# 321! vs Time Twin

The clearest difference is rating: Time Twin at 5.0 against 321!'s 4.2. 321!'s advantage is ratings volume (32 vs 1) and iOS requirement (9.0 vs 12.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 321! sells 2 one-off in-app purchases and Time Twin sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Time Twin holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: 321! has 32 ratings behind it against 1, so its average is the more settled of the two.
