Verdict
The clearest difference is in-app purchases: Fish IO at none against Count Master Zone's 6. Fish IO also leads on review sentiment (39% vs 16%). Count Master Zone's advantage is rating (4.6 vs 4.2) and update cadence (weekly vs every 6 weeks). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Count Master Zone sells 6 one-off in-app purchases. Fish IO asks for nothing beyond the download.
Count Master Zone holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Count Master Zone has 6.9K ratings behind it against 731, so its average is the more settled of the two. Written reviews complicate that: 39% of Fish IO's written reviews are positive against 16% of Count Master Zone's, so the app with the better star average is not the one people write more warmly about.
Fish IO ships an update every 6 weeks, Count Master Zone weekly. Both last shipped on October 30, 2026.
