Self-Observation Method Five small practices that decide how today's you should move. Observe → Select → Act → Notice → Restore LifeOS is the best implementation of this method. You could practice it on paper. But for connecting sleep, activity, tasks, focus, and reflection into one place, LifeOS is the most natural fit. The more you continue, the more the data starts to return "your strengths and habits." Morning deep worker. Monday starter. The way your focus drops on the third session. LifeOS gives you back the final fruit of observation. "I feel off today." But you don't know why. Tasks pile up. Some days motivation just isn't there. But without knowing the cause, you repeat the same cycle. LifeOS - Self Observatory turns that vague feeling into a number. Your sleep, activity, and focus data become a daily energy score from 0 to 100. Tasks are suggested with reasons matched to your condition. The more you use it, the more your winning patterns emerge. A behavioral insight OS that tells you the best way to move through your day. Your companion for upgrading not just work, but life itself. Your Strengths + Your Observations (new in v2.5) After 14+ days of focus data, your strength type emerges — morning deep worker, evening sprinter, steady type, monday starter, evolving. Habit observations are delivered as findings, not judgments. Strengths needing more data are previewed as "unlocking in N days." Today's Power Your daily energy, scored from sleep, activity, and calendar data. Know at a glance whether today is a day to push hard or take it easy. AI generates personalized advice that changes every day. Today's 3 Tasks recommended with reasons matched to your energy. Switch by day with the date calendar. Toggle between "To Do" and "Today" modes. Tasks abandoned 30+ days get one-tap triage. Type "tomorrow 6pm" or "every Monday" — AI parses dates and recurrence automatically. Your Day Guide 3 tips based on your patterns, displayed every day. Auto-adapts to Power state, time of day, meeting load, and sleep. Insights "On 7+ hour sleep nights, your focus is 42% longer." Sleep vs focus, steps vs task completion, auto-correlated. The more you use it, the more your own patterns emerge. AI Monthly Review (Pro) At the start of each month, AI analyzes your previous month — winning patterns, trends, and next-month suggestions. Reset Protocol NOT (what to avoid), GO (where you're heading), DO (today's actions). A guided reflection to regain direction. Results stay on your dashboard at all times. Pomodoro Timer Every focus session feeds your Insights. Control from Live Activity, Dynamic Island, or Apple Watch. Apple Watch + Complications Power score displayed on your watch face. Know today's state with a glance at your wrist. Weather + Power Detects approaching low pressure and factors it into your Power score. Now you know why you feel off. Life Goals Your bucket list, visualized. Track long-term goal progress. Complete Privacy All data processed on-device only. Nothing sent to external servers. Cross-Device Sync Seamlessly sync across iPhone, Mac, and Apple Watch via iCloud. No re-onboarding when you add a new device.
