# RespiRelax+ vs KMI 건강검진

The clearest difference is review sentiment: RespiRelax+ at 70% against KMI 건강검진's 17%. RespiRelax+ also leads on ratings volume (16 vs 1). KMI 건강검진's advantage is rating (5.0 vs 4.1) and iOS requirement (13.0 vs 15.6). 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.

KMI 건강검진 holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: RespiRelax+ has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 70% of RespiRelax+'s written reviews are positive against 17% of KMI 건강검진's, so the app with the better star average is not the one people write more warmly about.

RespiRelax+ ships an update every 3 weeks, KMI 건강검진 monthly. The most recent releases landed on September 25, 2026 and September 10, 2026 respectively.
