# UMC Care vs DIAG

The clearest difference is review sentiment: DIAG at 100% against UMC Care's 38%. UMC Care's advantage is rating (3.9 vs 3.7) and ratings volume (21 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

UMC Care holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: UMC Care has 21 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 38% of UMC Care's written reviews are positive against 100% of DIAG's, so the app with the better star average is not the one people write more warmly about.

UMC Care ships an update every 5 days, DIAG every 4 days. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
