Verdict

The call

The clearest difference is review sentiment: Crazy Kaiju at 100% against Fish Go.io 2's 37%. Crazy Kaiju also leads on ratings volume (1.8K vs 271). Fish Go.io 2's advantage is rating (4.7 vs 4.5) and update cadence (monthly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Fish Go.io 2 holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Crazy Kaiju has 1.8K ratings behind it against 271, so its average is the more settled of the two. Written reviews complicate that: 100% of Crazy Kaiju's written reviews are positive against 37% of Fish Go.io 2's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Crazy Kaiju ships an update every 3 months, Fish Go.io 2 monthly. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
