# DoodleMath vs Sumdog

The clearest difference is update cadence: DoodleMath at every 3 weeks against Sumdog's every 2 months. Sumdog's advantage is rating (4.2 vs 4.0) and ratings volume (1.6K vs 235). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. DoodleMath sells 11 in-app purchases, starting at $7.99 per month and Sumdog sells 1 in-app purchase, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Sumdog holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Sumdog has 1.6K ratings behind it against 235, so its average is the more settled of the two. Written reviews point the same way: 57% of DoodleMath's written reviews are positive against 64% of Sumdog's.

DoodleMath ships an update every 3 weeks, Sumdog every 2 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
