A world of discoveries. A collection of your own. A leaf on your walk. An old camera on your desk. Breakfast at a favorite cafe. CapWorld turns the things that catch your eye into a personal visual collection, one little discovery at a time. CAPTURE YOUR CURIOSITY Take a photo or choose one from your library. CapWorld lifts the subject out of the background and uses online identification to suggest a name, category and description. MAKE ROOM FOR ALL YOUR INTERESTS Nature, objects, food, toys, keepsakes and more. You choose what belongs in your collection. Your saved discoveries, called caps, are arranged by date and ready to revisit. GIVE YOUR FINDS A HOME Create collections around a trip, a hobby or a moment in your life. Add a name and introduction, then bring related discoveries together. A shelf of souvenirs can become a collection of travel memories. TAKE A CLOSER LOOK Open a cap to enjoy its details, swipe up to read, and browse through a collection. Edit names, categories and descriptions. If an identification needs correcting, provide a name and try again. SHARE A LITTLE OF YOUR WORLD Turn a single cap or an entire collection into a shareable image. Save it to Photos or send it through the iOS share sheet. KEEP YOUR DISCOVERIES CLOSE Saved caps stay on your device. Plus subscribers can enable iCloud sync in Settings to keep caps, images and collections in sync across devices using the same iCloud account, and recover synced content after reinstalling or changing devices. Start without creating an account, export and import backups, and enjoy light and dark appearances with multiple app languages. The free version includes up to 10 caps and 1 collection. Optional CapWorld Plus auto-renewing monthly and yearly subscriptions provide more room for caps and collections. Prices and available offers are shown in the app. Manage or cancel your subscription in your Apple Account settings. Online identification requires an internet connection and may be inaccurate.
