The Low Dopamine Path
Read full descriptionHide full description
Most apps want your attention. This one wants to give it back. The Low Dopamine Path is a 90-day field notebook that pulls you out of the scroll and back into the real world โ one tiny quest at a time. No feed. No likes. No streaks shaming you. No notifications begging for your attention. Just one real-world action a day, and a paper-ink notebook that fills up as you go. โโ WHAT YOU GET โข 90 daily quests, hand-curated across 4 chapters โข A custom camera to capture proof โ your moment, not a post โข A field notebook that quietly fills with stamps, photos, and ink โข Home screen widgets that nudge without nagging โข Optional shareable cards (Instagram Stories) when you want to โข Designed for Reduce Motion, system sounds, and your nervous system โโ HOW IT WORKS 1. Open the app. See today's quest. 2. Do it. In the real world. With your eyes up. 3. Snap a photo as proof. It stays in your notebook. 4. Close the app. Live your day. That's the whole loop. No infinite scroll. No "for you" page. No dark patterns. โโ THE FOUR CHAPTERS Chapter 1 โ Notice. Wake up to what's around you. Chapter 2 โ Move. Get your body involved again. Chapter 3 โ Connect. Real conversations, real people. Chapter 4 โ Build. Make something that lasts past the day. 90 quests. 90 days. One path back to attention. โโ WHO IT'S FOR โข Anyone who unlocks their phone and forgets why โข Anyone who finished a season but can't remember the plot โข Anyone who wants their attention back without a 10-day silent retreat โโ DESIGNED ON PURPOSE Paper-ink aesthetic. DM Serif Text and IBM Plex Mono. No dopamine-bait colors. No engagement loops. The app is intentionally a little boring โ so your life can be a little more interesting. โโ PRIVACY Your photos stay on your device. We don't have a feed. We don't have a social graph. We don't sell anything to advertisers. There's nothing to sell. โโ Subscription auto-renews unless cancelled at least 24h before the period ends. Manage in App Store settings. Less screen. More life.

System Zero
Read full descriptionHide full description
System Zero is not another habit tracker. It's the operating system that runs your life when you can't. You already know what's wrong. You're heavier than you should be. You haven't seen a friend in a month. Your salary hasn't moved in three years. You've tried streak apps, Notion templates, YouTube routines. They all turned into another tab you stopped opening. System Zero takes a different approach. It diagnoses where you actually are. It tells you where you should be. Then it runs the Protocol โ a multi-week program with daily briefings, prescribed actions, and hard verification โ until you get there. โ THE DAILY LOOP โ ยท Morning Briefing. 90 seconds. What today asks of you, and why. ยท Prescribed Action. The exact move for today, with stakes if missed. ยท Verification. Photo, GPS, or health-data proof. Not a button tap. ยท Evening Debrief. 30 seconds. Reflection the System remembers. โ FIVE DOMAINS, ONE OPERATING SYSTEM โ BODY โ your fitness, weight, sleep. A 12-week program with progressive overload, real workout templates, and verification through Apple Health. BONDS โ the relationships you've let fade. A contact-aware program that schedules check-ins and in-person time across the people who matter. CRAFT โ your career trajectory. From a market-rate audit of where you are now to outreach, applications, skill milestones, and the negotiation. WEALTH โ your money. Cash flow audit, debt mapping, emergency fund, savings rate, first investment account. COURTSHIP โ your dating life. Coaching, not matchmaking. Profile audit, photo guidance, conversation review, real date planning. โ STATUS, NOT STREAKS โ Every Sunday, the System pulls together your week. What you verified. What slipped. The pattern you didn't notice. Every month, a Life Report compares you to your baseline. "Down 4 pounds. Seven verified social actions. Craft track: still no movement. Why?" Every quarter, a full Recalibration. New Diagnostic. New Status Report. Side-by-side with the original. You see the arc. โ WHY IT WORKS โ Habit trackers measure consistency. System Zero measures change. Productivity apps give you tools. System Zero gives you a curriculum. Coaching apps are expensive. System Zero is coffee-money and runs every day. Self-improvement gurus motivate. System Zero operates. โ WHAT THIS APP IS NOT โ Not a habit tracker. Not a fitness app. Not a dating app. Not therapy. Not a manifestation or vibes app. If you want streak rewards and a confetti animation, this is the wrong product. โ ACCOUNTABILITY THAT'S REAL โ Self-reported actions get partial credit. Verified actions โ photo proof, GPS check-in, Apple Health data, banking confirmation โ get full credit. Phases don't advance until verified evidence clears the bar. You can't fake your way through. โ PRIVACY โ Your data is yours. No selling. No ad targeting. Verification photos are stored encrypted and visible only to you. Delete your account from settings any time โ all user records wiped within 30 days. โ PRICING โ Free to start with the Diagnostic and your first week. Pro subscription unlocks the full Protocol across all five domains, the System's memory layer, and the weekly Status reports. Monthly or yearly. Cancel from the App Store any time. โ GET STARTED โ Open the app. Run the 15-minute Diagnostic. Get your Status Report. Pick two Tracks. The System takes it from there. Not motivation. Operation.
