# Agar.io vs Nebulous.io

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 (#166 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.

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.

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.

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.
