# Kraepelin Training vs 1分間クレペリン計算

The clearest difference is rating: Kraepelin Training at 4.8 against 1分間クレペリン計算's 3.0. Kraepelin Training also leads on ratings volume (20 vs 1) and device support (3 vs 1). 1分間クレペリン計算's advantage is in-app purchases (none vs 1) and review sentiment (53% vs 25%). On price and ads there is nothing between them.

Both are free to download. Kraepelin Training sells 1 one-off in-app purchase. 1分間クレペリン計算 asks for nothing beyond the download.

Kraepelin Training holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Kraepelin Training has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Kraepelin Training's written reviews are positive against 53% of 1分間クレペリン計算's, so the app with the better star average is not the one people write more warmly about.

Kraepelin Training ships an update every 5 weeks, 1分間クレペリン計算 weekly. Both last shipped on November 3, 2026.
