ReceptionRating · Positive reviews · Number of ratings

Number Sums holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Number Sums has 31K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of Quickfire Interactive's written reviews are positive against 26% of Number Sums's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Quickfire Interactive ships an update every 15 months, Number Sums every 2 months. The most recent releases landed on October 5, 2026 and October 16, 2026 respectively.
