# OnePrep vs Genius Olympiad

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.

Both are free to download. OnePrep sells 24 in-app purchases, starting at $28.49 per 7 days. Genius Olympiad asks for nothing beyond the download.

Genius Olympiad holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OnePrep has 714 ratings behind it against 1, so its average is the more settled of the two.
