Verdict
The clearest difference is in-app purchases: Atom Shell at none against Grav Box's 10. Atom Shell also leads on ads (none vs shown) and iOS requirement (9.0 vs 14.0). Grav Box's advantage is rating (4.8 vs 4.5) and ratings volume (26 vs 2). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Grav Box sells 10 one-off in-app purchases. Atom Shell asks for nothing beyond the download.
Grav Box holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Grav Box has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 96% of Grav Box's written reviews are positive against 100% of Atom Shell's, so the app with the better star average is not the one people write more warmly about.
Grav Box ships an update every 5 months, Atom Shell every 6 months. The most recent releases landed on September 17, 2026 and September 12, 2026 respectively.
