Verdict
The clearest difference is review sentiment: Particle Zoo at 81% against Physics AI's 25%. Particle Zoo also leads on in-app purchases (none vs 2) and ads (none vs shown). Physics AI's advantage is rating (4.5 vs 3.9) and ratings volume (289 vs 48). On price, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Physics AI sells 2 in-app purchases, starting at $5.99 per 7 days. Particle Zoo asks for nothing beyond the download.
Physics AI holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Physics AI has 289 ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 81% of Particle Zoo's written reviews are positive against 25% of Physics AI'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, Physics AI fortnightly. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
