A Habit Tracker App Boilerplate Built Around Local-First Data and a Paywall

Why a habit tracker should be local-first

A habit app lives or dies on friction. The user opens it once or twice a day to tap a checkmark, and if that tap waits on a network round-trip, the habit of using your app breaks before theirs does. The Swift Kit's habit tracker boilerplate is local-first: every habit, daily check-in, and computed streak lives on-device, so the grid renders instantly and a tapped checkmark commits with no spinner, on the subway or on a plane. Cloud sync is an enhancement, not a dependency. Supabase is wired in as the backend — auth, Postgres, storage — but you can ship a genuinely useful free tier with zero account required, then layer sync and Sign in with Apple on top when a user wants their streaks on a second device. That ordering matters: offline-first first, sync second, account-gated never for the core loop.

• On-device storage for habits, check-ins, and streak history — instant reads, no network
• Streaks and completion stats computed locally so the dashboard never waits on a server
• Optional Supabase sync (auth, Postgres, storage) added only when the user opts in
• Sign in with Apple available but not required to start tracking habits

The paywall that pays for the classic indie habit app

The proven monetization shape for a habit tracker is a generous free tier plus a paywall: track up to three habits free, pay to unlock unlimited habits, full history, custom reminders, themes, or widgets. The Swift Kit ships that exact shape with RevenueCat — a paywall screen, subscriptions, and multi-tier entitlements — so the only decision left to you is where to draw the line between free and premium. Entitlement checks gate features by a boolean, so 'unlimited habits' or 'detailed insights' is one flag away from working. Because RevenueCat handles receipt validation, restores, and price localization, you skip the part of habit-app development that has nothing to do with habits and everything to do with App Store edge cases.

• Pre-built RevenueCat paywall screen, ready to retheme to your brand
• Multi-tier entitlements to gate unlimited habits, history depth, themes, or widgets
• Restore purchases, receipt validation, and price localization handled for you
• Paywall is a feature flag — ship free-only first, switch monetization on later

What you build vs. what's already done

With persistence and payments solved, your work is the habit domain itself, and that is exactly where you want to spend your time. You define what a habit is (binary, count-based, or timed), design the calendar or grid view that shows the streak, and decide your reminder cadence — push notifications are already supported, so a 'remind me at 8pm' toggle is wiring, not infrastructure. The centralized DesignSystem.swift lets you retheme the whole app from one file, which is how indie habit apps end up looking custom instead of like a template: pick one of five surface styles (including Liquid Glass on iOS 26+), set your accent color, and the streak grid, paywall, and onboarding all follow. Three onboarding styles ship in the box, and the 3-step flow that asks a new user which habit they want to build first doubles as your highest-converting moment.

When The Swift Kit is the wrong choice for your habit app

Be honest with yourself about scope. If your habit tracker's entire reason to exist is deep HealthKit integration — pulling steps, sleep, or workouts as automatic habit completion — The Swift Kit gives you the SwiftUI shell and monetization but not a HealthKit data layer, and you'll write that part yourself. If you want a cross-platform habit app on Android too, a native iOS boilerplate is the wrong tool and you should look at the cross-platform comparisons below. And if you are purely learning Swift and never plan to charge, the paywall and Supabase wiring are weight you don't need yet — a free tutorial path may serve you better. The boilerplate earns its $99 when you intend to ship a monetized, iOS-first habit app and want the local-first data and paywall already standing.
