16 native apps from a one-person workshop. They work on your own files, on your own Mac, and they ask before they change anything.
Every day gets its own folder.
Drag in whatever arrived today: photos, clips, documents. They're copied into a dated folder tree where you sort, label, review and write the day's notes, then export a report.
macOS 15 or later · Apple silicon
A viewer for a folder, not a library.
Opens a folder (your Downloads unless you pick another) and plays the pictures, video, audio and documents in it. Convert, trim, crop, watermark, clean up voices and strip metadata without moving a file.
macOS 15 or later · Apple silicon
Find duplicate photos and videos.
Byte-exact and visually similar matching, for stills and video. Live Photos stay paired, and you see every match before anything moves.
macOS 14 or later · Apple silicon
Copies you can prove.
One source to many disks or shares, read once and verified at a level that says exactly what it proves. Every job leaves an evidence folder you can attach to a ticket.
macOS 14 or later · Apple silicon
Flatten a folder tree, with undo.
Brings every file in a nested tree up to one level. It shows the plan first, never overwrites by accident, checks its own work, and puts it all back if you change your mind. Includes the pflat command-line tool.
macOS 14 or later · Apple silicon
Open every archive, old and new.
Zip, 7z, RAR, tar and friends, plus classic Mac formats like StuffIt. Extraction guards against archive bombs, and the parc command-line tool shares the same engine.
macOS 13 or later · Apple silicon
See what's filling your disk.
Scan any folder and see where the space went as a sortable tree, then clean up the large and the forgotten.
macOS 10.15 or later · Windows
Markdown, written and read.
A fast editor that flips between a rendered document and highlighted source, with Mermaid diagrams and LaTeX math. It also previews .md files right in Finder's Quick Look.
macOS 14 or later · Apple silicon
Read and edit PDFs.
Annotate, fill forms, reorder pages, sign and password-protect PDFs. Local-first, with no telemetry and no account.
macOS 10.15 or later
A journal that never leaves your Mac.
Entries, photos and audio live in one encrypted database on your Mac. Lock individual journals in their own vaults. No account, and nothing you write goes anywhere.
macOS 14 or later · Apple silicon
Mind maps that fan out from one idea.
Sketch on an infinite canvas and watch colour-coded branches grow from a central topic. Export as an image, a PDF, or a Mermaid diagram.
macOS 10.15 or later · Apple silicon · Windows
Make your Mac look the way you want.
Pick a theme and the colours, wallpaper, folder icons, Dock and sounds change together, or change one setting at a time with a plain-English note on what it does.
macOS 26 or later · Apple silicon
An X-ray of your Mac.
A deep, on-demand scan of logs, settings and system internals. It puts anything wrong at the top and explains what every item is.
macOS 14 or later · Apple silicon · Full Disk Access
Mail rules across every account.
Rules that read like sentences, applied to new and existing mail in iCloud, Gmail and Proton over IMAP. It remembers every change it makes, so anything can be undone.
macOS 14 or later · Apple silicon
A native IRC client.
Built in Swift on Apple's own networking stack, with TLS, SASL sign-in and a tidy sidebar of servers and channels.
macOS 14 or later · Apple silicon
Classic Mac IRC, rebuilt.
A nostalgic recreation of the Mac OS 9 era client, in Platinum chrome, with today's comforts underneath.
macOS 14 or later · Apple silicon
Downloads come straight from GitHub. The Mac apps that say Apple silicon need an M-series Mac. On first launch macOS may ask you to confirm you want to open an app you downloaded; that's expected.
