Verdict

The call

The clearest difference is rating: Agar.io at 4.5 against Stack Rush's 3.7. Agar.io also leads on ratings volume (221K vs 3) and chart position (#175 vs unranked). On price, review sentiment, update cadence and ads there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Agar.io sells 10 in-app purchases, starting at $7.99 per 7 days and Stack Rush sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Agar.io holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Agar.io has 221K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 28% of Agar.io's written reviews are positive against 33% of Stack Rush's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Agar.io ships an update every 4 weeks, Stack Rush fortnightly. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
