Verdict
The clearest difference is review sentiment: Carb Care at 100% against LibreLinkUp's 28%. Carb Care also leads on update cadence (every 4 weeks vs every 3 months) and rating (5.0 vs 4.8). LibreLinkUp's advantage is ratings volume (23K vs 4) and chart position (#93 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
