Updates

Version 1.15.0 - November 28, 2025

New: Desktop App

Molequles now has a Desktop application which provides the option of running the app completely offline without an account (as well as an Online mode which works the same as the web app). The desktop app is available for Mac, Windows and Linux.

• Significant rewrite of data layer under the hood, increasing performance and stability
• Code libraries updated to latest versions

Bug fixes

• Search in the Materials page now re-indexes as changes are made to materials.
• Sync errors will no longer cause the loading screen to get stuck. Users can continue to work with changes persisted locally.

Version 1.8.2 - August 13, 2024

Bugfixes

• Fixed an issue where the app failed to load when there was a cyclical formula (i.e. a formula that referenced itself)
• Cyclical formulas are marked as errors in the "Show Inner Entries" view. It is recommended to remove/fix any cyclical references like this since it can cause weird calculations

Version 1.8.1 - August 10, 2024

New Features

• Notes: You can now create and manage notes from the new Notes page in the navbar
  • Notes use a rich text editor with support for headings, bulleted/numbered lists, bold/italic/strikethrough, links, and more

Minor Changes

• Deleting a formula entry now opens a confirmation modal, to prevent accidental deletion of entries
• Import Materials page now shows the correct field names for various fields
• Weight values are now rounded to the nearest 4 decimal places, mostly to keep things readable when scaling a formula

Version 1.5.0 - July 14, 2024

New Features

• Usage Graph: There is now a graph in the Usages area of the material editor, to help visualize how you use your materials and identify patterns
• Mark as Solvent: Materials can now be designated as Solvents by checking the "Mark as Solvent" checkbox in the material editor
  • This will result in more correct calculations for relative and absolute percentages for these materials, and will also group them when using "Group By" in the Formula editor
  • This is a non-destructive action, so all previous usages and dilutions of these materials are retained, in case you decide to un-mark a material

Version 1.4.7 - May 26, 2024

Minor Changes

• Multi-select in the Materials page is a bit more intuitive and now supports deleting the selected materials
• NOTE: Deleting materials is a very destructive action and will delete any usages of that material in formulas, which will result in a change in your formula percentages. Deletion cannot be undone, so use only if needed

• Ironically, the Export User Data action was broken in the Demo app. It's fixed now
• Materials Database tags are now clickable for quicker searching

Version 1.2.4 - January 20, 2024

Minor Changes

• Materials Database search algorithm has been improved to push more data-rich results to the top. This should simplify searching for something like "Sweet Orange," which previously returned some random unknown variant of orange EO. Now it returns "Sweet Orange Peel Oil" which has lots of data and is more likely to be what you're looking for
