# Molecules vs Atomizer AR

The clearest difference is in-app purchases: Molecules at none against Atomizer AR's 4. Molecules also leads on ratings volume (166 vs 3). Atomizer AR's advantage is review sentiment (100% vs 65%) and rating (4.0 vs 3.6). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Atomizer AR sells 4 in-app purchases, starting at $1.99 per month. Molecules asks for nothing beyond the download.

Atomizer AR holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: Molecules has 166 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 65% of Molecules's written reviews are positive against 100% of Atomizer AR's.

Molecules ships an update every 2 months, Atomizer AR every 4 weeks. The most recent releases landed on September 29, 2026 and September 24, 2026 respectively.
