Apps I’ve shipped.
Things I’ve built and released — made with care, mindful of your privacy, and designed to stay out of your way.
Mantella
Point Mantella at a folder of PDFs and it becomes your library — crisp native-quality rendering, instant search, and it always remembers exactly where you left off.
Perch
A tiny macOS menu-bar utility that resizes, centers, and focuses your frontmost window with a single global shortcut — everything else politely steps out of the way.
Todo Tide
Make color-coded lists, check things off, and keep a list on your Home Screen. No account, no ads — your tasks stay on your device.
