# RiddleSum vs Math Grid

The clearest difference is review sentiment: Math Grid at 70% against RiddleSum's 0%. Math Grid also leads on ratings volume (5.6K vs 10) and rating (4.9 vs 4.6). RiddleSum's advantage is monetization model (ad-supported vs free with in-app purchases). On price, ads and in-app purchases there is nothing between them.

Both are free to download. RiddleSum sells 1 one-off in-app purchase and Math Grid sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Math Grid holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Math Grid has 5.6K ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 0% of RiddleSum's written reviews are positive against 70% of Math Grid's.

RiddleSum ships an update every 2 months, Math Grid fortnightly. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
