Master Cleaner - Clean Storage

What it does

Master Cleaner is a comprehensive utility app for iOS designed to help users reclaim storage space and organize their digital life. Its primary function is to scan and identify similar or duplicate photos, videos, and contacts, making it easy to delete unwanted files in bulk. Beyond cleaning, the app bundles a suite of secondary tools, including an AI-powered photo enhancer and restorer, a secure vault for private media, customizable widgets, and unique charging animations.

Where it shines

The app excels at making tedious tasks feel efficient and even engaging. The core cleaning flow for photos is straightforward, categorizing clutter into 'Similar', 'Duplicates', and 'Blurred' for easy review (01:22). A standout feature is the swipe-based interface for clearing out videos (02:47), which turns a chore into a quick, game-like interaction. Furthermore, the AI-powered photo restoration tool shows a compelling before-and-after comparison (04:39), effectively demonstrating its value with a single gesture.

UX highlights

Contextual Permissions: The app requests access to Photos, Contacts, or Calendar only when the user tries to use a feature that requires it (e.g., Calendar access at 03:23), making the requests feel logical and necessary.
Gamified Swiping: The swipe-left-to-delete, swipe-right-to-keep mechanic for cleaning videos (02:47) and blurred photos (02:15) is a fast and satisfying way to handle bulk file management.
Clear Success States: After every deletion, a congratulatory screen (01:34) appears, confirming the action and quantifying the space saved. This provides positive reinforcement.
Bundled Value: The main dashboard (01:14) neatly organizes a wide range of tools, presenting the app as a multi-purpose utility suite rather than a single-function cleaner.
Visual Previews: Features like charging animations offer a full-screen preview (07:58) before the user commits to setting them up, reducing uncertainty.
Guided Setup: For complex actions like setting up widgets or charging animations, the app provides clear, step-by-step visual tutorials (08:06), reducing user friction.

Monetization & growth

The app employs a hard paywall strategy, requiring a subscription to access any of its features. During onboarding, after a detailed feature carousel, the user is prompted to start a 3-day free trial, which converts to a $4.99/week subscription (00:58). The entire onboarding flow is designed to build a strong case for the app's value before this paywall appears. Certain features, like specific charging animations, are also marked with a 'Pro' badge within the app, reinforcing the value of the subscription.

Who it’s for

Master Cleaner is targeted at iPhone users who are running low on storage space or feel overwhelmed by digital clutter. Its primary audience likely consists of non-technical users who want a simple, all-in-one solution for cleaning photos, contacts, and videos. Secondary users might be drawn in by the novelty features like AI photo editing and custom charging animations, seeing the app as a tool for both utility and personalization.

Notes & opportunities

While the app is feature-rich, the sheer number of tools could potentially cause a lack of focus. The main dashboard is well-organized, but the connection between 'cleaning' and 'charging animations' feels tenuous. The app could benefit from clarifying its core identity. Additionally, the process to set up charging animations relies on the user navigating the complex iOS Shortcuts app (08:12), which could be a significant drop-off point for less tech-savvy users.
