This website does not try to be a visually-appealing work of art — it simply presents software which has been hand‑crafted by the developer for functionality and usefulness or intrinsic interest. These programs run with all versions of Windows (including Win10), and on Macs with an emulator. They are all free to download (as trial versions). Click on a program title (e.g., Hermetic Word Frequency Counter) for information about pricing, what it is for, how to use it, etc. Or click on a thumbnail image for full‑size (then click the back arrow in your browser to return to this page).
