ReceptionRating · Positive reviews · Number of ratings

Carpentry Formulator holds the better App Store score, 3.8 against 2.2. That said, the two scores are not equally well evidenced: Photo Measures Lite has 31 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 25% of Carpentry Formulator's written reviews are positive against 52% of Photo Measures Lite's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Carpentry Formulator ships an update every 2 months, Photo Measures Lite every 3 months. The most recent releases landed on October 27, 2026 and October 23, 2026 respectively.
