• We've improved the UI for the Challenge Builder – use it today to create your own customised chemistry challenges!

The catalyst to your chemistry study: • We've added 3 new tutorials, Introduction to Isotopes, Electronegativity and Atomic Number. • We've added 2 new themes! You'll love Chromatic Chemistry and Element Eclipse. • We've improved the end of quiz dialog. • We've added periodic trend quizzes for ionisation energy, atomic radii, metaliic character in addition to electronegativity! • Bug fixes and performance improvements

We've updated Atomdash to include 2 new tutorials! • Introduction to the Periodic Table, for a basic introduction to the periodic table for first time chemistry learners • Atomic Number, an introduction to atomic numbers and how they relate to the periodic table of the elements

• Fixed a bug that would crash the app on Mac Catalyst • The discovery timeline feature is back

• Themes! • Added additional data • Bug fixes

• We've added the ability to quiz yourself on the periodic trends, starting with increasing electronegativity! • There is a new 'Discovery Timeline' that provides a beautiful visual teaching aid for the history of chemical discovery • We've added a Bohr model for each element to the element detail popover! • We've also added a fullscreen 3D interactive Bohr model • We've made additional improvements to the UI

• We fixed a bug that meant the number of questions selected in the Quiz Builder would be ignored and always set to 10 • We also fixed a bug where the 'Quiz Complete' screen would be skipped after successfully completing a quiz

• We redesigned the 'Quiz Select' menu to make it easier to browse the available quizzes • The 'Get Hint' button is now hidden for a few moments when a new question is presented in a quiz

• We introduced a new Quiz Builder feature so you can create your own custom quizzes • We've slightly changed the format of our pre-built quizzes which can now be limited to just certain sections of the periodic table

• Added the ability to configure the style of each tile in the table to suit your preference • Added the ability to toggle whether or not atomic number is shown on the table to allow you to prioritise more space or more information • Added UI and quiz sounds as well as a global mute button • When tapping into the detail view for an element, all other elements will now be muted • There have been some minor improvements made to the UI
