Habbitly

Habbitly is a complete native iOS habit tracker built in SwiftUI with SwiftData persistence. Track daily, weekday or custom schedules (including quantitative habits with target values), log or correct check-ins retroactively from any past day in a habit's calendar history, and follow your progress with completion rates, a monthly heatmap, a streak leaderboard and weekly averages. It runs 100% offline with no backend, accounts or tracking.

Highlights

• Streak engine with current streak, best streak and completion rates, unit-tested across month boundaries and DST transitions
• Retroactive logging: tap any past day to log or fix a check-in
• Per-habit local reminders with a "Mark Completed" quick action that writes straight to the store
• Siri Shortcuts via App Intents: "Log a habit in Habbitly" works from Siri, Shortcuts, Action Button and Back Tap
• RFC 4180-safe CSV export of all habits and history, with spreadsheet formula-injection protection
• StoreKit 2 paywall scaffold: monthly subscription plus lifetime unlock, testable locally with the included .storekit configuration
• Habit form with icon and color pickers, categories with filter chips
• Animated splash and 3-page onboarding flow
• One-file re-skin via the AppTheme token enum, with a second pre-captured indigo theme shown in the screenshots

Technology
