# aa 2 vs Unicorn Evolution Simulator

The clearest difference is review sentiment: Unicorn Evolution Simulator at 91% against aa 2's 41%. Unicorn Evolution Simulator also leads on rating (4.8 vs 3.5) and ratings volume (5.5K vs 624). aa 2's advantage is ads (none vs shown) and update cadence (fortnightly vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
