Make room for the photos you want to keep. Smart Cleaner helps you review duplicate and similar pictures, sort your library, and compress large photos on iPhone and iPad. REVIEW DUPLICATES & SIMILAR PHOTOS Scan your accessible photo library and compare suggested groups. Choose which photos to keep and confirm deletions yourself. SWIPE THROUGH YOUR LIBRARY Review photos one at a time and choose to keep or delete them with a swipe. COMPRESS LARGE PHOTOS Choose from three quality levels to reduce image file size. Compression can change image quality; results depend on the original photo and your settings. Photos may retain originals for reverting edits, so a smaller image does not guarantee an immediate increase in available device storage. MORE WAYS TO ORGANIZE - Review suggested duplicate contacts and clean up selected entries. - Browse past calendar events and delete those you no longer need. - Store private photo copies in an encrypted local vault with Face ID or Touch ID on supported devices. Premium is required. Importing a photo does not remove its original from Photos. - View your cleanup activity history. PRIVACY & ACCESS Photo analysis and vault encryption run on your device. Access to Photos, Contacts, Calendar, and biometrics is requested for the relevant features. See the privacy policy for details about data handling and third-party services. PREMIUM Photo cleanup does not require a subscription. Premium offers monthly and yearly auto-renewing subscriptions and a one-time lifetime purchase. Available offers and prices appear in the app. Payment is charged to your Apple Account. Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel subscriptions in your App Store account settings.

This does not filter iMessage or messages from contacts. Calls are blocked only by exact international numbers; the allow list takes priority. Message rules do not analyze or block calls. Processing is local, and the app does not receive a system blocking log. Matching is not a fraud diagnosis and may miss or misclassify messages. Review and test rules before enabling them.
