2. Word of the Day ・ Vocabulary
Download:
Cost: Free Plan (Free), Premium Subscription (Monthly) ($2.99/month)
Word of the Day ・ Vocabulary is a fantastic app for expanding your vocabulary, boasting a rich collection of beautifully illustrated word stories and curated word lists. While users praise its effectiveness in learning new words ("I have learnt loads of new words"), some experience issues with audio pronunciation (crashes, American accent difficulty) and notifications. Despite these glitches (initially impacting the rating), the app's extensive word archive and potential for user-suggested words ("option to suggest future words") make it a valuable tool for daily vocabulary building, although interstitial ads and the lack of in-widget definitions remain minor drawbacks. I chose it for its engaging format and the sheer number of new words I've learned, outweighing the occasional technical hiccup.

Key Features:
- Daily curated word definitions and stories.
- Personalized word collections for review.
