FAQ
Common questions.
How accurate is the AI body fat estimate?
AI estimates are approximations, not medical measurements. The most useful signal is the trend across consistent weekly photos.
What does Coach know?
Coach can use your check-ins, AI scores, body metrics, Health data, workout history, nutrition logs, and selected photo comparisons when those sources are available.
Are my photos private?
Your photos are sent securely for AI analysis and are never stored outside your device by GainFrame.
Can I import old gym selfies?
Yes. Smart Import classifies old photos by pose and builds your transformation timeline automatically.
