Is it working? After a facial treatment, or weeks into a new skincare routine, that question is hard to answer from memory β€” and ordinary selfies shift with every take: a different angle, a different distance, chin a little higher. Face Still takes your selfie the same way every time, so a photo from today and one from a month ago can honestly be compared. THE SAME SELFIE, EVERY DAY β€’ Short on-screen prompts guide you into position β€” β€œLower your chin slightly”, β€œMove back a little” β€” and the photo takes itself the moment your pose, distance and expression match. No shutter button, no guesswork. β€’ Every photo lands on a calendar, so a month of your face fits on one screen. β€’ Add notes and tags β€” β€œnew moisturizer”, β€œslept badly” β€” and find them again with search. COMPARE ANY TWO DAYS β€’ Stack them, old above new, or drag a divider across one photo to reveal the other. β€’ Pan and zoom both photos together, so you are always looking at the same spot on your face. β€’ A 3D model of your face is saved alongside every photo, for reference. WATCH THE WEEKS PASS β€’ Turn your photos into a short video with your own music, saved to your Photos β€” weeks of your record in a few seconds. The app never judges what it sees. There is no score, no rating and no advice β€” just two photos taken under the same conditions, and your own eyes. No account. Your photos stay on your phone. They are not uploaded unless you turn on iCloud Sync, which is off until you turn it on. The app sends anonymous usage statistics so it can be improved. Your photos, notes and tags are never sent. This app is for your own record-keeping only, not a medical diagnostic or precision measurement tool.
