This article lists the best apps not available on the Play Store. Make sure to allow installation from unknown sources in your device’s Security Settings before attempting to install any of the listed apps.

1. Tachiyomi

It’s a common misconception that iOS is better catered than Android when it comes to the niche of manga-reading apps. The fact is that Android has one of the best options available – you just have to know where to look.

Tachiyomi is a great manga reader with a clean UI and plenty of customization options. You can arrange bookmarks into folders and subfolders, read in a well-optimized landscape view, and it has an excellent repository of sources to get your manga from. The app is still a work in progress, and sometimes doesn’t automatically update your library like it should, but beyond that it’s already great and it’s only going to get better.

2. Fortnite

Now that Epic have gone from a stalwart publisher to one of the biggest powerhouses in the industry, the company is keeping its most prized possessions close to its chest.

So Epic has decided to make its battle royale phenomenon Fortnite available only through the official Epic site on Android, where you need to use a QR code to download it. Bit fiddly, but hey, it’s the world’s most popular video-game and it’s free. What more do you want?

3. Viper4Android (Root-only)

For reasons unknown, the Google Play Store has deemed Viper4Android unfit for its hallowed halls (perhaps because it requires various deep-level permissions to function). This XDA Labs app lets you really dig in and fine-tune the audio capabilities of your phone, letting you tinker around with all manner of equalizers, effects, and custom drivers that you can download.

This one’s definitely for the audio enthusiasts, and less so for those who want quick-and-easy audio boosts for their phone. From Gain Control to V4A, the functions here are for those who know what they’re doing.

4. FireTube

One of the bugbears of YouTube for years now has been the inability to listen to music or videos with the screen switched off, which would save on both battery and mobile data.

Enter FireTube, an app that Google would probably much rather didn’t exist. FireTube is essentially a YouTube interface that lets you listen to any video you like without the actual video playing, then switch off your screen and keep listening. You can see why Google’s not that into it! If you want to know more, you can read our full guide on how to install and use FireTube.

6. MiXPlorer

MiXPlorer is one of the best Android file managers out there with a very neat user interface and plenty of features that should appeal to both casual and power users alike. For one, it offers tab support and a dual panel mode on big screens which helps if you’re working with several folders at once. You can also access your cloud files with up to seventeen services to select from including all the popular ones such as Google Drive, Dropbox, MEGA, and Onedrive.

MiXPlorer also supports root access for advanced operations, advanced search functions and a very customisable user interface. Overall, it’s a very well-rounded file manager you can get for free that doesn’t have ads.

7. Lucky Patcher

Lucky Patcher is an app that allows you to modify other Android apps in various ways. You’ll need a rooted device to harness all of this app’s great power. You can run several actions with this app such as removing license verification for premium apps, modifying apk files, removing Google ads, and backing up and restoring apps. It’s better to make a full backup of your apps and data before using this app as it can possibly lead to loss of data.

8. F-Droid

F-droid is the market for free and open-source Android software. Downloading the F-droid client makes it easy for you to search for and install open-source apps, and it also helps you keep track of updates on your device. It’s highly recommended for open-source enthusiasts.

9. XPosed Framework Installer

Installing a custom ROM is one way to modify your Android device, but you don’t really need to do so if you just want to modify a few things here and there. The XPosed Framework allows you to modify your existing system without going through the hassle of installing a custom ROM. It is for root-level users only, and there is a wide range of mods and tweaks that can be applied to your device, but be careful. I’d recommend making a full backup before using the Xposed Framework or its components.

10. Adaway

Adaway is a free and open-source ad blocker for Android. It was previously available on Google Play but was later removed after violating a section of the Google developer agreement. You can install it from F-droid nonetheless. Adaway requires root access to work, and it’s only available for Android 2.1 devices and above. All you need to do to try out each app is to download the apk from the links above. Don’t forget to allow installation from unknown sources, and do let us know of any other useful apps not available on the Play Store in the comments section below.
