# Fractal Generator vs Physarum

The clearest difference is review sentiment: Physarum at 100% against Fractal Generator's 60%. Physarum also leads on rating (4.8 vs 4.3) and update cadence (every 5 weeks vs every 3 months). Fractal Generator's advantage is iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fractal Generator sells 5 one-off in-app purchases and Physarum sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Physarum holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Physarum has 35 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 60% of Fractal Generator's written reviews are positive against 100% of Physarum's.

Fractal Generator ships an update every 3 months, Physarum every 5 weeks. The most recent releases landed on November 2, 2026 and November 8, 2026 respectively.
