ReceptionRating · Positive reviews · Number of ratings

America's Test Kitchen holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: America's Test Kitchen has 18K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 71% of Serving Sizer recipe converter's written reviews are positive against 66% of America's Test Kitchen's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Serving Sizer recipe converter ships an update monthly, America's Test Kitchen fortnightly. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
