# TOPIK vs Polymath

The clearest difference is rating: Polymath at 5.0 against TOPIK's 4.5. Polymath also leads on review sentiment (100% vs 75%) and update cadence (every 3 days vs every 10 days). TOPIK's advantage is ratings volume (96 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. TOPIK sells 1 one-off in-app purchase 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 4.5. That said, the two scores are not equally well evidenced: TOPIK has 96 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of TOPIK's written reviews are positive against 100% of Polymath's.

TOPIK ships an update every 10 days, Polymath every 3 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
