How accurate is a body fat calculator from a photo?

PhysiqueAI's AI is trained on hundreds of thousands of data points validated against DEXA scans. While not meant to replace clinical measurements, it provides consistent tracking for monitoring progress week over week. The consistency makes it reliable for tracking real trends in body composition changes.

Is this body fat calculator actually free?

Yes. The free tier includes 3 scans per month, body fat percentage, muscle mass, and 30 days of history. No credit card is required. Pro ($9.99/mo) unlocks unlimited scans, longer history, and predictive insights, but you can use it free forever.

How is this different from a navy body fat calculator?

Navy body fat calculators require you to measure your neck, waist, and hips with a tape measure. This is tedious, easy to mess up, and hard to do consistently. PhysiqueAI only needs a photo - no measurements, no math, no tape measure required.

What is a healthy body fat percentage?

For men: 10-20% is considered fit, athletes are often 6-13%. For women: 20-30% is healthy, athletes typically range 14-20%. Below essential fat levels (2-5% men, 10-13% women) is dangerous. The calculator shows where you fall and helps set realistic goals.

How often should I measure my body fat?

Once or twice a week works best, at the same time of day (morning is ideal) and same lighting if possible. Daily measurements add unnecessary noise since body fat doesn't change that fast. Weekly measurements give you real trends without the stress.

What happens to my photos?

Photos are encrypted and processed automatically. No human ever sees them. You can delete all your data anytime from settings.

Do I need any equipment to use the body fat calculator?

Just your phone. Any smartphone camera works. A mirror helps for framing the shot. Good lighting makes analysis more accurate, but it doesn't need to be perfect. No gym, no scale, no calipers required.

People Actually Use This

"I was getting DEXA scans monthly. This is close enough for tracking and saved me hundreds. Plus I actually check it more often now."
