SOPHI0: Philosophy Zero

Slow down and think clearly. A daily philosophy practice with readings to grow, space to write, and on-device AI that reflects on your library. Private by design.

Sophi0 is a daily philosophy practice—a quiet place to read, reflect, and write your way toward a clearer mind. Most days move too fast for thinking. Sophi0 slows things down. Each day gives you a small, deliberate step: a short reading, a question worth sitting with, and space to write what you actually think. Over time, those steps add up to a habit of thinking clearly. Rooted in the Stoic and classical traditions—but written for now—Sophi0 isn't about memorizing philosophers. It's about practicing what they were actually after: seeing your own mind more honestly, loosening the grip of anxious thinking, and returning to what matters. SOPHI0 THINKS WITH YOU On iPhones and iPads with Apple Intelligence, the eye opens: • Synthesis — choose any of your reading batches and your own writing, and Sophi0 composes an original philosophical reflection from them. Your library becomes a knowledge base; the output is yours to keep. • Daily Spark — each morning, a short reflection distilled from your own bits, in the tone you choose: stoic, uplifting, challenging, or calm. • Philosophy Profile — tap your name and see where your thinking leans across ethics, epistemology, metaphysics and more, the themes you keep returning to, and a philosopher worth reading next. • Explain — any passage, unpacked in a few sentences using that author's complete body of work. Everything generates on your device with Apple's on-device intelligence. Nothing you read or write ever leaves your phone. No Apple Intelligence? The full practice works exactly the same—these features simply wait. WHAT'S INSIDE • Daily cycles — a steady rhythm of short readings and reflective prompts, one bit at a time. • Room to write — capture your thoughts privately, 128 words at a time; every 32 bits becomes a batch you name and keep. • Truth ⊤ and Fallacy ⊥ — pass judgment on what you read, the way logicians always have. Your verdicts shape your Profile. • A foundation to begin — an opening series and a library of readings are yours from day one, free. • Ports — anchor what you read to real action. • Home-screen widgets — the Daily Spark or a rotating bit from any batch, plus your Moments Bank at a glance. • Full iPad support, with adjustable text size and Dynamic Type — a wider, more readable page for a reading, writing life. A LIBRARY THAT GROWS Sophi0 reads packs—self-contained reading batches you import. New philosopher series and theory arcs arrive as packs and join your practice, dripping one bit a day on your own schedule. Free packs are available to everyone; import one and it becomes part of your archive to read, judge, and synthesize like anything else. PRIVATE BY DESIGN Everything you write stays on your device. No account. No login. No tracking, no ads, nothing sent to a server—including the AI, which runs entirely on-device. Export your work to a file anytime and keep your own backup. SIMPLE, HONEST PRICING Sophi0 is free. Reading is never sold inside the app—it arrives as packs you import. The only in-app purchases are for your own writing: unlock unlimited writing beyond the free limit, or add tokens to advance your daily cycles faster. One-time purchases. No subscriptions.
