Radioactive Decay Simulator vs Nuke Simulator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Radioactive Decay Simulator
This educational tool simulates radioactive decay for a group of atoms. Users can choose preset atoms or input custom half-lives to observe decay in real-time graphs. The simulator allows for adjustments in atom count and speed for efficient analysis.
- Emulates radioactive decay
- Select preset or custom atoms
- Adjust atom count
- Real-time decay graphs
- Adjustable simulation speed

The Radioactive Decay Simulator emulates the radioactive decay of a group of like atoms. Users are able to select from a range of preset atoms, or enter the half-life of a specific atom that they wish to simulate. By adjusting the number of atoms, users are able to determine how even with a large number of atoms, the randomness of radioactive decay can be modeled. Users are able to observe the both number of decayed atoms as well as the number of non-decayed atoms remaining in a real time graph. The simulator can be sped up to allow atoms with a longer half-life to be analyzed quickly.
Nuke Simulator
Simulate nuclear explosions to understand their destructive effects and calculate blast radii and fallout zones. Learn about historical weapons and their yields for educational and awareness purposes.
- Nuclear explosion simulation
- Calculate blast radius
- Estimate fallout zones
- Analyze casualty numbers
- Includes historical weapons data
- Educational awareness tool

The Nuclear Bomb Simulator is a free app designed to calculate the areas affected by a nuclear explosion based on the nuclear explosion formula. This app is suitable for those who wish to learn about the destructive effects of nuclear explosions and may be useful for evacuation planning. The app can calculate the approximate radiation radius and possible number of casualties based on a list of existing or past weapons and their yields, such as Fat Man, Little Boy, Tsar Bomba, and 28 other weapons with their respective yields. The development of this app is primarily for educational and awareness purposes. We hope for world peace and the preservation of our planet!

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
