Verdict
The clearest difference is review sentiment: CNS+ at 100% against MedOne's 22%. CNS+ also leads on rating (5.0 vs 4.5) and monetization model (free vs free with in-app purchases). MedOne's advantage is ratings volume (135 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.
