Frequently Asked Questions
How does LeanTrack calculate my calorie target?
LeanTrack uses the Mifflin-St Jeor formula with your activity level to estimate your TDEE (Total Daily Energy Expenditure), then applies a 500 kcal deficit for a safe fat loss pace of ~0.5kg per week. If your body fat is high, it uses lean body mass to set protein targets.
How is body fat % calculated?
We use the US Navy circumference method — neck, waist, and hip (women only) measurements against your height. It's not as accurate as a DEXA scan but is a reliable and consistent way to track changes over time.
Why is my weight fluctuating so much day to day?
Daily weight fluctuations of 0.5–2 kg are completely normal. They're caused by water retention, food volume, sodium, and hormones — not actual fat gain or loss. LeanTrack's weekly average trend is the most accurate way to track real progress.
Does LeanTrack sync with Apple Health?
Yes. LeanTrack reads steps, active calories, and walking distance from Apple Health automatically. Make sure you grant permission when prompted, or go to Settings → Health → LeanTrack to enable access.
How do I delete all my data?
Go to Profile → scroll to the bottom → tap "Delete All Data". This permanently removes all weight entries and your profile. This action cannot be undone.
Is my data stored on the cloud?
No. All your data is stored locally on your device using Apple's SwiftData framework. We do not collect, transmit, or store any personal data on external servers.
How do I enable weight reminders?
Go to Profile → Notifications → toggle on Morning, Afternoon, or Evening reminders. Make sure you've granted notification permission to LeanTrack in your iPhone Settings.
I found a bug. How do I report it?
