CalmHabits – Habit Tracker iOS App Template (SwiftUI + SwiftData)

CalmHabits is a complete, ready-to-publish habit tracking app built entirely with SwiftUI and SwiftData. It features beautiful GitHub-style completion grids, streak tracking, smart reminders with local notifications, a premium paywall with in-app subscriptions, iCloud sync and full dark mode support. No third-party dependencies – 100% native Apple frameworks.

Demo Instructions

No login required – the app is fully offline and works out of the box. There are no demo credentials.
On first launch you will see a short onboarding flow. Complete it to reach the main app.
Tap the ”+” button to create your first habit, pick an icon, a color and set reminder days.
iCloud sync activates automatically when the user is signed into iCloud on the device (the app falls back to local storage otherwise).
The in-app subscription products (“calmhabits_y” yearly and “calmhabits_m” monthly) must be configured in your App Store Connect account for real purchases. Until then the app works perfectly with the free tier (up to 3 habits).
