What (free and open-source) applications do you use on a daily basis?

mpv (video player)
Logseq (knowledge base/journal)
KISS launcher (android launcher)
OpenTracks (fitness tracking)
BreezyWeather (weather)
KDE connect (app to do shit between pc and phone)
Tasks (todo)
AntennaPod (podcasts)
Hacki (hacker news)
FlorisBoard (keyboard)
Unexpected Keyboard (another keyboard)

Logseq is fantastic. I use it every day at work now for both knowledge and also lightweight task management.
Maybe it's just a me problem, but I always have had troubles getting KDE Connect connecting my phone to other devices than my desktop. My phone and laptop could both be connected to the same wifi and be within inches of each other but refuse to acknowledge their existence. But I have my phone on the other side of the world and I swear it'll be able to connect to my desktop with no problem.

KDE Connect is a pretty good program, but I can't recommend it because of the troubles I always have.
- I had this too until I discovered my router doesn't allow communication between devices connected to the 5GHz band. 2.4GHz works fine so now I have everything connected to that
- It's ability to connect your phone to your computer is honestly awful. It would be better if they just openly popped up a window and told you to pick the IP, but they even have to hide that and not support it on every platform.
  
  My laptop's plugged in my phone's on a Wi-Fi network they're on different VLANs. They could let me search for it by DNS name. They could let me just use a couple of static IPs so when I go from home to work it could find it in either place.
  
  If you have any equipment beyond a crappy one band ap, it's just going to fight you every time you want to use it.
  
  I love the software, I love the plugins It's just too damn bad that You have to remember to screw with it every time you think you might want to use it.

Syncthing.

Somewhat self promoting for the first two of these items as I'm directly involved. Leaving out the more obvious ones (Linux distro etc.) as they will have been mentioned. I'll stick to some of the less known things I use.

Pulsar - a community-led fork of the discontinued Atom text editor. Lemmy community
Joplin - note taking app. Lemmy community
Halloy - IRC client built in Rust and Iced
Navi - Command line cheatsheet tool
GitUI - Terminal UI git tool
Skim - Fuzzy finder
Dust - Disk usage tool (like du)

Kudos for including some of the Lemmy communities!
Thanks for highlighting Pulsar.

I always found Atom clunky, but it was instrumental in changing how editors were made, perceived, and used.

It did not deserve the death/abandonment it got.
- Atom was my go-to editor while in school--hard to believe it's been long enough to be abandoned already. I'm going to have to check Pulsar out.
Dust has completely replaced du in my every day work. Other tools also written in Rust I make use of include Bat for an upgraded experience from cat, Tokei for quickly counting and recognising codes, and several other security tools like RustScan.

I learn about Joplin today. Thank you for sharing your list.

Vim

I even use VIM on my phone (termux).

I tried various GUI text editors on Android, but they tend to be buggy or hard to navigate. Then there's the fact that I can just open a tmux session, detach, ssh into my phone and attach it.
- I've been using vim since it was just vi and I can't even begin to think about using it on a virtual keyboard!

Termux
Holy hell. So much it can do. Right now I am using it to transcode MPEG2 videos to AV1. With CRF 25, Preset 5, with a 480p30 video I get 5fps in Termux on my older Snapdragon 860. Meanwhile my laptop's Ryzen 3 3200U does 2fps.
You can run different server applications. Some are supported natively (e.g.: Tinyproxy, Privoxy, Squid HTTP proxy, apache2, nginx, navidrome, OpenSSH, TigerVNC, rsync, xorg-server, xwayland, xrdp,...) and some can run in proot (e.g.: Jellyfin, NextCloud). If you already have some web server and want it public, there's cloudflared too, so you can access it via Cloudflare tunnel.
RTL-SDR driver
Allows connecting RTL-SDR on Android and starting RTL-TCP server.
SDR++
The best general-purpose SDR app available on Android, GNU+Linux, Windows and MacOS.
KDE Connect
Nicely connects phone with a computer. Data transfers, remote control, finding your phone, synchronizing notifications.
LibreTorrent
Great client for Android.

There's more, but those I don't use daily, or have already been mentioned.

I understood a couple of those words...
For iOS folks, a-shell and iSH can do what termux is doing on Android. Ffmpeg, most userland Linux things.

Both are open source.
- Yeah, I remember iSH being on TestFlight and just being blown away. Like what it could do on an iPhone 6S as an app.
Can you link to some tutorials to learn to do what you describe here? Specially termux all I found was a Linux terminal emulator for android
- Thats the termux they are referring to
- Install it though F-Droid, third party app store.
I have many doubts, I'll try to quote each.

