# Particle Zoo vs Vector Field

The clearest difference is rating: Vector Field at 4.5 against Particle Zoo's 3.9. Particle Zoo's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (48 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Vector Field holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Particle Zoo has 48 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 81% of Particle Zoo's written reviews are positive against 73% of Vector Field's, so the app with the better star average is not the one people write more warmly about.

Particle Zoo ships an update every 3 weeks, Vector Field every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
