The clearest difference is rating: Служба Крови at 4.1 against INVITRO's 3.4. Служба Крови also leads on iOS requirement (12.0 vs 15.1). INVITRO's advantage is review sentiment (64% vs 28%) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Служба Крови holds the better App Store score, 4.1 against 3.4. Both are backed by a comparable volume of ratings — 23 and 87 respectively. Written reviews complicate that: 28% of Служба Крови's written reviews are positive against 64% of INVITRO's, so the app with the better star average is not the one people write more warmly about.
