A native iOS app for the 75 Hard mental toughness program. Track your daily tasks, stay honest, and complete all 75 days — no exceptions.

Phase 1 — Offline Core (Current)

• Daily Checklist — See all 6 tasks the moment you open the app. Check them off throughout the day.
• 75 Hard Defaults — Two 45-min workouts (one outdoor), diet adherence, 1 gallon water, 10 pages reading, progress photo.
• Customizable Targets — Adjust water amount, page count, and task labels to fit your needs.
• Workout Stopwatch — Full-screen timer with indoor/outdoor toggle, workout type, and duration tracking.
• Reading Log — Dedicated tab with page-count grid and reading history.
• Day Progress — Circular progress ring and 75-bar strip showing completed vs. remaining days.
• Soft Reset — If you miss a day, the app lets you decide: restart from Day 01 or dismiss. No auto-resets.
• Offline First — Everything works without internet. Data is stored locally via SwiftData.
• Minimalist Design — Monochrome, distraction-free interface with sharp corners, hairline dividers, and haptic feedback.

Coming Soon

• Progress Photos — In-app camera capture and 75-photo gallery (Phase 3)
• Calendar History — Day-by-day calendar view of completed and missed days (Phase 2)
• Smart Reminders — Adaptive push notifications (Phase 4)
• Cross-Device Sync — Sign in with Apple and sync via Supabase (Phase 2)

Key patterns:

• @Observable ViewModels for business logic
• @MainActor Services for data operations
• SwiftData @Query for reactive view updates
• @AppStorage for simple user preferences
• VersionedSchema with MigrationPlan for safe schema evolution
• Timezone-safe DayID generation (YYYY-MM-DD in user's local timezone)

• Xcode 16+
• iOS 17.0+ deployment target
• Swift 6

1. Clone the repository:

   git clone https://github.com/anomalyco/quanta.git
   cd quanta

2. Open the project in Xcode:

3. Select the Quanta scheme and run on a simulator or device.

No third-party dependencies are required for Phase 1. Supabase SDK will be added in Phase 2.

xcodebuild test -scheme Quanta -destination 'platform=iOS Simulator,name=iPhone 16'
