Readers often ask what our essential Ubuntu apps are so, rather than reply in the comments, I figured I’d write a list of what are, for us, must-have apps for Ubuntu. 

Regardless of whether you’re new to Ubuntu or a recent convert from Microsoft Windows, you will find lots of useful software in this list of the best Ubuntu apps. Feel free to use the comments to share your best Linux apps.

This list could be doubt the length and still barely scratch the breadth of variety and divergence that exists within the Linux app ecosystem.

Now, for the purposes of this list we will not list any software that ships by default on Ubuntu, e.g., Firefox, LibreOffice, Thunderbird, Transmission, etc and, where possible, favours software that you won’t need to add a PPA for.

1. Geary E-mail Client

Geary 0.11 on Ubuntu 16.04

Geary is an open-source desktop e-mail client with a broad set of features, a handy set-up wizard, and integrated with the Unity desktop. If you’re more familiar with Gmail than, say, Outlook then you’ll find Geary is easier to use than Thunderbird, the default Ubuntu e-mail app.

Click to Install Geary from Ubuntu Software

Other alternatives: WMail (Electron); Evolution; Claws Mail.

2. Google Chrome Browser


The Mozilla Firefox web-browser already installed on your Ubuntu system and for most it does its job, and does it well. But if you’re more of a Google user, or used Chrome on Windows, then you’ll be pleased to know that you can continue to use it on Ubuntu.

Along with built-in (and up-to-date) Flash player for Linux you can also sign in with your Google account you can sync your bookmarks, extensions and apps between Linux and other operating systems you use.

Download Google Chrome for Linux

Other alternatives: Vivaldi (Chromium) ; GNOME Web (GTK); QupZilla (Qt).

3. The GIMP Photo Editor


The GIMP, whose name is an acronym for the ‘GNU Image Manipulation Programme’, is a free, open-source Photoshop alternative. While it lacks some of Adobe’s fancier flourishes The GIMP more than matches it on the common features, and in some areas even beats it!

Whether you want to quickly autotune a selfie avatar, create a majestic multi-layered meme to share online, or do some serious pro-touch up work as part of your photographic hobby, be sure to check out The GIMP.

Click to install The GIMP from Ubuntu Software

Alternatives: Photomatix (Paid); Pinta (GTK); Shotwell (GTK). 

4. VLC Media Player


You don’t need me to tell you what VLC is as, like Firefox, LibreOffice and The GIMP, it’s arguably one of the most famous pieces of open source software on the planet!

A versatile desktop media player that can handle almost any media format you throw at it, play DVDs, and even transcode video from one format to another.

Click to install VLC from Ubuntu Software

Alternatives: SMPlayer (Qt).

5. Unity Tweak Tool Utility

The swiss-army knife of the Ubuntu Unity desktop, Unity Tweak Tool lets you fine-tune and tailor the desktop to suit your tastes. Whether you want to try a trendy new GTK theme, swap icon set, adjust the size behaviour of application menus, set up hot corners, reduce the size of the Unity Launcher… The list goes on!

From advanced configuration options to common ones: if something is adjustable chances are Unity Tweak Tool has a toggle for it!

Click to install Unity Tweak from Ubuntu Software

6. Caffeine Lock Screen Inhibitor


This app is indispensable for me. See, my password is the length of a small novella, and any time I move away from my Ubuntu machine for more than a few minutes the Ubuntu lock screen (quite rightly) kicks in.

But sometimes it kicks in while I’m in the middle of reading a length BuzzFeed article, or watching a YouTube video. In these situations I don’t want the lock-screen to interrupt me so I use caffeine.

Caffeine offers up a fast way to inhibit (block) the screensaver or lock-screen. Simply enable it when you want it, disable it when you don’t!

Click to install Caffeine from Ubuntu Software

7. KdenLive Video Editor

the kdenlive non-linear video editor

Need to trim a video clip before you upload it to YouTube? Want to work on a length video podcast with neat transitions and cool effects? Then you’ll want — seriously — to use Kdenlive.

Kdenlive is a non-linear video editor that really excels at being both easy to use and reliable to use (other Linux video editors can be crash prone).

Click to install Kdenlive from Ubuntu Software

Alternatives: Flowblade; Shotcut; Lightworks. 

8. Dropbox Cloud Storage


Dropbox provides an official Linux client that integrates with the Ubuntu desktop superbly, letting you quickly selectively sync files to and from their service, back-up new files instantly, and more.

Don’t use Dropbox? You can use Google Drive on Ubuntu out of the box on Ubuntu 16.04 LTS and later.

Visit the Dropbox Website

9. Franz Messaging Client

franz chat app

The days of multi-protocol instant messengers are long gone, with (mostly) proprietary mobile-first services now ruling the roost.

Want to chat on WhatsApp, Facebook Messenger, Telegram or another well-known messaging service on Ubuntu, without using your browser? Try Franz.

Franz lets you connect to a huge array of services, and offers some basic desktop integration.

Visit the Franz Messenger Website

10. Etcher USB Image Writer

etcher image writer

If you regularly try out new Linux distributions you’ll know the importance of having a reliable, easy-to-use image writer — and Etcher is just that.

It’s an entirely open source app and is developed by the folks at Its simple interface walks you through the process of writing an ISO or IMG file to USB or SD card.

You cand download the latest Linux build of the app from the official Etcher website:

Download Etcher for Linux

11. Atom Text Editor


Althought not the only text editor of choice on Linux (there are many, many of ’em) Github’s Atom is by far one of the more popular.

