About HowTall

HowTall is an innovative iOS application that leverages LiDAR technology and ARKit body-pose estimation to measure a person's height in real time. Designed for iPhone Pro users with LiDAR sensors (iPhone 12 Pro or later), it allows users to simply point their device at someone and instantly get an accurate height reading in centimeters or feet/inches. Its fully on-device processing ensures user privacy, as no data is sent to servers, and all camera and depth frames are discarded after processing. The app's ease of use and privacy focus make it ideal for health, fitness, or casual use cases where quick, reliable height measurements are needed without the hassle of manual tools or external devices. Its integration of AR and LiDAR technology makes it a standout for those interested in augmented reality applications and real-time measurements, offering a seamless and modern approach to a common need.
