Nuclides vs Morse Master

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.

Morse code becomes easier to remember when you hear it, key it, and understand how its patterns connect. Morse Master is a hands-on learning game that helps you explore the Morse tree and build practical skill through guided lessons and repeated keying practice. New learners can start with an interactive introduction to dits (·) and dahs (—). If you already know the basics, adjust the speed and timing to create a practice setup that matches your level. Key features • Explore letter relationships on a visual Morse tree • Follow a guided, interactive introduction for beginners • Practice letters, numbers, or a combination of both • Build fluency with word-based repetition and Morse key input • Adjust WPM, dit/dah timing threshold, and word spacing • Practice with straight-key and iambic-paddle input styles • Customize sidetone, sound character, haptics, and Morse hints • Review learning progress, statistics, and personal records • Use the app in English or Korean • Optionally sign in with Apple or Google to sync learning progress Morse Master is designed for • Beginners learning Morse code for the first time • CW and amateur radio enthusiasts • Learners who want to turn memorized patterns into practical keying skill • Anyone working to improve speed and accuracy through regular practice No account is required for the core learning experience. Sign-in is optional and is only needed when you want to synchronize learning progress across devices. The iOS version is free and contains no ads, in-app purchases, or subscriptions.
