# DxO ONE vs Cobalt Image

The clearest difference is rating: DxO ONE at 3.6 against Cobalt Image's 2.3. DxO ONE also leads on in-app purchases (none vs 3) and ratings volume (35 vs 6). Cobalt Image's advantage is update cadence (every 5 days vs every 6 weeks) and review sentiment (56% vs 47%). On price and ads there is nothing between them.

Both are free to download. Cobalt Image sells 3 in-app purchases, starting at $3.49 per month. DxO ONE asks for nothing beyond the download.

DxO ONE holds the better App Store score, 3.6 against 2.3. That said, the two scores are not equally well evidenced: DxO ONE has 35 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 47% of DxO ONE's written reviews are positive against 56% of Cobalt Image's, so the app with the better star average is not the one people write more warmly about.

DxO ONE ships an update every 6 weeks, Cobalt Image every 5 days. The most recent releases landed on October 7, 2026 and October 8, 2026 respectively.
