Linux

Because you asked about "apps", people are replying with mobile apps. I think you wanted to write "programs" considering the community. Maybe you should edit this

Logseq.

• LibreWolf as my browser (it's a more secure and private version of Firefox, comes with a pre-installed adblocker and removes all the unnecessary junk) (Flatpak) with some of the following extensions:
  • LibRedirect for redirecting privacy-invasive websites to private frontends
  • ff2mpv
  • Read Aloud (text-to-speech)
  • Buster for solving CAPTCHAs
  • Dark Reader

  • Server-Status (GitHub) shows information about a web server like country/region (via local GeoIP database lookup), SSL certificate information and more. Good open source alternative to Flagfox.
• Thunderbird for emails (Flatpak)
• Proton Mail Bridge (Flatpak)
• Merkuro Calendar
• Ptyxis (Flatpak) as my terminal. It's optimized for containers (e.g. distrobox). foot is a pretty good alternative if you want something more minimalistic and don't care about containers. There are countless other good options like Kitty, Alacritty, Konsole, WezTerm and many others.
• Emacs as my IDE
• KWrite, Kate or NotepadQQ for quickly editing text documents. There's also Apostrophe for GNOME.

• LMMS and Ardour for music production
• Virtual Machine Manager for creating/managing KVM/QEMU VMs (Boxes for GNOME)
• Nextcloud Desktop for connecting to my home server
• Signal Desktop (Flatpak) There's also Flare for GNOME, which uses GTK instead of Electron and feels more native (Flatpak)
• Element (or NeoChat if you use KDE, Fractal for GNOME) for Matrix
• WebCord for Discord. There are some native GTK clients like Abaddon and Dissent.
• Paper Planes (Native GTK Telegram client)
• Konversation or HexChat for IRC (Polari on GNOME)
• Tokodon as my Mastodon client

• LocalSend for sharing files on the local network (basically works like AirDrop) (also works over NetBird or Tailscale btw)
• NetBird for creating a flat VPN network between my devices

• fzf
• zoxide
• yt-dlp
• streamlink
• ncmpcpp
• ncspot
• newsboat

I don't know about you specifically, but I'm surprised how many people haven't heard of Krita, a FOSS image editing app with an optional AI Image Generation plugin.

EDIT: realized this was for desktop, so removed the original list of mostly android apps. Here's my go to desktop apps:

Lollypop - music player
Invoiceninja - open source invoicing service
Meld - file/folder comparison
Librewolf - hardened Firefox
Joplin - notes
QEMU/Virt-Manager - virtualization for that one windows app you still need
KeepassXC - password management
Element-desktop - Matrix client
Gparted - no fuss partition management
Lutris - game launcher that works with epic games (among many others)
PDFarranger - best PDF management I've found on Linux Soundconverter - easy to use file converter
Restic - backups
Fdupes - duplicate file finder
Freetube - privacy respecting YouTube client
Paperless-ngx - very well built electronic document storage. Must be run as a server.

They are called "programs", not "apps". The word "app" was created for the iPhone and originally meant a "mini" slimmed down application meant for mobile devices, not a catch-all term for any user program running on a CPU.

Emacs.

Emacs is an app platform in and of itself, and the vanilla installation comes with dozens of its own apps pre-installed. Like how web apps are all programmed in JavaScript, Emacs apps are all programmed in Lisp. All Emacs apps are scriptable and composable in Lisp. Unlike on the web, Emacs encourages you to script your apps to automate things yourself.

Emacs apps are all text based, so they all work equally well in both the GUI and the terminal.

Emacs comes with the following apps pre-installed:

• a text editor for both prose and computer code
• note taking and organizer called Org-mode (sort of like Obsidian, or Logseq)
• a file browser and batch file renamer called Dired
• a CLI console and terminal emulator
• a terminal multiplexer (sort-of like "Tmux")
• a process manager (sort-of like "Htop")
• a simple HTML-only web browser
• man-page and info page browser
• a wrapper around the Grep and Find CLI tools
• a wrapper around SSH called "Tramp"
• e-mail client
• IRC client
• revion control system, including a Git porcelain called "Magit"
• a "diff" tool
• ASCII art drawing program
• keystroke recorder and playback

Some apps that I install into Emacs include:

• "Mastodon.el" Mastodon client
• "Elfeed" RSS feed reader
• "consult" app launcher (sort-of like "Dmenu")

Syncthing and KeepassXC for syncing 2FA between devices. (I use Bitwarden for passwords)

Linux, system:

• KDE Plasma (Dolphin, Kate, Kfind, Merkuro, shell, Spectacle)
• Librewolf / hardened Firefox (system app because of user namespaces, which Flatpaks cant create)

Linux, Flatpak:

• syncthingy
• thunderbird
• libreoffice
• KDE: Okular, Gwenview, maybe soon digiKam
• Qt: qBittorrent, Keepassxc
• GNOME/Circle: Celluloid, PDF Arranger, Carburetor, Decoder, G4music, Railway, SimpleScan (or Skanlite), Impression, GIMP
• GTK: localsend, GPU Screen recorder
• Electron: Freetube, Signal, Cryptomator, Nextcloud
• Podman: StirlingPDF

Android:

• Fossify Gallery, Calendar
• Material Files
• Markor
• Antennapod
• Florisboard (or maybe Futo, but I dont need the fancy stuff yet)
• Shelter
• localsend
• Obtainium
• dict.cc
• Grayjay
• k9mail
• soundbound (spotify), seal (ytdl)
• öffi, kleine Wettervorschau
• SaveTo...
• mjpdf

An web browser. 99 percent of my mobile activities are done in Firefox. I have Organic Maps for routing, a local mobile payment app and a local sharing electric sooter app.

