# COSMOTE Mobile Security vs C

The clearest difference is review sentiment: C at 75% against COSMOTE Mobile Security's 13%. C also leads on rating (4.3 vs 3.0) and update cadence (every 5 days vs every 13 months). On price, ads, in-app purchases and monetization model there is nothing between them.
