# 7 vs Japan

The clearest difference is in-app purchases: 7 at none against Japan's 1. 7 also leads on ads (none vs shown) and ratings volume (320 vs 19). Japan's advantage is update cadence (weekly vs every 3 months) and iOS requirement (16.2 vs 18.0). On price, rating and device support there is nothing between them.

Both are free to download. Japan sells 1 one-off in-app purchase. 7 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for 7 against 4.7 for Japan. That said, the two scores are not equally well evidenced: 7 has 320 ratings behind it against 19, so its average is the more settled of the two.

7 ships an update every 3 months, Japan weekly. Both last shipped on October 27, 2026.
