【Core Features】
1. Smart Storage Cleaning (Clean)
Similar & Duplicate Photo Detection: Automatically scan and group burst photos, similar landscapes, or duplicate images. Our smart algorithm identifies and highlights the "best shot" in each group, allowing you to delete the rest safely with one tap.
Screenshots & Large Videos: Quickly categorize and review all screenshots and massive video files that are eating up your storage.
Visual Storage Overview: Get a clear, real-time breakdown of your device's storage and see exactly how much space you can reclaim.
2. High-Efficiency Video Compression (Compress)
Lossless & Low-Loss Compression: Compress large video files directly in your library. Choose from High Quality (original resolution, reduced bitrate), Medium Quality (720p balance), or Low Quality (480p extreme shrink) modes.
Reclaim Massive Space: Save 50% to 90% of video storage size with virtually no noticeable loss in visual quality.
3. Secure Private Vault (Vault)
Double-Layer Protection: Keep your sensitive photos and videos locked away behind a secure passcode and Face ID / Touch ID.
Lossless Import: Import private media into an isolated, encrypted local vault, completely hidden from your system photo library.
Auto-Delete Originals: Enable automatic deletion of original files after importing to the vault, eliminating the hassle of manual double-deletion.
4. Contact Slimming (Contacts)
Merge Duplicate Contacts: Scan your address book to find and merge duplicate names or phone numbers instantly.
Clean Incomplete Contacts: Identify and clean up contacts with missing phone numbers, emails, or names to keep your contact list neat and organized.
