# KOBI vs Squishy Math Trail

The clearest difference is update cadence: Squishy Math Trail at every 2 days against KOBI's fortnightly. Squishy Math Trail also leads on rating (5.0 vs 4.7). KOBI's advantage is ratings volume (38 vs 4) and iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KOBI sells 10 in-app purchases, starting at $12.99 per month and Squishy Math Trail sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Squishy Math Trail holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: KOBI has 38 ratings behind it against 4, so its average is the more settled of the two.

KOBI ships an update fortnightly, Squishy Math Trail every 2 days. The most recent releases landed on October 14, 2026 and October 24, 2026 respectively.
