📝 About this app
<b>
UPDATE: As I have not been maintaining this app for years, I've decided to make it open source under the GNU General Public License v3.0. If someone is interesting to become a maintainer or a contributor, send me an email.
The full source code is now available on GitLab: https://gitlab.com/razorscript/fxcalc
The app was built with Adobe AIR SDK and the Feathers UI library. Both are now quite outdated. It would probably take not too much effort to update the app to use a recent version of AIR SDK from HARMAN (the current maintainer of AIR).
