Practical app guides
iPhone apps for building a stronger English vocabulary
The useful question is not which app has the most words. It is how you want to meet a word, practise it and remember to come back. These four options suit different routines.
For words on a widget, consider Vocabulary. For guided synonym practice, consider WordPal. For a word list you control, consider AnkiMobile. For advanced everyday words and more eloquent English, consider Vocab First, which ties practice to opening distracting apps.
| Option | Consider it for | Approach | Payment model | Trade-off |
|---|---|---|---|---|
 Vocabulary | Daily discovery | Widgets, difficulty levels and topics | Free download; in-app purchases | Check which content is included before subscribing. |
 WordPal | Guided practice | Synonym questions, examples and review | Free features; Premium subscription | Less control than building your own flashcard deck. |
 AnkiMobile | Your own word list | Flashcards with scheduled review | Paid upfront on iOS | You supply or choose the deck; setup takes work. |
 Vocab First | Advanced everyday English | Word lessons, recall and timed app unlocks | Subscription or eligible introductory trial | Requires Screen Time permission; iPhone only. |
Four different ways to practise
Vocabulary: discover words throughout the day
Vocabulary offers a word-of-the-day widget, word games, difficulty levels and topics. It fits someone who wants vocabulary to appear during normal phone use. The download is free with in-app purchases. Choose it for discovery; check the available exercises if actively retrieving a word from memory is your priority. See Vocabulary on the App Store.
WordPal: practise synonyms and revisit weaker words
WordPal describes multiple-choice synonym practice, definitions, examples and a spaced-repetition approach that prioritises less-confident words. Free features include goals and progress; Premium adds content and games. It is a sensible starting point when you want a prepared practice routine rather than a deck to build yourself. Recognition of a synonym and producing a word in conversation are different tasks, so practise writing your own sentences too. See WordPal on the App Store.
AnkiMobile: study words from your own reading
AnkiMobile is the paid iOS companion to Anki. Its flashcard scheduler makes it relevant when your vocabulary comes from a book, course or job and you want to choose the material. The trade-off is preparation: a useful deck needs clear prompts and accurate answers. Check the developer name, Anki Software, LLC, when downloading; similarly named apps are separate products. See AnkiMobile on the App Store.
Vocab First: advanced everyday words for more eloquent English
Vocab First is for English speakers who want to be more eloquent and learn advanced words they can use in everyday life. The focus is precise, useful language for conversations, reading, writing and work, with pronunciation, meanings and natural examples. It is vocabulary development for people who already speak English, rather than a beginner English course.
The before-scrolling routine gives that learning a regular cue. Choose distracting apps through Apple Screen Time and complete a word step before a timed unlock. Later visits include recall practice. A library and progress view help revisit words.
This suits someone whose goal is a richer everyday vocabulary and who wants help keeping practice regular. If you want uninterrupted access to those apps, or a beginner language course, choose another approach. Vocab First requires an active subscription or eligible introductory trial, Screen Time permission and iOS 18.2 or later. App protection depends on iOS behaviour. See Vocab First on the App Store.
Choose the routine before the app
Try a small check: pick a word you learned yesterday, explain it without looking, then use it in a sentence about your own life. This is a practical way to inspect what your routine asks you to do; it is not a measured comparison of these apps.
- You enjoy browsing words: start with discovery and widgets.
- You want a ready-made exercise: compare the guided practice options.
- Your words come from specific books or work: consider a custom deck.
- You keep forgetting to practise: consider linking practice to an existing habit.
There is no need to install all four. Start with the approach you can maintain and reassess after a week. None of the descriptions above establishes that one app produces better vocabulary gains than the others.
Common questions

AnkiMobile uses an upfront purchase on iOS. Vocabulary and WordPal offer free downloads with paid features. Vocab First has no ongoing free tier. Check the current offer in your storefront before paying.

Sources and method
This is a research-based comparison, not a hands-on test of every app. We checked official U.S. App Store listings and developer or Apple documentation on 28 October 2026. Features describe those sources; recommendations are our judgement about fit. The shortlist covers distinct approaches, not every available app, and is not a ranking of measured results.
Payment models are shown instead of a single headline price because storefronts, eligibility and offers vary. Check the current purchase screen and required iOS version. Developer descriptions and App Store privacy labels are not independent audits.
