# EPS TOPIK vs Polymath

The clearest difference is update cadence: Polymath at every 3 days against EPS TOPIK's every 5 weeks. Polymath also leads on rating (5.0 vs 4.7). EPS TOPIK's advantage is ratings volume (31 vs 1) and iOS requirement (15.0 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. EPS TOPIK sells 2 one-off in-app purchases and Polymath sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Polymath holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: EPS TOPIK has 31 ratings behind it against 1, so its average is the more settled of the two.

EPS TOPIK ships an update every 5 weeks, Polymath every 3 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
