# Cross Digits Lite vs Number Sum

The clearest difference is rating: Number Sum at 4.6 against Cross Digits Lite's 2.5. Number Sum also leads on update cadence (fortnightly vs every 11 months) and ratings volume (2.3K vs 6). Cross Digits Lite's advantage is in-app purchases (none vs 5) and review sentiment (31% vs 21%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Number Sum sells 5 one-off in-app purchases. Cross Digits Lite asks for nothing beyond the download.

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.

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.
