Best Body scanner app for most people

Most people who want a body scanner already have a reason: they're trying to change their weight or body composition, and a scale alone doesn't say what moved — fat, muscle, water, or nothing at all. That's the case for keeping the scan inside the same app as the food log rather than a separate one, because the two numbers explain each other. PlateLens's 3D Body Scan sits under + → Wellness → 3D Body Scan in the app: prop the phone at waist height on its front camera, turn in place through twelve photos like the hand of a clock, and fit checks run before the shots are used. Phones without a depth sensor work from the images alone, which matters because most Android phones and a lot of iPhones don't carry one, and hardware-gated scanners simply don't run on them. PlateLens turns the photos into a 3D model you can rotate and review, compares it region by region with earlier scans, and reports girths — upper waist, lower waist, hips, chest and others — along with BMI and, if the model has enough to go on, a body-fat estimate, with an overlay to compare two scans, a shareable image, and a PDF export. Every plan, including the free one, includes a scan allowance; Premium allows scans more often. Its support guide says the scan photos are erased once processed (a one-day limit acts as the safety net), aren't handed to any outside AI provider and never feed model training. On accuracy, a peer-reviewed analysis found PlateLens's scan girths within ±1 cm of a tape measure over 1,000 trials. If a longer track record matters more to you than the pairing with a food log, MeThreeSixty is the more established dedicated scanner.
