If you move between work, study, rest, and everyday life but cannot clearly say where your time went, knoself connects planning, time tracking, time logs, and review in one personal app. knoself includes: 【Quick Start】Start from the Action Button, Home Screen widgets, Lock Screen, Apple Watch, Today's Reminders widget, an in-app task, or a system calendar event. Add text, tags, and photos while the timer runs, or adjust its start time. 【Time Cards】Every period of real effort becomes a time card. Along with time spent, keep notes, ideas, mood, context, and takeaways so you can understand the moment later. 【Journal Timeline】Pick a journal-style timeline or a continuous stream. Days get clear dividers, so timers, journals, and reflections read in order; an All-day journal entry captures the day without adding focused time. 【Images and Clipboard to Tasks】Share an image, text, or link from Photos or another app, or explicitly read supported clipboard content. On-device text recognition extracts useful details; confirm the title, date, time, and destination before creating a task or calendar event. 【Tasks and Calendar】Create tasks with dates, times, repeats, alerts, photos, and tags. View the week as an agenda or board. With Calendar access, view events and start timing from one, then write completed records to your calendar when you choose. 【Multi-dimensional Tags】Use # tags for projects, contexts, state, energy, or mood, then review your time from different angles. 【Health Data】Bring mindfulness, sleep, and workout periods from Apple Health together with manual time records. 【See That Moment】Open a time card to find nearby photos and videos and view Screen Time context. These details are read only after you open this view. They are not written to the record or uploaded. 【Daily Highlights】Revisit selected time cards from your past each day. Add a fresh reflection without replacing the original, and exclude tags you do not want to see again. 【Review and Reflection】Use time breakdowns, 24-hour distribution, yearly heatmaps, tags, and task statistics to see what takes your time and when you enter a focused, productive state. Open the cards behind each chart, or share selected records with AI tools for review using Three Good Things, KPT, or the 4P model. On Mac, a local MCP service lets AI assistants query and control timers with your confirmation. 【Multi-device and Local-first】Use knoself on iPhone, iPad, Mac, and Apple Watch. Records stay on the device by default, with optional iCloud Sync. Sharing and export happen only when you choose. What knoself is good for - Record real effort across work, study, reading, exercise, quick tasks, and everyday life. - Organize to-do lists, repeating items, and calendar plans, including plans captured from images, text, or links. - Add context with time logs, notes, journals, thoughts, mood, photos, and takeaways. - Review your rhythm through tags, charts, time distribution, photo context, and rest state. - Open related time cards or share selected content with AI tools for deeper reflection. What knoself is not for knoself is not designed for team timesheets, client billing, or full calendar management. It does not monitor every app or website in the background. Screen Time context appears only after you deliberately open See That Moment, inside the system-provided read-only report. Privacy and Data - Records are stored locally by default - Image text recognition runs on the device - iCloud Sync is optional - Sharing and export are initiated by you - No account is required to start recording A time tracker gives you more than a list of minutes. It gives you real evidence of your attention, mood, habits, and daily rhythm. Start recording this minute.
