Portfolio
One app at a time, each aimed at a problem specific enough to be worth solving properly.
iPhone & iPad · iOS 26+
The step between writing in Markdown and handing it over. Four formats, a contents page that really navigates, diagrams and equations drawn rather than dropped — and an unpublished manuscript that never leaves the phone.
iPhone & iPad · iOS 26+
A private AI meeting assistant, and a teleprompter for the meetings the rest of us are in. It follows the conversation, searches the documents you brought, and puts the next thing worth saying on screen. On the device, with no signal needed.
Garmin watch · Connect IQ 3.2+
The next train, bus or ferry from the stop you are standing at, in Sydney or anywhere in New South Wales, on your watch. Times are the timetable corrected with live data, so a late train shows as late. Choose a departure to see the stops ahead, and the watch buzzes before yours. It asks before it uses your location, and our server answers and does not keep it.
Finishing final touches
iPhone & iPad · iOS 26+
What the listing leaves out, for any address in New South Wales: the schools it is zoned for, the nearest station, recorded crime, flood and bushfire maps, rents and past sales, all from public data. Free, with no account. Searches are answered and not kept, and the homes you save never reach us.
Not announced yet
More is being built and it is not ready to talk about. When it is, it will turn up here rather than in your inbox — there is no mailing list, because there is nowhere to keep your address.
Building
What every app here has in common
Not decisions we revisit per app — constraints an idea has to survive before we build it. The model runs on your device; there is no account; nothing that could identify you is collected; and each app says exactly what, if anything, leaves the phone, in words that are literally true of that build.
Open source
Owl, for short: the tools we build with, free for anyone to use and change. They are developer tools, not apps, so the four rules above do not describe them; each one says plainly what it sends, and where.
Mac · macOS 14+
An MCP server for developers of Garmin watch apps who work with an AI coding agent. The agent builds the app, runs it in Garmin’s Connect IQ simulator, reads the screen and presses the buttons, so it checks its own work by looking. Part of the OwleryWorks Library, our open-source tools: for the Mac, it runs on your machine and sends what it sees only to your agent.
