Independent software studio
Codonic builds native tools for creative work and travel on macOS, iPadOS, iOS, Windows and Android. Few products, each taken further than the category usually bothers to go — and each written for the way the job is actually done.
Practical guides
Detailed methods for travel spending, group costs, handwriting and document work.
A practical system for solo and group trips: capture every payment quickly, keep currency conversions honest and settle shared costs cleanly.

Six products: a drawing and handwriting surface for a computer, a travel ledger built for solo and group trips, a private command center for AI agents and an always-on Mac, a browser extension that makes the speaker in a recorded lecture audible again, an open-source tool that continues a Claude Code or Codex session on another of your machines or in the other agent, and a self-hosted queue that spreads batch jobs across the computers you own.
Use your iPad or Android tablet as a pressure-sensitive pen tablet for your Mac or Windows PC
Pad turns the iPad or Android tablet you already own into a pen tablet for your Mac or Windows PC. It streams the computer’s screen to the tablet and sends the stylus or touch input back, so you can draw with pressure in desktop art apps, handwrite notes or sign a document without transferring the file.
Control AI agents and Mac apps from anywhere on your own network
MyCNC turns an iPad or iPhone into a command center for the AI agents, terminals, localhost services and native apps running on an always-on Mac. A separate MyCNC Host app on the Mac provides direct screen streaming and input over your LAN or tailnet.
Travel expenses in any currency, split with friends, kept as a journal
A trip ledger that keeps up with the trip. Log a purchase in seconds in the currency you paid, keep ATM cash in cash pockets, split costs with friends and settle up in fewer payments. Then every day becomes a chapter in the Journey Ledger, with the photos and places beside the numbers.
Hear every lecture from the front row
Front Row makes the speaker’s voice in web videos clear and comfortable. It was built for university lecture recordings with bad sound, and it works on any site with video. Noise reduction, clarity, a leveler and volume boost all run live inside your browser.
Continue any coding-agent session, on any machine, in any agent
hopsesh brings a Claude Code or Codex session from any of your machines to the one you are on, or continues it in the other agent, with its repository, worktree and code. A loss report shows what carries over before anything is written, and undo works on every machine it touched.
Spread batch jobs across the computers you already own
Oarbank turns the Macs, Linux machines and Windows PCs you already own into one fleet for batch work. A coordinator hands each job to a node with room for it, host protection keeps room for each computer’s own work, and every job runs in the operating system’s own sandbox.
Small instruments for improvising musicians, built around random elements. Alea is Latin for dice, as in aleatoric music.
Random notes from any scale, slowly morphing into another
An improvising human player, and a machine that randomly shifts from a diatonic scale to complete dodecaphony over time. Pick a preset or set up your own two scales, morph between them, or hit AUTO-SWEEP and let Scale Shifter travel on its own.
Random chords to improvise over
Generate a short random chord progression, loop it, and improvise over it with your instrument. A progression you did not choose forces your ear and your hands out of familiar shapes.
Approach
These are working rules, not slogans. They decide what gets built and what gets cut.
Swift and SwiftUI on Apple platforms, native toolkits elsewhere. Hardware video encoders, the real pencil APIs, the platform’s own frameworks — the things that make an app feel like it belongs on the machine.
Every app starts from the one thing the category keeps getting wrong, and refuses to ship until that part is right. The rest of the feature list follows from it.
Latency is a feature. We budget it, measure it and show it, because a tool you have to wait for is a tool you stop reaching for.
A small studio, a short list of products, and a reply from someone who can actually open the file you are having trouble with.
Questions, bug reports and feature requests all go to a person, not a ticket queue.
