Question: Is there a platform that allows users to take body measurements using just a smartphone, and provides accurate data for personalization?

If you're looking for a service where people can take body measurements with just a smartphone, Bodygram is a good choice. The system uses a smartphone-based scanning process that requires two photos and some basic information like height and weight to generate measurements, posture angles and a 3D avatar. Bodygram protects users' privacy and security, and offers a free version with up to 20 body scans per month.

Another service worth mentioning is Body Scan, an AI-powered fitness service that generates a personalized workout plan based on body data it calculates from a full-body selfie. It offers details on body fat percentage, daily caloric needs and macronutrient ratios, and can be used to generate a personalized fitness plan. The service is free and prioritizes privacy and security, so it's a good option for people who want to take a data-driven approach to fitness.

If you're looking for a service that can give you accurate size recommendations, WAIR is a good choice for e-commerce sites. WAIR, which has a large 3D body scan database, can give personalized size recommendations based on body type and how a product fits. That can help cut return rates and boost customer satisfaction, so it's a good option for online retailers.

Last, Fit Analytics offers size advice to apparel e-commerce sites based on body measurements and purchase history. Its Fit Finder feature can ensure the right size is ordered the first time, cutting down on returns and boosting customer satisfaction. It can be integrated with e-commerce sites, so it's a good option for retailers that want to offer a better shopping experience.
