# ME2Go vs Mechanical Dictionary

The clearest difference is review sentiment: Mechanical Dictionary at 100% against ME2Go's 27%. Mechanical Dictionary also leads on rating (4.4 vs 3.0). ME2Go's advantage is ads (none vs shown) and update cadence (every 2 months vs every 9 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
