For many iPhone users, managing local storage is a recurring and frustrating task, often prompted by persistent system alerts when space runs low. CleanSlate: Clean Storage positions itself as a dedicated solution for this problem, providing a focused set of tools to analyze and purge superfluous data. Unlike built-in iOS storage management, it aims to offer more granular control and clearer visualization of what is consuming space, targeting the cache files, app leftovers, and duplicate media that can accumulate unnoticed. The app's functionality centers on its Smart Analysis engine, which performs a deep scan of the device's storage. Core features include a junk file cleaner that targets temporary caches from apps and browsers, a duplicate photo and video finder that uses content matching, and a large file tracker that sorts items by size. A notable feature is the app-specific cleaner, which allows users to see the storage footprint of individual applications and selectively delete their cached documents and data without removing the app itself. This is particularly useful for social media or streaming apps, which can silently amass several gigabytes of offline data. In practical use, the interface is straightforward, presenting scan results in clearly categorized sections. The process from scan to cleanup typically takes under a minute, and users can review items before deletion. A real-world scenario involves using CleanSlate before downloading a large iOS update or installing a new game, quickly freeing up the necessary 5-10 gigabytes. The app also provides historical data on space cleaned, offering tangible proof of its utility. However, it operates strictly on local device storage and does not integrate with or clean cloud services like iCloud Photos, which is a conscious limitation of its scope. As a relatively new app, published by SUNNYSIDE TECHNOLOGY PTY. LTD., user feedback is still emerging, but early adopters appear receptive. Reviews indicate satisfaction with the amount of storage reclaimed, often citing figures between 8 to 15 GB on cluttered devices. Some users note the duplicate photo finder as a standout, successfully identifying similar shots from bursts or multiple downloads. A minor critique mentioned in feedback is the desire for more customizable filters within the large file viewer, such as sorting by file type or date last accessed. Overall, CleanSlate delivers effectively on its core promise. It excels in providing a clear, actionable overview of storage usage and automating the cleanup of low-hanging fruit like cache data. The lack of cloud integration keeps its focus narrow, which can be a strength for users wanting direct device control but a limitation for those seeking a holistic solution. For the price, it serves as a competent and specialized utility for routine storage maintenance.
