# Lost Chickens vs One By One

The clearest difference is rating: One By One at 4.8 against Lost Chickens's 3.0. One By One also leads on ratings volume (77 vs 2). Lost Chickens's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Lost Chickens sells 7 one-off in-app purchases and One By One sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

One By One holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: One By One has 77 ratings behind it against 2, so its average is the more settled of the two.
