# 縦式 vs Kingbox.

The clearest difference is review sentiment: 縦式 at 86% against Kingbox.'s 43%. 縦式 also leads on update cadence (every 3 days vs monthly) and ratings volume (57 vs 2). Kingbox.'s advantage is in-app purchases (none vs 7) and rating (5.0 vs 4.7). On price, ads and device support there is nothing between them.

Both are free to download. 縦式 sells 7 one-off in-app purchases. Kingbox. asks for nothing beyond the download.

Kingbox. holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 縦式 has 57 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 86% of 縦式's written reviews are positive against 43% of Kingbox.'s, so the app with the better star average is not the one people write more warmly about.

縦式 ships an update every 3 days, Kingbox. monthly. Both last shipped on October 18, 2026.
