SmartClean: Media Cleaner is a calm, design-led way to care for your camera roll. Instead of noisy slogans, it offers a measured routine: see what takes space, make thoughtful selections, and gently give your device room to breathe. Every screen favors clarity, numbers, and touch interactions that feel precise and deliberate. What you can do • Photo & video size reduction Move into a dedicated Compression workspace for photos or videos. Select items in a clean grid, preview each item’s original vs. target size on the thumbnail, and view a running estimate of space you’ll regain before you proceed. Decisions stay reversible until you confirm. • Calendar-based media review Open a monthly calendar that surfaces your media footprint day by day. A compact, color-coded bar helps you sense how photos, videos, and other categories occupy space. Tap a date to review the content from that moment in time—maintenance turned into a simple daily ritual. • Smart groupings for careful curation When you prefer a guided pass, use quick groupings designed for human review: similar shots, soft/blurry frames, screenshots, duplicate photos and duplicate videos, plus sequences from Live Photos. You remain in control—select what stays and what goes with clear checkmarks and totals. • Thoughtful video collection view Browse all videos with durations visible at a glance. Multi-select to reduce file sizes or remove what you no longer need, with live feedback about how much space will be released. • Print the memories that matter Bridge digital and physical: connect to a home printer from the Photo printing tab, choose from the system album or take a new photo, and send it to print. Keeping a few images in your hands can be part of your routine, too. Design language SmartClean: Media Cleaner emphasizes restraint and legibility: generous spacing, soft gradients, and tactile cards. The interface turns storage care into a quiet practice—numbers first, no clutter, and a gentle sense of progress. It’s not another “one-tap miracle.” It’s everyday digital maintenance done with intention. Highlights • True photo/video compression with before/after sizes on each item • Live estimate of reclaimable space before you act • Calendar view to revisit specific days • Guided sets: similar, blurry, screenshots, duplicate photos/videos, Live Photos • System album integration and printer workflow Make space without the noise. Turn upkeep into a small daily ceremony—and keep what matters. • Payment will be charged to your iTunes Account upon confirmation of purchase (after the free trial period if offered). • Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. • Account will be charged for renewal within 24 hours prior to the end of the current period, and the renewal cost will be specified. • Users can manage their subscriptions and turn off auto-renewal by going to their Account Settings after purchase.
