Verdict

The call

The clearest difference is price: Zima Client at Free against KumaAlert's $3.99. Zima Client also leads on rating (4.8 vs 4.3) and ratings volume (197 vs 11). KumaAlert's advantage is update cadence (every 4 days vs every 2 weeks). On review sentiment, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Zima Client holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Zima Client has 197 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 59% of Zima Client's written reviews are positive against 64% of KumaAlert's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Zima Client ships an update every 2 weeks, KumaAlert every 4 days. Both last shipped on October 10, 2026.
