The premiere periodic table app for iPhone, iPad, and Apple TV. Quickly reference any element and all the information you need. Search for elements by on classification, phase, orbital, mass, or number. Dynamic filters help you understand periodic trends, like electronegativity, at a glance. Dive even deeper to get standard, frequently-used data points such as mass, electronegativity, radius, radioactivity, electron configuration, and more. LEARN Each element prominently features: • Symbol, name, and number • Atomic mass • Electronegativity • Electron configuration • Atomic radius • Melting and boiling points • Year of discovery • State at STP • Radioactivity Elements are also accompanied by discussions on its uses, discovery, and more. You can quickly find more information and publications about each element via links to Wikipedia, Science Direct®, and the American Chemical Society®. EXPLORE The periodic table is laid out in a clear, concise manner that adapts to the size of your screen. No more squinting at blurry images of the periodic table from web searches. Beautiful color-coding helps you quickly distinguish element classifications, phases at STP, electronegativity, and atomic radius. Trends and filtering help students who are learning chemistry to visualize patterns. SOLUBILITY CALCUALTOR A built in solubility calculator* answers all your, "is this soluble in that", questions. Just specify a solvent and a solute to check their compatibility. A solubility lookup table is also available for cross-referencing multiple combinations. VISUALIZATIONS See beautiful depictions of elements from raw to processed, and in other forms. The extensive library of images help you understand what your lab samples should look like, or may be helpful to students learning about chemistry.* SEARCH Search for elements by name, symbol, mass, or number from within Elementium™ or via Spotlight. Results are shown directly on the periodic table. Need faster access to element information? Search directly from Spotlight on the lock screen or home screen of your device. BOHR MODELS Animated Bohr models for each element help visualize how electrons are oriented around the nucleus.* WRITE & REPORT Academics and students writing reports and using data frequently in the classroom or the lab can simply tap on an aspect of an element to export its information.* HOME SCREEN WIDGETS Add the Periodic Table widget to your home screen for quick and easy reference to the Periodic Table. Or, try out the "random element" widget which is useful for students.

Discover the full potential of Radiacode, a device designed for smart, flexible, and efficient operations, which transforms into an even more powerful tool when paired with Radiacode application, thereby enhancing device capabilities in radiation monitoring and data analysis. INTERACTIVE DASHBOARD Experience a user-friendly, real-time dashboard that displays comprehensive gamma energy and source analysis metrics, offering seamless navigation across all tools. SEARCHER The feature introduces an advanced ionizing radiation search function, equipped with an optimal averaging algorithm that enhances data processing and significantly improves responsiveness, providing users with precise and efficient real-time monitoring of radiation levels across diverse environments. SIGNALISATION The feature enhances the application with critical safety tools, activating alarms when detected radiation surpasses preset limits and providing users the flexibility to deactivate these alerts, ensuring a comprehensive approach to radiation monitoring and response. GAMMA SPECTROMETRY AND ISOTOPE VISUALIZATION Radiacode uniquely visualizes isotopes by interpreting the radiation spectrum, revealing varied gamma energy levels and enabling precise discrimination between different radiation elements for an engaging analytical experience. Visualize isotopes such as Radium-226 and Cesium-137 with ease, revealing varied gamma energy levels for a thorough understanding of different radiation elements, using technology previously exclusive to expensive laboratory equipment, now available in a portable, cost-effective format.

 SPECTROGRAM The spectrogram feature enhances data visualization and analysis in radiation spectrometry. It allows users to view the distribution of gamma radiation intensity across various energy levels in a visual format, making it easier to analyze and interpret radiation data. This function provides a detailed visual representation of the radiation spectrum, improving the ability to monitor and understand variations in radiation levels over time.
 DOSE MONITOR
 Monitor your radiation exposure throughout the day with a clear and intuitive overview of your accumulated dose. Track how your exposure evolves over time, identify spikes, and compare your data against reference safety levels for better awareness and control.
 The system automatically subtracts background radiation for improved accuracy and synchronizes environmental data via Radiaverse based on your location. Advanced algorithms ensure continuity by estimating exposure even when the device is not actively connected.
 Customize your monitoring experience by adjusting reference levels, selecting time ranges, and switching between total dose and above-background views. A detailed history chart allows you to manage sessions and refine your personal exposure data. FOOD CONTAMINATION Radiacode offers a specialized mode for detecting Cesium-137 in food products and liquid samples, using technology similar to laboratory analysis in a compact, easy-to-use format. Check seafood, berries, mushrooms, dairy, and meat for traces of Cs-137, compare results with safety limits, and ensure greater confidence in everyday food safety. With optional accessories such as a Marinelli beaker, Radiacode makes advanced contamination checks simple and accessible. RADIOLOGICAL MAPPING Explore the captivating feature of recording radiation measurements directly on Google Maps, where tracks are vividly plotted with color-coded points, each representing the exposure rate at specific locations. 

EVENTS The Events section allows alarms to function and register as events when set radiation levels are exceeded. It records the duration of the event and displays the limit level values for the period of the event. This section also includes the display of various system events for comprehensive monitoring. Radiacode is an excellent tool for scientific experimentation, research and safety.

Verdict

The call

The clearest difference is in-app purchases: Radiacode at none against Elementium's 9. Elementium's advantage is rating (4.6 vs 4.2) and update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
