# ru vs Agar.io

The clearest difference is rating: Agar.io at 4.5 against ru's 3.4. Agar.io also leads on ratings volume (221K vs 51) and update cadence (every 4 weeks vs every 4 months). ru's advantage is ads (none vs shown) and review sentiment (46% vs 28%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ru sells 1 one-off in-app purchase and Agar.io sells 10 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Agar.io holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: Agar.io has 221K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 46% of ru's written reviews are positive against 28% of Agar.io's, so the app with the better star average is not the one people write more warmly about.

ru ships an update every 4 months, Agar.io every 4 weeks. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
