# Chromatica Mark II vs JPG Optimizer PRO

The clearest difference is rating: Chromatica Mark II at 4.1 against JPG Optimizer PRO's 3.3. Chromatica Mark II also leads on ratings volume (43 vs 3) and price ($1.99 vs $3.99). JPG Optimizer PRO's advantage is review sentiment (100% vs 61%). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Chromatica Mark II costs $1.99 and JPG Optimizer PRO $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

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.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
