Here are some apps I have developed in the past and which are noticable.

JPEXS Free Flash Decompiler

FFDec is a free, open-source tool designed for analyzing, decompiling, and editing Adobe Flash (SWF) files. It allows users to view and modify ActionScript, graphics, sounds, and other Flash assets, export them to common formats, and recompile them back into modified SWF files. The program is cross-platform and widely used for studying, modifying, or recovering legacy Flash projects.

Matice 2

Matice 2 is a Czech application designed for performing calculations with matrices in a simple multiple-document (MDI) interface. It allows users to work with multiple matrices at once and perform standard operations such as transposition, addition, subtraction, multiplication, matrix inversion, Gaussian elimination, computation of determinants and rank, and more. The application features an intuitive user interface where matrices can be created, named, and edited, saved in MT2 or CSV formats, and exported to Excel. It also supports working with complex numbers and exact calculations using fractions.
