Take a new photo or pick a photo from your photo library and then count objects on it by tapping them. Save screenshots and/or share them via email or social networks. Use the Line tool when you need to mark a sequence of objects with equal distances between them (note: this doesn't work well with object viewed in perspective). Use the Multiplication tool to count objects positioned in 'rows' and 'columns'.

DoorCodes keeps your saved access details ready when you actually need them. Save apartment buzzers, gate codes, garage entries, office suites, and other place-based access details in one calm, private app. When you get close to a saved place, DoorCodes can surface a privacy-safe reminder so you are not digging through notes, texts, or old emails at the door. DoorCodes is designed for everyday trust: - save places with one or more access codes - see Nearby and Recents views built around real arrival moments - keep lock-screen alerts privacy-safe - protect hidden codes with Secure Reveal - optionally sync through your private iCloud account Launch scope for v1 focuses on the iPhone and iPad core app experience. Apple Watch, widgets, and Live Activity remain out of the public launch promise, and Apple Watch is intentionally sidelined for this release unless launch scope changes in a later update.
