COMPOUND stores data on-device and integrates with Apple's iCloud Keychain for encrypted backup. You can also export everything to CSV, JSON, or PDF at any time. Your backup, your choice.
COMPOUND uses Apple's Core ML framework for on-device machine learning. Pattern recognition, volume analysis, and recovery signals are all processed locally on your iPhone's neural engine. No data leaves your device.
Yes. COMPOUND supports CSV import from Strong, Hevy, Fitbod, and most other major workout trackers. We also support Apple Health data import for historical workout records.
Strong and Hevy are excellent loggers. COMPOUND is a fitness operating system — it connects workout tracking with daily journaling, programme management, and AI-powered insights. And unlike both, COMPOUND never requires an account or sends your data to a server.
Not yet. COMPOUND is built native iOS-first to deliver the best possible experience. We're focused on getting iOS right before considering other platforms.
Your data lives on your device, not ours. Even if COMPOUND disappeared tomorrow, you'd still have every workout, every journal entry, every document. That's the point of privacy-first.
COMPOUND requires iOS 17.0 or later. On-device AI features require an iPhone with an A14 chip or newer (iPhone 12 and above). Apple Watch features require watchOS 10.0 or later.
Go to Settings → Data → Export. Choose your format (CSV, JSON, or PDF) and select what to include: workouts, journal entries, projects, or everything. The export file is saved directly to your device or shared via the iOS share sheet.
COMPOUND is free to use with generous limits. Pro subscriptions are handled through Apple's in-app purchase system. You can manage or cancel your subscription at any time through your iPhone's Settings → Apple ID → Subscriptions. No tricks, no dark patterns.
