# Splash Math vs Natulang

The clearest difference is review sentiment: Natulang at 90% against Splash Math's 63%. Natulang also leads on rating (4.8 vs 4.6) and update cadence (every 5 days vs every 3 weeks). Splash Math's advantage is ratings volume (4.5K vs 426) and iOS requirement (13.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Splash Math sells 9 in-app purchases, starting at $9.99 per month and Natulang sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Natulang holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Splash Math has 4.5K ratings behind it against 426, so its average is the more settled of the two. Written reviews point the same way: 63% of Splash Math's written reviews are positive against 90% of Natulang's.

Splash Math ships an update every 3 weeks, Natulang every 5 days. The most recent releases landed on November 8, 2026 and November 7, 2026 respectively.