This is pretty much all apps I use.

Analogous to the Krita post, I am surprised nobody seems to know KolourPaint. It's similar to MS paint. I use it, when I need to make a quick sketch, whiteboard style, e.g. when sharing my screen with a coworker.

Otherwise, I really must have Dolphin and Okular.

I love dolphin's split mode (quickly toggled with F3) and its ability to seamlessly navigate all kinds of protocols for my NAS, webdav for nextcloud storage, MTP for the phone...

Okular has annotations which have been super useful to me. And it's so easy to switch between viewing single page, two-page and multi-page. Which is great for skimming text documents and presentations. The auto reload ability is great when iterating on a document (e.g. latex doc or matplotlib chart).

Otherwise, of course firefox and thunderbird, not much to say here Please don't use chrome. It's market share makes Google the de-facto owner of www technology. But I guess I'd be preaching to the choir here.

I use CoreCtrl to fix my GPU's atrocious fan curve, which is a necessity since normally it overheats to high hell. With CoreCtrl, I have a nice fan curve that makes my GPU rarely, if ever, run hotter than 70°C.

oxipng, pngquant and svgcleaner for optimizing images

auto-editor for removing silent portions from video recordings

Thrown away your current ssh client and get

https://xpipe.io/

I use XSane and TheGimp to scan and edit my paintings, Firefox with privacy extensions to browse, VLC to play videos, Gnome Mahjongg to waste time playing. I used to use Resolve to edit videos, I'll soon start using Kdenlive. As a visual artist I have a thing for film emulation that Kdenlive can't do, but it's something I'll have to leave behind.

BleachBit is a must have and PhotoGIMP is pretty neat.

A good kit IMO, in order of priority:

• Cherrytree; nominally for making hierarchical lists but you can basically use it as a wiki for your entire life. You can theme it yourself too, if you think it looks too retro out of the box.
• Syncthing, for keeping files synced between devices without having to use a server.
• Qbittorrent, for getting files you need. Remember to install search plugins.
• KeepassXC. Password manager (local, not on a server, use in combination with Syncthing).
• Convertall, for unit conversions.
• Calibre, for managing an ebook library, converting formats, removing DRM, transferring to ereader etc.
• Rhythmbox, for music library, podcasts, internet radio.
• Shotwell, for photo and video library. Easy to use, supports tags (metadata written to image files).
• GIMP, for image manipulation. It's extremely versatile, comprehensive and versatile. 3.0 is due out soon and will include non-destructive layer effects. Heavyweight piece of software, so expect a learning curve.
• Ardour, for music production. Heavyweight, steep learning curve.
• Flowblade for video production. Lightweight, easy to learn.
• Libreoffice, desktop publishing.
• Librewolf; privacy-focussed web browser.
• Thunderbird; highly organisable email client.
• Freetube, for watching youtube videos without all the ads and tracking. Local subscriptions and playlists, which you can export to use with Newpipe on Android. Also lets you download video and audio.

If you like the terminal also add:

• ranger; file manager
• newsboat; RSS feed reader
• yt-dl; download videos from youtube and many other sites ;)
• w3m; command line web browser. I like to use this in combination with newsboat.

Enjoy!

edir to mass-rename

fd is more convenient than find

aria2 makes downloads go brr with parameters -x 10 -k 5M and is integrated with multiple tools like yt-tlp, yay

Oh, and pass for password-management

ssu makes root console tools password-less. That and rdo for gui-tools (both a bit over 100 loc) made me uninstall sudo.

The first things I install on a fresh linux install are always htop (task manager) and micro (nano but better).

There's no doubt there are a great variety of Linux packages in use.

Recently I did a CD install of Debian 12 (Bookworm) desktop with Gnome, which loads a bunch of stuff over the Net. Here are extra packages that I installed manually. The first set is used by and with an automated configuration script that I wrote, so they have to come in to begin with.

Here are third-party packages I admire. These are not available in Debian repositories although some provide Debian-compatible repositories of their own.

Tor Browser Bundle: Anonymizing Network Browser

This is available from https://dist.torproject.org/torbrowser/ as a tarball. This should be unpacked and the whole tor-browser_en-US directory moved to the ~user folder. This is so that the browser can auto-update at user authority as the need arises.

RetroShare: Secure Communications with Friends

This has its own Debian-compatible repository.

metar: A Package to Parse METAR Coded Weather Reports

~/lab_pip/bin/activate
pip install metar --upgrade

weeWX: Open source software for backyard weather stations.

From http://weewx.com/docs/debian.htm. Although a Debian package exists, doing any development practically requires that all the code be in user-space, so don't install the package. Download it instead.

OpenHAB: Home Automation

This has its own Debian-compatible repository.

Ant: GTK3/4 Themes by eliverlara

From https://www.gnome-look.org/browse?cat=135&ord=latest.

This is for claws-mail. It provides better contrast.

Not necessarily unheard of but Floorp has been pretty great for work. I think all of the other applications I use are well known within their respective niche (e.g JOSM)

Localsend, distrobox+podman and ublock origin just to name a few
