Good for no reason.

Floof Logic is an independent software lab. We make unusually capable software. Mardo is the one we want everybody to use. The rest is proof that we're serious when we say “unusually capable.”

Mardo

The native Markdown viewer for Mac.

Select a Markdown file in Finder, press Space, and it is already beautiful. A 50 GiB file opens in 124 ms, and every jump into it draws in under 13 ms. When Claude Code or Codex edits the file you are reading, Mardo follows the change live, in place. Free to view, forever. Mardo Pro adds editing for US $29.99, once.

The rest of the lab

Things we've built because apparently we can't help ourselves.

Wishware: your phone can make its own software.

Wishware

Your phone can make its own software. Tell it what you want; the phone writes, builds, signs, installs, and runs the native app itself.

Blackwall: your phone is the build machine

The machinery underneath Wishware

Blackwall

The entire development machine underneath it runs on the phone. Real Linux, real PTYs, real AI CLIs, real Android toolchains, all on-device.

Barkimedes

We were putting local generative AI inside an iPhone in 2023. Before Floof Logic had a strategy, we put a brain in a dog.
