# OnePrep vs apush.app

The clearest difference is ads: apush.app at none against OnePrep's shown. apush.app also leads on rating (5.0 vs 4.7). OnePrep's advantage is ratings volume (753 vs 1) and iOS requirement (15.1 vs 17.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. OnePrep sells 10 in-app purchases, starting at $28.49 per 7 days and apush.app sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

apush.app holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OnePrep has 753 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on November 12, 2026 and November 5, 2026 respectively.
