Common Questions
Can I sync my data across devices?
Yes! Enable iCloud Sync in Settings to seamlessly sync your food log, targets, and weigh-ins across all your Apple devices.
Is my data private?
Absolutely. We don't collect analytics, track usage, or share your data with anyone. Everything stays on your device or in your personal iCloud account. See our Privacy Policy for details.
How do I bring my history from Lose It, MyFitnessPal, or Cronometer?
Settings → Import from Health → All time. Compound Fuel pulls every dietary sample your old app wrote to Apple Health and rebuilds your log from day one — including your streak, up to 10 years back.
How do training days bump my macros?
Compound Fuel reads HKWorkout from Apple Health (written by Compound Theory or Apple Watch) and auto-increments your protein and carb targets on any day you logged a strength workout. No manual toggle — the app sees the workout and bumps the day.
What's the difference between Free and Pro?
Free: unlimited logging, barcode scanning (20/mo), algorithmic targets, weekly check-in, Apple Health integration, iCloud sync. Pro: USDA food search, unlimited barcodes, advanced analytics (adherence %, 8-week trend, split training-day TDEE), milestone badges, Live Activity, multi-nutrient widget configuration, alternate app icons, CSV export.
