# GRE Vocabulary Builder vs CQA Exam Study Guide

The clearest difference is in-app purchases: GRE Vocabulary Builder at none against CQA Exam Study Guide's 2. GRE Vocabulary Builder also leads on ratings volume (113 vs 1) and iOS requirement (13.0 vs 15.0). CQA Exam Study Guide's advantage is rating (5.0 vs 4.6) and update cadence (every 3 weeks vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. CQA Exam Study Guide sells 2 in-app purchases, starting at $1.99 per month. GRE Vocabulary Builder asks for nothing beyond the download.

CQA Exam Study Guide holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: GRE Vocabulary Builder has 113 ratings behind it against 1, so its average is the more settled of the two.

GRE Vocabulary Builder ships an update every 4 months, CQA Exam Study Guide every 3 weeks. The most recent releases landed on September 26, 2026 and October 15, 2026 respectively.
