GoPilates — a French-first Pilates app on the App Store. ~13k LOC of SwiftUI, a 37-screen onboarding funnel, RevenueCat-powered subscriptions, HealthKit integration, Lottie animations, and Tenjin attribution. iPhone-only, iOS 17+, shipped for the client (DRF GROUP LLC). This repo is the public archive of the build.

/// THE BRIEF

Build a Pilates app for francophone users that feels less like a fitness tracker and more like a guided studio — emotional onboarding, body-zone targeting, weight-projection visuals, and a subscription that converts because users have already invested 37 screens into their plan. RevenueCat handles the paywall, HealthKit logs the workouts, Tenjin tracks the install attribution. Apple's App Store, no Android.

/// HIGHLIGHTS

37-screen onboarding funnel	Goal, body-type, current/target weight, fitness level, daily life, difficulty, emotional drivers, affirmations, future pacing, social proof — the full BetterMe-style conversion arc. Implementations live under GoPilates/Onboarding/.
RevenueCat subscriptions	Centralised in SubscriptionManager. Free trial → paid plans configured via RevenueCat's dashboard, not hardcoded in the app. StoreKit config for local testing in Configuration.storekit.
HealthKit integration	HealthKitManager — workouts log into the Apple Health app, contributing to Activity rings. Read + write usage strings declared in Info.plist.
Tenjin attribution	TenjinService — install attribution + event tracking for paid ads. Per-event guard against the deprecation warnings the SDK throws on iOS 17+.
Workout player	WorkoutPlayerView — timed exercise loops with audio cues, WorkoutTimerService drives the countdown, Lottie animations on visual states.
AudioManager	AudioManager — plays through .mixWithOthers so a Pilates session doesn't clobber the user's music.
XcodeGen project	project.yml → .xcodeproj regenerated from spec. Easier for code review, easier for CI.
Xcode Cloud CI scripts	ci_scripts/ — pre-build hooks for App Store builds.
iPhone only	TARGETED_DEVICE_FAMILY = "1" — no iPad layouts, no Mac Catalyst. Portrait only.

/// LOCAL DEV

# 1. Generate the .xcodeproj from project.yml (if XcodeGen isn't installed):
brew install xcodegen
xcodegen generate

# 2. Open in Xcode
open GoPilates.xcodeproj

# 3. RevenueCat: the publishable iOS API key in GoPilatesApp.swift is the
#    PUBLIC key (designed for client-side use, like a Stripe publishable
#    key). For your own builds, swap it for your own app key.

# 4. For local subscription testing, use the bundled Configuration.storekit
#    file as the StoreKit configuration in the run scheme.

Requires Xcode 16+. Runs on iOS 17+ devices (project deployment target is 18.0; App Store binary serves 17.0+).
