A fast and fully-offline desktop app for browsing isotope and nuclear structure data in the Chart of Nuclides / Segrè chart format, using nuclear structure data from ENSDF, masses from AME2020, and isotopic abundance data from NIST. A full list of features is here.
Prebuilt binaries are available for desktop Linux (via Flatpak) and Windows 10+. The latest release and installation instructions are here.
Prebuilt binaries are not available for MacOS (I don't have a Mac to build and test with), but others have confirmed that the application can be manually built for MacOS using the instructions here.
See the user manual for documentation.
Detailed build instructions are here.
