# rr vs Dog Merge Evolution

The clearest difference is rating: Dog Merge Evolution at 4.8 against rr's 4.1. Dog Merge Evolution also leads on review sentiment (92% vs 68%) and ratings volume (2.7K vs 84). rr's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. rr sells 3 one-off in-app purchases and Dog Merge Evolution sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
