# Atomic vs Ro

The clearest difference is price: Atomic at Free against Ro's $0.99. Atomic also leads on ratings volume (34 vs 3) and update cadence (every 10 days vs every 3 weeks). Ro's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 90%). On rating, ads, device support and iOS requirement there is nothing between them.

Atomic is free to download; Ro costs $0.99 up front. Atomic sells 1 one-off in-app purchase. Ro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Atomic against 5.0 for Ro. That said, the two scores are not equally well evidenced: Atomic has 34 ratings behind it against 3, so its average is the more settled of the two. Written reviews are what separate them: 90% of Atomic's written reviews are positive against 100% of Ro's.

Atomic ships an update every 10 days, Ro every 3 weeks. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
