Syncro - Remote Work Wellness

Syncro — the wellness companion for remote workers. Eye breaks, movement, and a live global community that keep you healthy when your office is everywhere.

Inspiration

The pandemic turned "the office" into "a laptop on the kitchen table." Millions of people suddenly worked 8–10 hour days with no commute, no walk to a meeting room, and no reason to stand up. The result is a quiet epidemic: screen fatigue, tech-neck, stiff backs, and the loneliness of working in an empty apartment.

The seed of Syncro is the 20-20-20 rule — the ophthalmologist's guideline that every 20 minutes you should look 20 feet away for 20 seconds. It's simple, evidence-based, and almost nobody actually does it. Over a workday of T T minutes, that's a surprisingly demanding schedule:

N

breaks

⌊ T 20 ⌋ N breaks ​ =⌊ 20 T ​ ⌋

For an 8-hour day, that's 24 reminders — which means a reminder app that isn't delightful, personal, and human will be muted in the first hour. That was the design bar we set for ourselves.

What it does

Syncro is a daily wellness companion for remote and desk workers, with five tabs covering the whole workday:

Home — a focus meter, hydration tracking, 20-20-20 eye-break timer with Meeting Mode, posture check-ins, mood logging, daily quests that adapt to your pain areas, and streak tracking. Move — a guided remote workout and "stealth stretches" you can do on camera without anyone noticing. Fuel — the 3pm energy-crisis snack menu and a 30-day brain-nutrition calendar. Connect — the heart of the product: a live global pulse of remote workers, real-time chat rooms matched to your workday phase, deep-work focus sessions, and a virtual office of active coworkers. Remote work's biggest deficit is not physical — it's social. Settings — work schedule, reminder personality (Ninja, Coach, Drill Sergeant), premium status, restore purchases, and account deletion. Syncro monetizes with RevenueCat: a free plan keeps the core habit loop (eye breaks, hydration, posture, 2 focus sessions a day), while Premium unlocks unlimited focus sessions, advanced posture & ergonomic coaching, the nutrition calendar, community challenges and leaderboards, the full weekly wellness recap, and premium reminder styles.

How we built it

Built by one person with a fleet of AI coding agents (vibecode-style: Claude agents reading project docs and writing code autonomously):

Mobile — Expo React Native (SDK 53) with expo-router, Zustand for persisted local state, TanStack Query for server state, NativeWind styling, and react-native-purchases for RevenueCat. Backend — Next.js 16 on Vercel: presence check-ins with IP geolocation, live pulse stats, mood endpoints, and NextAuth Google sign-in. Data — Supabase: Postgres with row-level security, Google OAuth, and Realtime channels for instant chat and the live globe of active users. Monetization — RevenueCat offerings, a premium entitlement, and a custom paywall shown after the user completes their first eye break or focus session — value first, ask later. The architecture is deliberately boring: a mobile client, a thin serverless API, a managed database. No VPS to patch, no servers to babysit.

Challenges we ran into

  1. A paywall with nothing behind it. We had a beautiful paywall from day one — three plans, a value list, restore purchases. Weeks later we realized the terrible truth: nothing was actually gated. Every feature the paywall promised was fully free. We had built a subscription button connected to nothing. Fixing it meant building a real entitlement layer across the entire app: free-tier limits on focus sessions, locked challenge cards, a premium-locked nutrition calendar, and a paywall that appears at the exact moment of first value.

  2. Fake community is a time bomb. A "global community" with zero users looks dead, so we faked it — "Join 47,000+ remote workers," seeded cities on the globe, participant counts everywhere. It wasn't just a trust problem; it was an App Store review problem and a refund problem. The first paying user to notice "12,453 participants" in an empty room would 1-star us into oblivion. We stripped every fake number and made the backend report real counts only.

  3. The invisible backend bug. A database migration had silently dropped the trigger that creates a user profile on sign-up. The app "worked" — but every mobile user was missing a profile row, causing foreign-key failures on chat and mood sync, and every active user showed up as "Anonymous." Cross-device sync was writing to a table that had never been created. The frontend looked perfect while the data layer was quietly rotting.

  4. App Store compliance isn't optional. Shipping for real meant in-app Terms of Use and Privacy Policy, an account-deletion flow (Apple 5.1.1), honest labeling of simulated health data, and an SDK upgrade path (Expo 53 is four majors behind — iOS 26 requires newer).

Accomplishments that we're proud of

A real-time community from scratch — Supabase Realtime chat rooms matched to the user's local workday phase, a live globe of active coworkers, and an honest global pulse. No third-party chat SDK. The trust pivot — we deleted every fabricated number from the product. The community is small and real, and that honesty is now the product. A genuinely adaptive wellness engine — daily quests generated from your pain areas, setup type, and streak; stretches sorted by your ergonomic profile; reminders with three distinct personalities. Cross-device sync — Zustand state pushed to Supabase snapshots and merged back on sign-in, so your day follows you. A production backend live on Vercel with geolocated presence and real user counts — the full stack works end to end. Built solo with AI agents — one person, a fleet of autonomous coding agents, and a shipping mindset.

What we learned

Subscriptions are a trust product. RevenueCat made the plumbing trivial — offerings, entitlements, restore — but the hard part is the contract with the user: gate real value, show the paywall after value is experienced, and anchor pricing on the impulse threshold: $ 39.99 12 ≈ $ 3.33 per month 12 $39.99 ​ ≈$3.33 per month

...a number that feels like "a coffee" rather than "a commitment."

Honest social proof beats invented scale. Small and real beats big and fake — for App Store review, for refunds, and for the community itself. Full-stack apps rot invisibly. The frontend can look perfect while migrations silently break the data layer. Migration hygiene is product hygiene. AI agents compound a solo founder's leverage. The bottleneck wasn't writing code — it was deciding what the product should be, and then auditing what the agents built.

What's next for Syncro - Remote Work Wellness

Launch. App Store submission is imminent: RevenueCat products configured, SDK 56 upgrade, TestFlight, and the launch run. Front-camera posture AI — slouch detection using the camera already in the app, like UPRIGHT but without the $199 hardware. Apple Watch companion + Home/Lock Screen widgets — retention multipliers for a habit app. Real HealthKit integration (steps, stand hours, sleep) replacing the simulated health card. Calendar-aware Meeting Mode — auto-pause reminders when the calendar says you're in a meeting. macOS menu-bar companion — the desktop gap no mobile-only competitor fills. A corporate wellness offering — when the community is big enough, sell the same product to employers, the way Personify and Sprout do. The North Star stays the same: make the remote workday feel a little less lonely, a little more human — one 20-second eye break at a time.
