Optimize and Clean Your Android with DU Speed Booster (Cleaner)
DU Speed Booster (Cleaner) is a free all-in-one optimization app for Android that improves device performance, frees up storage space, and enhances system speed with just a few taps. Packed with powerful features and a user-friendly interface, it’s designed for users who want to keep their devices clean, fast, and secure.
Boost Performance Instantly
One of the core features is the Accelerator, which instantly clears up RAM by closing background apps that aren’t needed. This can dramatically improve speed and responsiveness, especially for users with older devices or limited memory.
With a real-time view of running apps, users can manually choose which processes to stop—putting more control into your hands for a custom optimization experience.
Clear Junk and Reclaim Storage
The Trash Cleaner scans and removes unnecessary files such as cache, residuals, obsolete APKs, and temporary data. This not only frees up valuable space but also helps maintain the long-term health of your device by preventing data buildup over time.
Advanced Internet Speed Testing
DU Speed Booster also includes a built-in Network Speed Test feature that checks your upload and download speeds, as well as ping performance. Unique to this tool is a global comparison system, allowing you to see how your connection stacks up against other users around the world.
It keeps a history of your past tests, making it easier to spot fluctuations or performance issues with your network over time.
Powerful App and APK Management
The App Manager lets you uninstall apps with one tap, review install dates, and see how much storage each app occupies. Meanwhile, the APK Manager helps you clean up unused installation files and manage APK installations directly from the interface.
Need more space? Use the Move to SD Card option to transfer supported apps to external storage. There's also a Top Free tab that recommends popular apps tailored to your interests.
Security and Privacy Features
DU Speed Booster (Cleaner) includes a built-in antivirus engine that scans for potential malware and threats. Additionally, the Permissions Manager provides insights into which apps have access to your device’s sensitive features—offering an added layer of privacy and security.
Game Booster for Smoother Gaming
The dedicated Game Booster function enhances performance during gameplay by allocating maximum resources to the game and minimizing background activity. This results in faster loading times and smoother gameplay, especially for graphics-intensive mobile games.
Visually Appealing and Easy to Use
DU Speed Booster features a clean and modern interface, with intuitive navigation that makes it accessible for beginners and power users alike. All core features are easily accessible from the main dashboard—Accelerator, Cleaner, App Manager, Speed Test, Security, and more.
The app also provides visual reports after each optimization process, giving you instant feedback on performance gains.
Battery Saver and Additional Tools
While the Battery Saver function is accessible via the main interface, it redirects users to a separate app on Google Play for full battery management. Pairing both apps can further enhance battery longevity and background app control.
A Reliable Alternative to Other Optimizers
Whether you're comparing with Clean Master, AMC Security, or other optimization tools, DU Speed Booster (Cleaner) stands out with its combination of speed, security, and storage management. It’s ideal for users who want a comprehensive tool that boosts performance without compromising usability.
