Verdict
The clearest difference is in-app purchases: Genius Olympiad at none against OnePrep's 24. Genius Olympiad also leads on ads (none vs shown) and rating (5.0 vs 4.7). OnePrep's advantage is ratings volume (714 vs 1). On price, update cadence, device support and iOS requirement there is nothing between them.
