All-in-One Toolbox is just that: a versatile all-in-one Android booster app. AIO Toolbox follows the model of many Android cleaner apps with a quick one-tap booster that cleans up cache, background apps, and memory; it also includes extras like an app manager, file manager, and CPU cooler (which kills background apps to reduce load). A handy "Easy Swipe" brings up a radial menu to quickly access utilities from your home screen or other apps. 

Where the app does suffer a mite bit is in organization, with tools split across a vertical feed and multiple tabs. Still, it's definitely worth a download if you want to get the most out of your Android phone.

Most importantly, Files gives you ultimate control over what gets saved and what gets trashed, so you're not removing something important when you're getting rid of duplicate files, unused apps and other space eaters.

Ashampoo's an old standby when it comes to PC utilities, and the German software company has since branched out to develop mobile utility apps as well. Droid Optimizer is an all-in-one system optimization app that can be set for quick use, or for more detailed cleanup. 

A 1-Touch Speed Up mode can be set to clean the memory cache and stop background apps (with an optional whitelist), while a more selective Clean Up mode lets you go point by point. An App Manager lets you bulk uninstall apps or view permissions, while a Privacy Advisor flags apps with that have been granted permissions that might be abused for your review. There's even a handy automatic scheduling mode to automate cleanup or disable Wi-Fi at night.

Another element that could be slowing your Android phone down is the custom launcher that the phone maker has installed. If you find all the extras and doodads distracting — or worse, if you find that they actually slow your phone down — consider getting a customizable Android launcher like Nova Launcher. 

Fast, sleek and highly customizable, Nova Launcher is among the best modern Android launcher apps. Nova balances extensive appearance and utility customizations with a minimal performance impact, letting you set your home screen just right without slowing down performance. There are a lot of options to work through, from color themes to icon packs, scrollable docks to app drawer customizations, folder settings and infinite scrolling.

Magisk (Free)

If you're willing to void your warranty (and run the risk of bricking or damaging your mobile device), you can gain some neat utility by rooting your Android device. Magisk is an app that helps you do a “systemless root” of your phone, allowing you to access superuser permissions without changing your system partition as you would need to using traditional rooting methods. 

This has a bunch of benefits, including the ability to keep receiving OTA updates to your OS, as well as making it easy for you to selectively hide the rooted status of your device from apps that use Android's SafetyNet feature to detect a rooted device. (These include Netflix and many banking apps.) It's effectively the best of both worlds, though as usual, rooting does involve a certain amount of risk and voiding your device's warranty.

Tasker ($2.99)

Android also features powerful apps that can automate trivial or repetitive tasks based on a variety of triggers. Among the most famous of these is Tasker, a versatile task automation app for Android phones that lets you create your own automatic task scripts. 

From automatically silencing your phone at work, killing your mobile data when arriving at home or firing up your music app when you plug in your headphones, there are so many possible uses for Tasker that it'd be folly to attempt to describe them all. 

While Tasker works perfectly fine even without root access, installing it on a rooted phone allows you to utilize even more custom task options. You can even take some of these automatic scripts and publish them in app format with the Tasker App Factory add on.

Download Tasker: Android

IFTTT (Free)

While Tasker excels at lower level hardware and software automation, IFTTT focuses on internet and app automation based on a variety of triggers. The app allows users to create customized "recipes" or tasks built around the structure "If this, then that" (from which the app takes its name). 

For instance, you could automatically receive your favorite team's recent game score the minute ESPN posts it. IFTTT employs a wide variety of triggers and actions ranging from websites, apps and even other devices and peripherals. You can even browse through other people's trending and featured recipes, as well as themed collections and all-time favorites that you can install or modify.

3c Toolbox, formerly known as Android Tuner, provides users with a ton of diagnostic and tweaking tools that savvy users can employ to improve the health of their system. 

The toolbox includes a task manager; you can also backup or restore APKs, check on CPU governor or adjust system settings such as SD cache size. There's also a wealth of diagnostic data to view. As with any app that tinkers with system settings, be careful of what you tinker with in 3c Toolbox and do your research before changing anything.

Greenify (Free)

Greenify basically puts an app on your Android phone in a state of hibernation, where it's unable to access system resources or bandwidth or run background processes. However, Greenify allows you to run an app normally in the foreground when you explicitly select it without any extra fuss. 

If you've got memory or battery hogs that keep draining resources in the background, don't bother with a task-killer when you can just Greenify it. Just don't do that to your alarm clock or messaging app, unless you want them to stop working.
