Changelog

Fixed

• The installed app icon now fills the home screen tile. Copies installed before this release keep the old icon until they are reinstalled.
• Disabled autocomplete in search field.
• Updated tinted cells text colors.
• Table correctly auto-fits on large screens.
• Don't cover menu with toasts.

Added

• Setting commands in the menu search: type "dark theme", "Fahrenheit", or "Ukrainian" to change a setting without opening Settings.
• Element shortcuts in the menu search:
  • An element's name, symbol, or atomic number opens its page.
  • Adding a section or property, as in "iron boiling point" or "Au radii", opens the right tab, then scrolls to and highlights it.
  • Adding a mass number, as in "iron 56", opens that isotope.

Changed

• The menu search understands natural wording and tolerates typos, so "table of nuclides" and "nucleodic table" both find the nuclides table.

Added

• Spectral analysis in the menu search, opening the element list with emission spectra shown.

Changed

• Each tab of an element page now has its own title and a description quoting its key values.
• More detailed page descriptions for search results and link previews.

Fixed

• Pages no longer flash without the menu, panels, or parts of the table while loading in Chromium-based browsers.

Added

• A solubility table charting 23 cations against 15 anions, with the formula, name, and solubility of every compound.
• A solubility table sheet in the print constructor, alongside the periodic table.
• An acid-base indicators page covering litmus, phenolphthalein, methyl orange, and universal indicator, with a draggable pH scale showing the color each one turns at any point from 0 to 14.
• A bottom navigation bar on phones and touch devices.
• A keyboard shortcuts list.
• Keyboard zoom on the nuclides table.
• Binding energy per nucleon and neutron and proton separation energies on nuclide pages.
• A color-coded spectral range on the emission spectrum, for narrowing it to a range of bands or to a single one.

Changed

• Zooming the periodic table with buttons or keyboard now applies instantly, without an animation.
• Revamped desktop and mobile menus.

Fixed

• Printed tinted cells now use the same text color as the interactive table.

Added

• Interactive periodic table in both the modern 18-column long form and the 8-group short form.
• Filtering by category, block, occurrence, biological role, electrical type, and magnetic ordering.
• A temperature slider showing the phase of every element at a chosen temperature.
• A heatmap overlay for any of the numeric properties.
• Pan and zoom on the table.
• Element detail pages covering:
  • General information.
  • Atomic properties with visualized Bohr model, electron configuration, radii, oxidation states, and crystal structure.
  • Thermodynamic properties with visualized phase and heating curve.
  • Electromagnetic properties with visualized spectroscopy.
  • Isotopes table.
• A searchable, sortable element list.
  • A trends page plotting any numeric property against atomic number.
• Side-by-side comparison of elements.
• A table of known nuclides, colored by decay mode, half-life, energies, mass excess, spin, year discovered, and abundance, with a detail view and decay chain for each one.
• A print constructor that composes a printable periodic table, exportable as SVG or PNG.
• Unit preferences for temperature, energy, distance, and abundance.
• Light, dark, and system themes.
  • Filled, empty, framed, tinted, and card element cell styles.
• Full English and Ukrainian translations.
• Installable as a progressive web app.
• A feedback form for reporting bugs and suggesting features.
