Verdict

The call

The clearest difference is rating: Agar.io at 4.5 against Nebulous.io's 4.1. Agar.io also leads on ratings volume (221K vs 2.6K) and chart position (#162 vs unranked). Nebulous.io's advantage is review sentiment (54% vs 29%) and update cadence (every 2 weeks vs every 4 weeks). On price, ads, in-app purchases and monetization model 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 Nebulous.io sells 12 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 4.1. That said, the two scores are not equally well evidenced: Agar.io has 221K ratings behind it against 2.6K, so its average is the more settled of the two. Written reviews complicate that: 29% of Agar.io's written reviews are positive against 54% of Nebulous.io'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, Nebulous.io every 2 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
