ReceptionRating · Positive reviews · Number of ratings

Zinier holds the better App Store score, 2.7 against 2.0. That said, the two scores are not equally well evidenced: Zinier has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 27% of Zinier's written reviews are positive against 60% of Dev Calc's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 30, 2026 and October 7, 2026 respectively.
