Where do the 958 GRE words come from?
Curated and deduplicated from 5 top GRE prep sources including Barron’s High Frequency list, Vocabulary.com’s Roadmap series, and quantitative reasoning terms. Organized into 5 progressive study blocks.
How does app blocking work on iOS?
PrepLockin uses Apple’s official FamilyControls framework — the same Screen Time technology built into every iPhone. You choose which apps to block. When you tap a blocked app, a branded shield appears with a 5-question vocab quiz. Answer correctly and the app unlocks. All data stays on your device.
Can I use it without blocking apps?
Yes. Flashcards, games, widgets, spaced repetition, streaks, and heatmap all work independently. But students who enable blocking learn significantly faster.
What happens after the free trial?
Everything is fully unlocked during the 7-day trial. Cancel in iPhone Settings before Day 8 and you pay nothing.
Is this enough for the GRE verbal section?
Our 958 words cover all the high-frequency vocabulary tested on the GRE. Combined with spaced repetition and daily practice through app blocking, most students see significant score improvements in 8–10 weeks.
