Local-first
Your data starts on your devices. Cloud sync is optional and exists to connect your own Mac and iPhone, not to turn Arca into a social platform or analytics product. If you ever stop using Arca, your data should still feel like yours.
Mac + iPhone, one loop
The iPhone companion is for fast capture: tick a life practice, move a task, start a focus session, or save health readings from screenshots. The Mac is for deep work, planning, dashboards, and longer coaching conversations.
Focus + planning
Arca gives you a focused daily work surface: practices at the top, a current task, ambient focus music, a timer, and a planning pipeline that keeps Today, Next Up, and Backlog in sync across devices.
Health · Wealth · Wisdom
The reflective rooms pair data with coaching. Health tracks recovery, sleep, body composition, and training. Wealth tracks net worth, cash flow, accounts, and spending. Wisdom tracks practices, reading, reflection, and the parts of life that make the rest worth doing.
AI on your terms
AI is a coach and collaborator, not the owner of the system. Use local Ollama when privacy matters, or connect an API provider when you want more power. Coaches can help think through plans, explain trends, and act inside the app when you ask them to.
Designed to be lived in
Warm parchment surfaces, deep navy ink, bronze accents, and quiet sound cues. Arca is meant to feel less like another SaaS dashboard and more like a well-worn notebook, a focus room, and a private vault for the work of building a life.
What it is not
Not a team-collaboration tool. Not a social network. Not a productivity slot machine. Arca is deliberately scoped to one person: the work in front of you, the practices that sustain you, and the longer arc you are trying to build.
