Nuclides vs Chemmory

Nuclides is a professional reference and calculation toolkit for nuclear technology, radiation protection, nuclear medicine, reactor data, and education. Key features: 1. Look up elements and nuclides, including half-life, decay modes, parent and daughter nuclides, radiation energies, and emission probabilities. 2. Explore extended nuclear data, including excited levels, gamma transitions, electron data, fission yields, nuclear moments, and ENSDF evaluation information. 3. Simulate gamma spectra from nuclide gamma-ray data with controls for live time, energy resolution, background, dead-time loss, and related detector parameters. 4. Run decay calculations, activity estimation, dose-rate estimation, effective dose estimation, radiation dose comparison, and unit conversions. 5. Use theranostics dosimetry tools for time-activity data, cumulated activity, and simplified MIRD relationships. 6. Consult radiation safety atlas entries, radiopharmaceutical references, material densities, physical constants, binding-energy charts, toxicity information, and the INES scale. 7. Browse nuclear power plant data, operating records, advanced reactor references, and small modular reactor information. Nuclides is designed for professionals, students, and users who need fast nuclear data lookup, radiation calculations, and clear technical references.

Chemmory is a simple, engaging memory game that helps you learn chemical elements. Practice names, symbols, atomic numbers, valencies, atomic masses and more — you decide what to study. A unique hint system not only makes matching easier, it also reinforces recall so you remember faster. HOW IT WORKS Flip cards as in classic memory and match the correct pairs. Choose the content you want (e.g., names + symbols, valency, mass), and pick how much assistance you get from hints. Your best runs are saved locally so you can beat your own records. FEATURE HIGHLIGHTS • Memory mode with element cards (symbol, name, atomic number, etc.) • Configurable learning scope and hints • Several hidden mini-games for variety • Full localization of element names: Polish, English, Russian, Spanish, French, German • Sound effects and light animations • Local leaderboard and stats • Works fully offline, no ads, no tracking • Supports older iPhones WHO IS IT FOR? Students preparing for tests, teachers looking for a quick warm-up, and younger players who enjoy bite-sized learning. Use Chemmory for daily practice, quick quizzes, or revising the periodic table on the go. PRIVACY Chemmory works offline and does not collect personal data. Scores and settings are stored on your device only. Have fun and happy learning!
