# GACE Math Test Prep vs EthiScan

The clearest difference is rating: EthiScan at 5.0 against GACE Math Test Prep's 4.4. EthiScan also leads on update cadence (every 2 days vs every 9 months). GACE Math Test Prep's advantage is ratings volume (23 vs 3) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. GACE Math Test Prep sells 1 in-app purchase, starting at $9.99 per month and EthiScan sells 1 in-app purchase, starting at $14.99 per year. Whichever you choose, the download price is not the number that matters.

EthiScan holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: GACE Math Test Prep has 23 ratings behind it against 3, so its average is the more settled of the two.

GACE Math Test Prep ships an update every 9 months, EthiScan every 2 days. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
