Do you ever: Open your social app, type a long rant, then delete it all Say “I’m fine” when you’re anything but fine Want to keep a journal, but can’t stick to a perfect daily habit Wonder, “Will this still matter to me in a year?” If that sounds like you, Time Courier is for you. What is Time Courier? Time Courier is a gentle journaling and mood app where you write letters to your future self. Capture how you really feel today, choose a day in the future, and let time deliver your words back to you. It’s not about productivity, streaks, or perfect pages. It’s about having a safe place to say, “This is how it really feels right now.” How you can use Time Courier • When you can’t post the truth online Instead of forcing a funny story or a filtered update, write honestly to future you. No audience. No performance. Just you on the page. • Choose a delivery date and let it go Send a letter to yourself 3 months from now, 1 year from now, or after a big turning point. On that day, you’ll get a notification: “A letter from your past self has arrived.” • Capture feelings, not perfect sentences You don’t need to write beautifully. One line is enough: “I’m exhausted.” “I’m scared.” “I’m proud.” Future you will understand exactly what you meant. • See how far you’ve quietly come As letters unlock, they become a private emotional timeline. You’ll see the nights you thought you’d never get through— and the fact that you did. • A private, judgment-free space No likes. No comments. No followers. Just a quiet little inbox where every message is from someone who truly gets you: you. Time Courier is for you if… You feel drained from always acting “okay” around others You’re in a season of change: breakup, new job, moving, studying, parenting You want to know what future you will think of today’s worries You want gentle proof that you really did your best during the hard parts Send today’s feelings forward. Let your future self open the letter and whisper back: “You were braver than you knew.” Time Courier – a mailbox between you and your future self.

Every Sunday, precog draws an AI portrait of who you become. A behavior-driven future self at 1, 5, and 10 years out, built from the week you just lived. Pure ritual, one minute a day. THE WEEKLY FUTURE-SELF RITUAL You upload one baseline photo. Through the week you log sleep, exercise, and water, a minute at a time. Every Sunday at 7 PM the portrait lands in your home screen. Resolution starts low and sharpens with every log; gaps blur the future. BEHAVIOR-DRIVEN AI PORTRAIT Three futures, side by side: PREDICTION - where this week is taking you WORST - if every habit slipped BEST - if you doubled down The triptych moves week by week. Watch your prediction drift toward the pole you're choosing. 1, 5, AND 10-YEAR HORIZONS Pro members see the same triptych at three time horizons. The same week, projected one year, five years, ten years out. Habit changes that look invisible at 1 year compound visibly at 10. BUILD HABITS THAT CHANGE YOUR FACE In 2011, Stanford research by Dr. Hal Hershfield showed people who saw an aged version of themselves saved twice as much for retirement. precog brings that mirror into your week. Not "someday you", next- Sunday you. The portrait is not a forecast. It's a compass: three poles between which the next decade of your face is being decided. FREE HABIT TRACKER + WEEKLY REVEAL Two free Sundays let you see your prediction and your envelope. After that, the future-portrait surface is Pro-only, but habit tracking keeps working without a subscription. Sleep, exercise, hydration logs remain yours. Pro adds: - Weekly triptych at 1Y, 5Y, and 10Y - Higher-resolution portraits across every horizon - Past-week deep dives - sleep, exercise, hydration broken down - Future revisions as your habits change Plans: - Future Self Monthly - $9.99 / month - cancel anytime - Future Self Annual - $79.99 / year - 33% off monthly - Lifetime Future Portrait - $199.99 once - keeps Pro forever YOUR PHOTO STAYS YOURS The baseline image is uploaded once and never used outside your weekly portrait. With your explicit in-app consent, your selfie and a numeric summary of the week's logs travel briefly to Google's Gemini API to render the portrait - described in detail in the Privacy Policy. You can revoke AI portrait service consent anytime in Settings. We do not sell, train on, or share user photos. No ads, no third-party analytics SDKs. THE WEEKLY CHECK-IN precog is one ritual repeated. Sunday evenings, you sit with the portrait. Most weeks the prediction barely shifts. Some weeks it moves markedly - toward the BEST, or toward the WORST. That movement is the point. The future you're heading into is being decided in the week you just lived. Built for a minute a day and a Sunday viewing, not a tracking grind. This app uses generative AI (Google Gemini 3 Pro Image) to render weekly future-self portraits, only after you grant in-app consent. Generated images are predictions based on your logged habits, not photographs and not medical, dermatological, or clinical advice.
