# Überdoodle lite vs Particle Simulation

The clearest difference is rating: Particle Simulation at 4.5 against Überdoodle lite's 1.9. Particle Simulation also leads on ads (none vs shown) and ratings volume (46 vs 8). Überdoodle lite's advantage is review sentiment (61% vs 25%) and in-app purchases (none vs 4). On price and device support there is nothing between them.

Both are free to download. Particle Simulation sells 4 in-app purchases, starting at $2.99 per 7 days. Überdoodle lite asks for nothing beyond the download.

Particle Simulation holds the better App Store score, 4.5 against 1.9. That said, the two scores are not equally well evidenced: Particle Simulation has 46 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 61% of Überdoodle lite's written reviews are positive against 25% of Particle Simulation's, so the app with the better star average is not the one people write more warmly about.

Überdoodle lite ships an update every 3 weeks, Particle Simulation every 7 months. The most recent releases landed on September 28, 2026 and September 9, 2026 respectively.
