Apps

Track Slash is an open-source issue tracker for teams that need speed, clarity, and control without vendor lock-in. Visit trackslash.com for the public website.

Vault is an open-source iPhone, iPad and Mac app for the secrets you can't afford to lose: seed phrases, private keys and private notes, and your 2FA codes too. It's fully offline, and built for the moment someone forces you to unlock it.

GPS is an iPhone and iPad app that shows live readouts from your phone's GPS receiver: position, speed, altitude and accuracy, as a plain list, as fullscreen instruments, and as a dashboard you arrange yourself.

Limits is an iPhone and iPad app that shows how much of your AI subscriptions you have left, and when each limit resets: Claude, Codex, Cursor, Gemini CLI, GitHub Copilot, Grok, Kimi Code, Z.ai and MiniMax, in one place and in widgets.

Split Thing keeps track of shared costs for trips, households and anything else a group pays for together: who paid, who it was for, in any currency, and who owes whom. Visit splitthing.com to start a group.
