Keeping your phone clean and organized isn’t just about aesthetics, it’s also about performance. Over time, devices accumulate unnecessary files, cache, app remnants, and duplicate data that take up space and slow down the device. Fortunately, there are several free apps available for Android and iOS that can help you clean up your phone quickly and effectively. You can download each of the apps mentioned below.

1. CCleaner

CCleaner is one of the most popular cleaning apps in the PC world and has now been optimized for mobile devices. It is ideal for those looking for a complete solution to remove junk files, free up space and monitor their phone's performance.

Its main features include clearing cache, browsing history and residual files from previously uninstalled apps. The interface is intuitive and allows users to see what is taking up space on their phone before confirming the deletion. In addition, the app offers a dashboard to analyze CPU, RAM and battery usage — great for those who want to understand what is affecting their device's performance.

CCleaner also has intelligent cleaning suggestions and does not perform any deletions without the user's authorization. It is an excellent choice for those who want to keep their device light and functional, without complications.

2. Files by Google

Files by Google is a multi-functional app that goes far beyond simple cleaning. It combines file management functions with powerful system organization and optimization tools. Ideal for those who want a lightweight, functional and ad-free app.

With it, you can find and delete duplicate files, old memes, blurry photos, app cache, and even large files that take up space unnecessarily. The app also suggests automatic cleaning actions based on device usage, making the experience practical and personalized.

Another difference is the ability to transfer files between devices without the internet, using only a local connection. Files by Google is perfect for users who value simplicity and efficiency when organizing and speeding up their cell phone.

Developed by the same company that makes the famous antivirus, Avast Cleanup is a free app that combines deep cleaning with advanced optimization features. It not only removes unnecessary files but also helps improve the overall performance of your smartphone.

The app analyzes the phone's internal memory and identifies temporary files, cache, thumbnails and application residues. Users can choose to perform a quick or detailed cleanup, as well as receive personalized suggestions to save space. One of its biggest features is “Hibernation Mode,” which freezes apps in the background to save battery and free up RAM.

Avast Cleanup's interface is modern, organized, and easy to use. For those who want an efficient, secure solution with features beyond the basics, this app is a great choice.

4. Nox Cleaner

Nox Cleaner is a robust and highly efficient alternative for those looking for a quick and thorough cleaning of their cell phone. With over 100 million downloads, the app is aimed at users who want to improve the performance of their device with just a few taps on the screen.

Its main attraction is the “Smart Cleaning” function, which automatically identifies unnecessary files, accumulated cache and obsolete data. In addition, it has a performance accelerator, RAM memory optimizer and even tools to cool the CPU.

Another strong point of Nox Cleaner is its privacy protection, with options to lock apps with a password and delete sensitive data. The interface is user-friendly, with large graphics and icons that make it easy to use even for those who are not familiar with technology.

5. Smart Cleaner – Clean Storage

Smart Cleaner is an iOS-only app that does a great job of freeing up space and improving your iPhone's performance. With a modern, easy-to-use look, it quickly scans to identify duplicate photos, forgotten screenshots, large videos, and duplicate contacts.

The app groups similar photos together, allowing users to choose which ones to keep and which ones to delete. It also has features for clearing cache and temporary files that accumulate over time. All this without compromising important data stored on the device.

For those looking for a practical way to keep their iPhone optimized without needing any technical knowledge, Smart Cleaner is an excellent choice. Its focus on cleaning up media and duplicate data makes it especially useful for those who take a lot of photos and videos.

These five apps offer complete and free solutions for those who want to give their phone a real clean, whether it’s Android or iOS.
