ReceptionRating · Positive reviews · Number of ratings

Chromatica Mark II holds the better App Store score, 4.1 against 3.3. That said, the two scores are not equally well evidenced: Chromatica Mark II has 43 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 61% of Chromatica Mark II's written reviews are positive against 100% of JPG Optimizer PRO'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 November 2, 2026 and November 3, 2026 respectively.
