The call

ReceptionRating · Positive reviews · Number of ratings

Number Sum holds the better App Store score, 4.6 against 2.5. That said, the two scores are not equally well evidenced: Number Sum has 2.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 31% of Cross Digits Lite's written reviews are positive against 21% of Number Sum's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Cross Digits Lite ships an update every 11 months, Number Sum fortnightly. The most recent releases landed on October 31, 2026 and November 3, 2026 respectively.
