Verdict
The clearest difference is ads: LogiPix at none against Number Sum's shown. LogiPix also leads on review sentiment (50% vs 21%) and monetization model (free vs free with in-app purchases). Number Sum's advantage is ratings volume (2.3K vs 6) and rating (4.6 vs 4.3). On price and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. LogiPix sells 4 one-off in-app purchases and Number Sum sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Number Sum holds the better App Store score, 4.6 against 4.3. 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: 50% of LogiPix'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.
LogiPix ships an update every 2 months, Number Sum fortnightly. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
