Delta.|洲 is a local-first system for personal records and reflection. It brings scattered time, ideas, focus, plans, and everyday notes into one thread, so today’s actions can stay connected to what you have already learned. Today See what is ahead, open the four fastest capture actions, and review your daily flow and recent rhythm from one place. Do Drop an idea or speak a fragment that saves automatically after transcription. You can also record the time that just passed or start a focus session. Ideas can include text, links, images, and PDFs, then settle into topics over time. Plan Manage tasks, goals, classes, events, and calendar entries on one decision state instead of moving between separate tools. Review Compare action with plan, then review daily deposits, communication, people, health, and everyday evidence to see what should continue or change. Improve Carry open threads from review into the next plan, then refine stances, thinking, and controllable memories so insight returns to action. Ask Delta Ask questions using the records, schedule, and controllable memories you choose to provide. Answers keep their supporting context visible for review. Data control No account is required for the main local experience. Records are stored on this iPhone by default. You can import, export, restore a backup, or opt in to cross-device sync. Delta has no advertising and does not track you across apps. Voice transcription and some other online features require an account connection and network access. Class, event, and Matrix status depend on the availability of their corresponding services.
