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.

Eidra is a quiet memory for the people in your life. Tap once. Speak. Or type a few words. The AI listens, extracts the names, places, interests, and follow-ups, and holds them for you. Months later, when you bump into someone and your mind goes blank, you ask Eidra. The answer is already there. WHO IT'S FOR The friend you saw at a dinner party last spring (whose new partner's name you keep almost remembering). The neighbor you've waved at for two years and never quite caught the name of. The mentor you met at a conference whose advice you can never relocate when you need it. Your kid's teacher, your cousin's husband, the barista who knows your order, the new colleague who mentioned a hobby you wanted to ask about. The dating app match whose stories you want to hold onto. The mom of your daughter's classmate. Anyone you've ever wanted to remember a little better. FOR WORK, TOO Sales reps building rapport with prospects across long deal cycles. Founders tracking the people they meet at every dinner, conference, and intro coffee. Recruiters keeping context on candidates and clients. Investors holding onto the threads of every founder pitch. Anyone whose job depends on remembering people well. Eidra is a personal CRM that does not feel like a CRM. The same fast capture, the same effortless recall, just as useful for the prospect you met last quarter as the friend you saw last weekend. WHAT MAKES IT FEEL DIFFERENT Most apps make you do the work of organizing. Eidra does it the moment you speak. You say, "had drinks with Leslie, she just got back from Lisbon and is starting sourdough lessons." Eidra extracts Leslie, the trip, the new interest, and the date. It writes a one-line entry into her timeline. It updates her structured profile so the next time you ask, "what's Leslie been up to," it remembers all of it. Her card even grows with her: as you capture more, Eidra reconciles the details over time, remembers the family and pets around her, and links her to the people she's connected to. It is not a note-taking app. It is not a journal. It is a memory aid that makes the small details feel effortless to keep. WHAT YOU CAN ASK Once you've captured something, you can ask Eidra anything about anyone: • When did I last see Marcus? • What was the name of Sarah's daughter? • Who did I meet last month interested in startups? • What was that book Olivia mentioned? Eidra answers in your own words, the moment you need it. ALSO INSIDE • Important dates & reminders: a calendar of every birthday, anniversary, and follow-up, with an optional heads-up two days before so you never miss one • Connections: link people together and remember how they relate • Family & pets: Eidra quietly remembers the people (and pets) around the people you know • Briefings: a 30-second AI recap before you see someone again • Custom prompts: ask anything specific ("what should I bring up with Eli?") • Hidden contacts: lock private notes behind Face ID • Voice or text capture, your choice every time SUBSCRIPTION TIERS Eidra is free to start, with limits. Unlock more with a 7-day free trial: • Eidra Casual ($2.99/month): unlimited contacts, 20 captures/day, 5 briefings/day, custom prompt briefings • Eidra Business ($4.99/month): unlimited contacts, 40 captures/day, 10 briefings/day, custom prompt briefings, priority support Subscriptions auto-renew monthly until canceled. Manage or cancel anytime in iOS Settings, Apple ID, Subscriptions. PRIVACY Your notes stay in your account. Audio is deleted right after transcription. AI runs server-side and never trains on your data. Read the full policy at eidra-site.vercel.app/privacy.
