Maintaining system performance is essential for those who rely on technology on a daily basis. Fortunately, there are several apps available for Android and iOS that help you identify performance bottlenecks, excessive memory consumption, abnormal CPU usage, and even network issues. And best of all, they all come with a free trial, so you can try them out before deciding whether they're worth keeping.

Below, you'll find five great apps that show you if your system is overloaded and offer useful tools for optimizing and monitoring performance.

CPU-Z

CPU-Z is a lightweight and powerful app that provides detailed insight into your device's components. It's ideal for anyone who wants to know if their processor is overloaded, their memory is maxed out, or their temperature is abnormal.

With a free trial, the app displays real-time data on CPU, GPU, RAM, storage, and sensors. It's especially useful for users who play games, use heavy apps, or want to monitor their phone in critical situations. The interface is simple and straightforward, with well-organized tabs that allow for easy navigation.

Another strength of CPU-Z is its reliability. It presents technical data accurately, without taking up too much space and without intrusive ads. If you suspect your phone is running slowly or overheating, this is a great first step to understanding what's going on.

One Booster

One Booster is geared more toward the general public who want to improve their phone's performance with one click. In addition to detecting system overload, the app offers features like cache cleaning, junk file removal, and battery saving.

During the free trial, you can use almost all features, including "Phone Booster," which analyzes CPU usage and automatically closes processes that are consuming excessive resources. There's also a temperature checker and a virus security center.

One Booster's biggest selling point is its usability. It's very easy to use, with large buttons and clearly displayed information. Ideal for those who aren't very tech-savvy but want to keep their phone running smoothly and quickly.

Fing – Wi-Fi Network Scanner

Performance issues don't always stem from the device itself—sometimes, the overload lies with the Wi-Fi network. Fing is a perfect app for diagnosing this type of situation. It displays all devices connected to your network, tests internet speed, and identifies potential interference.

The app offers a free trial of the premium version, which unlocks features like connected device history, intrusion detection, and security alerts. Even in the free version, Fing is already quite comprehensive.

With it, you can determine whether slow speeds are caused by excessive Wi-Fi connections, a poorly configured router, or an app hogging bandwidth. The interface is modern, and the app is highly recommended for homes with many connected devices.

DevCheck

DevCheck is an advanced tool for those who want to monitor all aspects of their system in real time. The app displays comprehensive statistics on CPU, GPU, RAM, storage, temperature, and sensors—all with detailed graphs and instant updates.

During the free trial, users can access all basic performance information and set up alerts for CPU overload or high temperatures. There are also customizable widgets and dashboards to monitor the system directly from the home screen.

DevCheck stands out for being technical without being complicated. The interface is attractive, with colors that make data easy to read, and the app itself performs exceptionally well. It's perfect for intermediate or advanced users who like complete control over their system.

Nox Cleaner

Nox Cleaner is a multi-functional app that works both for cleaning and detecting performance issues. It allows you to run quick tests to determine if your phone is overloaded, as well as perform deep cleaning and speed up the system with a single tap.

In the free version with a trial of premium features, the app offers CPU scanning, memory optimization, analysis of high-usage apps, and integrated antivirus. All this without requiring any technical knowledge from the user.

With an intuitive interface and well-distributed features, Nox Cleaner is great for those looking for an all-in-one solution to improve their phone's performance. Ideal for both home use and those who work with their smartphone all day.
