Verdict
Polygence and OnePrep both sit at 4.7 stars, but that hides the real split: 88% of Polygence's written reviews are positive against 41% of OnePrep's. Polygence also leads on in-app purchases (none vs 10) and ads (none vs shown). OnePrep's advantage is update cadence (every 5 days vs every 2 months) and ratings volume (753 vs 13). On price, rating, device support and iOS requirement there is nothing between them.