An open source text editor, Atom enables to you customize almost every feature of it, either by hand, yourself, or by installing packages, plugins and themes created by other Atom users.

You can install the very latest release of Atom text editor as a Snap package:

Install Atom from Ubuntu Software

12. Steam Linux Gaming

Steam for Linux running on Ubuntu

If you plan to game at all on your Linux machine it’ll be well worth going through the huff and puff of installing Steam, the hugely/insanely/massively popular games distribution platform.

Over 3,000 Steam games are available for Linux, including big-name titles like Tomb Raider, Deus Ex: Mankind Divided, and Total War: WARHAMMER. There’s also a huge selection of indie gems, retro titles, and independent games worth mining around for.

See our how-to for a full Steam for Linux install guide.

13. NeoFetch System Information Tool

neofetch running in GNOME terminal on Ubuntu 16.04

Looking for a fancy way to learn what window manager, GTK theme, desktop environment, kernel and bash version  you’re running? You could click through a glut of menus to find out, or you could run one command: neofetch.

First things first: you’ll need to install the app before you can run it and to do that you’ll need to grab the latest release from the NeoFetch Github page. If you’d rather use a PPA, there is one. See our earlier post for full details on how to add it and help ensure you’re always running the very latest version of the tool.

Download NeoFetch from Github

14. Corebird Linux Twitter Client


Linux Twitter users looking to use something other than their browser for catching up on the ‘what’s happening’ have a number of desktop Twitter clients to choose from, but by far and away the best Linux Twitter app is Corebird.

Corebird supports multiple Twitter accounts, desktop notifications, support for most of twitter’s features 9including quote retweets, unlimited direct messages, etc) and has a clear, clean,  and easy-to-use interface.

A few innovative features are also tucked up under its wing, including the ability to quickly enter common phrases, auto-saving of tweets in the composer box, and (mercifully) the ability to mute specific accounts or words.

Click to install Corebird from Ubuntu Software

Alternatives: Anatine (Electron); Choqok (Qt);TweetDeck (web).

15. Ubuntu Cleaner System Maintenance Tool

ubuntu cleaner

Although the open-source BleachBit typically gets our ‘system cruft cleaner’ recommendation the user-friendly (and less potentially destructive) nature of Ubuntu Cleaner just edges it out.

Ubuntu Cleaner is a fork of the ‘Cleaner’ section of the abandoned Ubuntu Tweak app. Using the app is a great way to help free up space on Ubuntu. It can remove unneeded packages, clean up stale application configs, and clea apt and web-browser caches.

See our recent post for more details.

16. FeedReader RSS Reader


I keep tabs on hundreds of apps, web sites, and other  development projects in two ways: e-mail (via mailing lists) and RSS feeds (via Feedly). If you use the latter (or even if you don’t) you may be interested in checking our FeedReader.

FeedReader is a GTK desktop RSS reader app for Linux desktops. It’s not fully polished around the edges, and has more than a couple of quirks, but it’s the next-best thing to using Feedly in a browser tab.

FeedReader is available to install on Ubuntu 16.04 LTS (only) from its dedicated stable PPA.

17. Weather Indicator Weather Tool

Keeping an eye on the conditions outside is part and parcel of our daily routine. But when you want to know a little bit more about what the weather is going to do over the next few days you can’t just “look outside” and guess.

That’s where applications like Weather Indicator come in to play. Discreet, panel-based applets that reliable inform you of the current conditions and, with a click, tell you more about what’s in store.

A variety of different weather indicators exist, many of which we’ve covered on this site.

18. Shutter Screenshot & Annotation Tool

For taking desktop, app or web screenshots and annoying them with text, arrows and icons, you’ll want to use Shutter. Nothing else comes close to it in terms of feature set and performance. Shutter does more than just take screenshots, and is able to auto-upload snaps taken to a remote web services, including Imgur.

Install Shutter from Ubuntu Software

19. Unity Folders Launcher Organisation

Unity Folders is an aptly named app that lets you create clickable folders on the Unity launcher.

Ideal if you want to organise your most used apps based on type (‘games’, ‘office’, ‘social‘, etc) without opening the Unity Dash.  You can customise folder icons (or auto-generate one based on the applications inside), while existing folders can be edited, rearranged, rename and re-other stuff, too.

20. Clementine Music Player


When I started this list I was convinced that I wasn’t going to list any music player alternative to Rhythmbox simply because few players offer anything massively different to its or its feature set.

Install Clementine from Ubuntu Software

21. Go For It Task Manager

go for it to do list app

Ubuntu doesn’t ship with a decent notes app anymore (it used to include Tomboy, but that app and the word decent don’t belong together) but it’s hard to get organised without one.

The real selling point of Go For It! over, say, Simplenote for Linux, is its simplicity. GFI is not trying to help you structure your dissertation, simply help you remind yourself that you need to start on it!

A built-in alarm feature and support for loading a custom todo.txt so you can sync your to-do list between apps and devices, make GFI an app well worth looking into.

Other Essential Apps You Should Check Out

Like I said at the start: this list could easily be 101 Must-Have Linux apps. You’ll notice I tried to (mostly) avoid CLI based tools in this list (they’d make a great article on their own right) but a few I can’t resist shouting out include ncdu; rainbowstream; and sudocabulary.

Peek is a great animated GIF screen recorder. GNOME-Twitch is a great desktop app for Linux; Wundertux is an electron-based Wunderlist app for Linux; and Rambox, similar to Franz in the list above, is an open-source all-in-one messaging app.
