From the main menu in One Booster, you can see the five main features: cleaning, phone optimization, battery-saver mode, the security tool and the CPU cooler. You can use any of these five features with just a tap. All you have to do is tap on any of them, and the app will instantly start working.
The cleaning tool will scan your device looking for obsolete files or junk that you can delete. Nothing will be automatically deleted, of course. But it will show you exactly what it found and ask you if you want to proceed with the file deletion. Like this, you can be sure not to eliminate anything important when trying to save space.
The battery-saving mode, like most tools of this kind, will 'kill' any background processes on your Android, so they don't unnecessarily drain your battery life. This is similar to the CPU cooler, which will detect the most demanding apps and close them.
The security tool will simply analyze all your installed apps and look for any suspicious files. It is normal for this search to come back without any results, as your devices usually won't be infected... Although you never can be sure.
One Booster is an interesting app that might be particularly useful for those who have medium to low-range devices. What's more, the app size is pretty small (less than 30MB), so almost any user can install it effortlessly on their Android.
