Compound

An iOS workout tracker with routines, live set logging, a rest timer, progress charts, and a daily bodyweight and food log.

App Store

Notice: This app is no longer available on the App Store. Apple Developer subscription expired.

Features

• Build routines from a 24-exercise starter library, or add your own from any picker
• Live workouts with a session timer and grey "ghost" hints of last time's reps and weight
• Manual rest timer with presets, sound, haptics, and a notification if you leave the app
• Minimize a workout to a mini bar, or follow it on the Lock Screen and Dynamic Island
• Resumes an interrupted session after a crash or force-quit
• Workout log grouped by month, fully editable, with save-as-routine
• Stats for streaks and training frequency, plus lift progression by top set, est. 1RM, or volume
• Body tab for bodyweight, calories, protein, and a paste-friendly food log
• lb/kg units that convert every saved weight, light/dark themes, JSON export
• Offline: no account, no network, everything local in SwiftData

Requirements

• iPhone running iOS 17.0 or later
• Xcode 16.0 or later (for development) — the project uses file-system synchronized groups

Installation

1. Clone and open Compound.xcodeproj in Xcode
2. Set your own bundle identifier and signing team on both the Compound and CompoundWidgets targets
3. Build and run
4. Create a routine, start a workout, and log your first set

Configuration

Demo Data (DEBUG)

Seeds a push/pull/legs block over the last seven weeks, three routines, and a month of body entries.

From the app: Profile → Developer → Seed Demo Data / Wipe All Data.

By launch argument:

-seedDemoData
-wipeData

xcrun simctl launch booted Oriented.Compound -seedDemoData

In Xcode's scheme editor each argument must be its own row — -seedDemoData YES on one row matches nothing and silently does nothing. Seeding is idempotent, so leaving it on is safe. None of this ships in Release.

Live Activity

1. Start a workout from Routines
2. Lock the device or simulator (⌘L) — the activity shows the rest countdown, or elapsed time when not resting
3. Tap it to reopen and maximize the workout

Live Activities run in the Simulator; the expanded Dynamic Island needs a physical device to long-press.

Tests

xcodebuild test -project Compound.xcodeproj -scheme Compound \
  -destination 'platform=iOS Simulator,name=iPhone 17 Pro'
