# Radioactive Decay Simulator vs Nuke Simulator

The clearest difference is review sentiment: Radioactive Decay Simulator at 100% against Nuke Simulator's 51%. Radioactive Decay Simulator also leads on in-app purchases (none vs 1) and ads (none vs shown). Nuke Simulator's advantage is rating (4.6 vs 4.0) and update cadence (every 2 months vs every 17 months). On price and device support there is nothing between them.

Both are free to download. Nuke Simulator sells 1 one-off in-app purchase. Radioactive Decay Simulator asks for nothing beyond the download.

Nuke Simulator holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Nuke Simulator has 1K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Radioactive Decay Simulator's written reviews are positive against 51% of Nuke Simulator's, so the app with the better star average is not the one people write more warmly about.

Radioactive Decay Simulator ships an update every 17 months, Nuke Simulator every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
