Apps

Updated Sep 23rd, 2026

I make software for writers. The long-term goal is a contraption I call the Gelehrtenmaschine, a scholar’s engine, and most of these apps are parts of it: utilities at the base that run all day, editors above them, and the note archive on top. I designed, built, and sell all of them myself; each name leads to the app’s own website. Case studies of these and of client work are in the portfolio; the full history is in my CV.

The Engine

Archive

The Archive 2018 · Mac

Plain text note-taking for the Zettelkasten Method. Search stays instant across ten thousand notes and more, themes and plug-ins are yours to change, and the notes remain files on your disk. Case study.

Editors

TableFlip 2016 · Mac

A visual editor for Markdown tables. Open the document next to your text editor, edit the table, save, and the file updates in place. Case study.

Infinite Canvas 2025 · Mac, iPhone, iPad

Drawing and whiteboarding. Zoom and pan without end, draw with Apple Pencil, export as SVG. Case study.

All day

WordCounter 2013 · Mac

Counts what you write, in every app, all day. The history shows when and where the writing gets done. Case study.

Move! 2016 · Mac

A break reminder. It makes you stand up, and a break only counts once you actually stop working. Case study.

Utilities

Calendar Paste 3 2012 · iPhone

Event templates for the iPhone calendar. Paste a shift or an irregular appointment into the day instead of typing it out again. Case study.

Open Invite 2026 · iPhone

Opens .ics invitations from Files, Mail, or Safari. Preview the event as a card, see what it clashes with, and add it to your calendar. Free, with a tip jar. Case study.
