  • Part of speech — noun, verb, adjective, etc.
  • IPA — pronunciation in International Phonetic Alphabet
  • Tags — custom labels for organisation
  • Notes — free-text field for examples, context, memory aids
  • Linked entries — synonyms, antonyms, derivations

Undo / redo

All edits support full undo and redo. Shake your device or use the undo button in the toolbar to step back through changes.

Tags and categories

Tags are free-form labels you create yourself. Common uses include part of speech, thematic categories (food, travel, emotion), difficulty level, or source language.

To create a tag, type it directly into the tag field on any entry. Tags are auto-completed from tags you have used before. You can filter by tag from the main list view using the filter bar.

There is no limit on the number of tags per entry.

Cloud sync

Cloud sync is planned as an optional addition once it's built. It will sync your entire lexicon — entries, tags, IPA, notes, and linked entries — across all Apple devices signed into your Luukza account.

Setting up sync

  1. Create your Luukza account using email or Apple Sign In
  2. Open Settings in Lexicon and tap Enable Cloud Sync
  3. Your lexicon will sync automatically when connected to the internet

Note: The first sync may take a few minutes if you have a large lexicon. Keep the app open during the initial sync.

Export and import your lexicon

You can export your entire lexicon as a JSON file at any time. This is the recommended way to back up your data or move between devices without sync.

Exporting

Go to Settings → Export Lexicon. Choose JSON format. You can share the file to Files, Mail, or any other app.

Importing

Go to Settings → Import Lexicon. Select your JSON file. You can choose to merge with your existing lexicon or replace it entirely. Duplicate entries (matched by headword) are skipped by default.

Pronunciation

IPA notation

Any entry can include an IPA pronunciation string. Lexicon displays this alongside the headword in the entry view. IPA characters can be typed directly or pasted from any IPA keyboard app.

Audio pronunciation

Once built, you'll be able to record or upload an audio clip for any entry, stored privately and synced to your account. To add audio, open an entry and tap the microphone icon next to the IPA field.

Flashcards and quiz mode

Flashcard mode turns your lexicon into a spaced-repetition study deck. Cards are generated automatically from your entries.

Modes

  • Word → Definition — see the word, recall the meaning
  • Definition → Word — see the definition, recall the word
  • IPA → Word — hear/read the pronunciation, recall the spelling

Confidence scores per entry, along with custom lesson builders and image cloze, are planned as more advanced additions later on.

Frequently asked questions

Can I use Lexicon for multiple languages at once?

Yes. There is no language restriction. You can mix languages in one lexicon, or create separate lexicons if you prefer. (Multiple lexicons are a planned future feature.)

Is there a limit on the number of entries?

No limit is planned, on-device or once cloud sync exists.

Can I use Lexicon offline?

Yes. Lexicon is offline-first. All your data is stored locally and available without an internet connection. Sync happens in the background when connectivity is available.

How do I report a bug or suggest a feature?

Use the in-app feedback button in Settings, or visit luukza.com/contact.
