Verdict

The call

The clearest difference is in-app purchases: GRE Vocabulary Builder at none against CGFM Study Guide's 2. GRE Vocabulary Builder also leads on ratings volume (113 vs 1) and iOS requirement (13.0 vs 17.0). CGFM Study Guide's advantage is rating (5.0 vs 4.6) and update cadence (every 2 months vs every 4 months). On price, ads and device support there is nothing between them.
