Designed for the discerning. Powered by your iPhone's TrueDepth camera. Crafted entirely on-device. OpticALLY captures a sub-millimeter 3D scan of your face and computes the exact measurements an optician would take by hand — pupillary distance, bridge, temple, frame and lens width, and more — in seconds. No fitting room, no caliper, no guesswork. — FEATURES — ▸ Export your face in 3D Every scan can be exported as an .OBJ, .PLY, or .USDZ file. Drop it straight into Blender, Fusion 360, ZBrush, or Unity. 3D-print a digital twin, build a custom avatar, or design eyewear that fits only you. ▸ More accurate than LiDAR The front-facing TrueDepth camera projects thousands more depth points onto your face than the rear LiDAR scanner — delivering approximately 0.5 mm of measurement precision. The same hardware Apple trusts for Face ID, repurposed for optical-grade fitting. ▸ Twelve clinical measurements, in real time Binocular and monocular PD, bridge width, nose width, nose length, temple length, frame width, lens width, face width, face height, cheekbone width, jawline width. Every dimension your optician asks for, captured and displayed instantly. ▸ Privacy as a feature, not a footnote Every scan is processed locally on your iPhone. No cloud. No server. No data collected, transmitted, or stored. Your face is yours alone — measurements live in the app, and scan files are discarded when you close it, unless you choose to export them yourself. ▸ OpticALLY Pro Unlock the full measurement set, export, and on-device 3D mesh reconstruction with an OpticALLY Pro subscription. Restore prior purchases anytime from Settings. — REQUIREMENTS — OpticALLY requires an iPhone with a TrueDepth front camera (Face ID). iPads are not supported at this time. — PRIVACY — Privacy policy: https://wonmor.github.io/OpticALLY-iOS/ — TERMS — Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
