# Slime.io vs Soul.io

The clearest difference is rating: Soul.io at 4.7 against Slime.io's 3.8. Soul.io also leads on ratings volume (8K vs 6). Slime.io's advantage is ads (none vs shown) and update cadence (fortnightly vs every 4 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Soul.io holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: Soul.io has 8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 67% of Slime.io's written reviews are positive against 53% of Soul.io's, so the app with the better star average is not the one people write more warmly about.

Slime.io ships an update fortnightly, Soul.io every 4 months. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
