# Atomizer AR vs Physarum

The clearest difference is rating: Physarum at 4.8 against Atomizer AR's 4.0. Physarum also leads on ratings volume (32 vs 3). Atomizer AR's advantage is update cadence (every 2 weeks vs every 5 weeks) and device support (6 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Atomizer AR sells 4 in-app purchases, starting at $1.99 per month 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 4.0. That said, the two scores are not equally well evidenced: Physarum has 32 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Atomizer AR ships an update every 2 weeks, Physarum every 5 weeks. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
