Questions

Where do the 955 IELTS words come from?
Curated from official IELTS preparation materials, academic word lists, and frequency analysis of IELTS passages. Organized into 4 categories: Academic Writing, Reading Passages, Speaking Fluency, and Topic Vocabulary.
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 5-question vocab quiz appears. Answer correctly and the app unlocks. All data stays on your device.
Will this help me get a higher band score?
Vocabulary is a key scoring criterion across all IELTS sections. Our 955 words cover academic writing, reading passages, speaking fluency, and topic-specific terms. Students who master these words consistently score higher on the vocabulary component.
