Run your program. Coach theirs.
A strength training app that works in the basement gym with chalk on your hands, with or without a signal. Start a proven novice progression in minutes, or run your own plan. Log a full workout from the watch alone. Coaches enroll trainees and propose adjustments they approve. Waitlist open; founding members get a three-month trial at launch.
barbear.fit →A quality control plane for coding agents. Independent branches of the task graph run in parallel worktrees. The agent that wrote the code never reviews it, and deterministic gates decide what ships.

I'm a Swedish software engineer based in Metro Manila. My software belongs in daily life: the words you speak, the miles you drive, the training you log, the calendar you keep. And what it touches stays yours: transcribed on your own Mac, logged on your own watch, computed from the sun and the moon rather than fetched from a feed.
I care about the unglamorous parts: the audit trail, the export format, the interface a script can call. And I don't ship half-measures: a tool should be polished, earn trust through quiet correctness, and outlive its first release.
