From the catalog
Selected work
-
RSync Pro
Syncs folders the moment they change — real rsync driven from a Mac window, to a second disk or to your own server over SSH.
-
TabBar for Word & Excel
Native document tabs for Microsoft Word, Excel and PowerPoint on the Mac — switch between open documents with one click.
-
Snippet
A keyboard for the text you send over and over, on Mac and iOS — with templates that fill themselves from a message you select, and everything in sync across your devices.
-
Voynich
Encrypts your files and folders on the device, replacing each with an AES-256-GCM version under the same name. Its vault keeps passwords, recovery codes and private notes in one encrypted file you place yourself. No server, no account, and your recovery key opens everything on any computer.
-
PureWrite
A writing environment over a folder of Markdown files: start typing and the sidebar and table of contents fade away, leaving the document alone on screen. Folder-wide search, and every paragraph in its own direction.
Capabilities
