1983 is a vocabulary map. Every word in the catalogue is placed in two dimensions: intensity (from mild to extreme) and nuance (the axis that distinguishes near-synonyms). Open a cluster — say, "Shades of Anger" — and you see the entire neighborhood at a glance: irked vs incandescent vs apoplectic, all mapped, all clickable. The catalogue is curated, not crawled: 1,863 words across 208 clusters and 15 superclusters, each definition hand-written, each example pulled from public-domain literature or anchored in mythology. No filler, no near-duplicates. What's inside: THE SHELF — Browse the full map by supercluster, then drill into clusters of 4 to 30 words. Toggle the nuance axis to re-arrange the cluster from a different angle. THE DRILL — Three quiz modes: definition (which word means X), nuance (which option has the right shade), and intensity (rank by strength). Questions adapt to what you've missed. THE RECORD — A 90-day heatmap of practice, a list of your most-missed words, and a mastery archive that fills in as you progress. Master a cluster and earn a printed patch. THE DAILY — A Word of the Day widget for your home screen, refreshed every morning from the catalogue. Tap it to jump straight to the card. 7-day free trial, then $5.99/month auto-renewing subscription. Cancel anytime in Settings. Apple Sign In, Google Sign In, or email signup. Built for writers, GRE/SAT candidates, ESL speakers ready for the upper register, and anyone who got tired of looking words up only to forget them the next day.

Verdict
The clearest difference is rating: Schema at 5.0 against Vocabulary Builder's 3.0. Schema also leads on monetization model (freemium vs subscription). Vocabulary Builder's advantage is update cadence (every 3 days vs every 9 days) and iOS requirement (15.0 vs 18.0). On price, ratings volume, ads and in-app purchases there is nothing between them.
