Radioactive Decay Simulator vs Nuclide Chart
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.

Explore the world of atomic nuclei with the most advanced Nuclide Chart for iPad. This app offers a complete, interactive visualization of all known isotopes (over 3000), perfect for study, research, and teaching. Features: • Live Data: Direct connection to the IAEA (International Atomic Energy Agency) database for up-to-date physical values. • Interactive: Smoothly zoom and pan through the entire chart of nuclides. • Decay Chains: Visualize decay paths (Alpha, Beta, etc.) instantly – step-by-step or as a full chain. • Smart Search: Find isotopes quickly by symbol, mass, or name. • Advanced Filters: Filter by stability or decay mode (Alpha, Beta+, Beta-, Fission). • Detailed Info: Comprehensive data for every nuclide (Half-life, Spin, Binding Energy, Magnetic Moment, Atomic Mass). • Offline-Ready: All data is cached locally for instant access. Ideal for physicists, chemists, students, and anyone interested in nuclear science.

Verdict
The clearest difference is in-app purchases: Radioactive Decay Simulator at none against Nuclide Chart's 1. Radioactive Decay Simulator also leads on iOS requirement (9.3 vs 17.0). Nuclide Chart's advantage is update cadence (daily vs every 17 months). On price, ads and device support there is nothing between them.