I get 5fps in Termux on my older Snapdragon 860. Meanwhile my laptop's Ryzen 3 3200U does 2fps.

Is this good or bad for Termux? I'm kinda inclined to think it is good (I have a SD 865 so I'm extra curious).

(e.g.: Jellyfin, NextCloud).

I have read about the self hosting possibilities before for sure and while I will always find it amazing I would die inside if I had to use my phone (and specifically Termux, since I think text selection, copy/paste and overall typing is bad on it), that without proper hardware ofc (like external mouse and keyboard... Or a UI like DeX) so I gotta ask, do you use any of those services? If yes do you have some of those tools I just mentioned?

RTL-SDR driver
Allows connecting RTL-SDR on Android and starting RTL-TCP server.

I kinda want to know what you meant here.

SDR++
The best general-purpose SDR app available on Android, GNU+Linux, Windows and MacOS.

I only know SDR from the video format scene, and I know you want HDR or better.

LibreTorrent
Great client for Android.

This is cool, and I didn't know about it, but surely there are better options to use torrent on Android?

There's more, but those I don't use daily, or have already been mentioned.

I kinda want to know what more, because honestly, if Termux was paid you would almost sell it to me 🤣
- RTL-SDR is basically a way of using a digital device as a broadband radio. That is an oversimplification, but that is the idea. There are cheap USB devices out there that will turn a PC into a ham radio receiver (among a really wide range of other bands like weather satellites). I have no idea how they are doing it with Android, however. Maybe using the phone's antenna.
- I am sorry for not responding quicker, but I was at school and I am also tired, so don't expect a high quality reply.
  
  Is this good or bad for Termux? I’m kinda inclined to think it is good (I have a SD 865 so I’m extra curious).
  
  I have no idea. My phone and laptop are the 2 only pieces of hardware to test with. I also wanted to try OnWorks, but getting the file to that seems fairly painful. Downloading that particular video from archive.org is too slow, trying to get it from FileNow where I uploaded it would hang every 14MB and fail. The only working "solution" was running nginx webserver with that file there in Termux and creating Cloudflare QuickTunnel, but my mobile data is slow and we don't have internet at home. So I just didn't get to try it.

If yes do you have some of those tools I just mentioned?
  
  I have only tried Jellyfin briefly and want to try running NextCloud when I'll have time for it, as that seems more painful looking at the guides on internet. Jellyfin just didn't fit my use case, so I replaced it for nginx with fancyindex module and Material theme.
  I don't have a problem using the touchscreen. Copy-paste works pretty well, like with any other text. Just a little tip: Home puts you on start of the line and End at its end.
  But anyway, I do often use a hardware keyboard. Sort of. I don't attach it to my phone, instead I SSH into my phone from some computer, be it my laptop or school PC. For GUI I can also use VNC server. Keep in mind VNC isn't encrypted by default. There's VNC-TLS and X509, but I have no idea how to deal with certificates, which allows anyone to do MITM attack on me. Simplest solution is running it over SSH tunnel, at which point I can use unencrypted VNC which is compatible with more programs.
  
  I kinda want to know what you meant here.
  
  RTL-SDR is one of the SDRs (Software Defined Radio) that I have. I also have a clone of RSP1. I don't know where I would start on that. It allows a lot. But after all, you can just search "What to do with SDR" yourself, and find countless answers.
  My most favorite use is receiving satellite signals. So far only in the 137MHz band because I don't have a satellite dish. In this case V-Dipole is enough. Since I have the RTL-SDR Blog's extendable dipole, I can fit a satellite imagery receiving station into my pocket.
  Check [email protected]
  Example image that I received over APT (it's analog signal, old-school tech):
  
  I used noaa-apt, again in Termux, to decode it.
  Or perhaps this catches your interest: Cracking GSM phone calls and SMS with SDR (YouTube playlist) which is obviously illegal. It also only works for the weak A5/1 encryption and only with GSM (2G). While newer standards are sure safer, don't trust anything that's not E2EE at all anyway.
  
  I only know SDR from the video format scene, and I know you want HDR or better.
  
  Yep, SDR = Software Defined Radio.
  
  This is cool, and I didn’t know about it, but surely there are better options to use torrent on Android?
  
  I am not sure. LibreTorrent works well for me.
  
  I kinda want to know what more, because honestly, if Termux was paid you would almost sell it to me 🤣
  
  I meant other FOSS apps, not stuff in Termux. But it's like a locked down GNU+Linux machine, so it just does a lot of Linux things. Thanks to proot-distro or Andronix scripts you can even have Ubuntu, Arch Linux or other distros on it. That's what you need for Jellyfin for example. Just keep in mind that your phone is most likely aarch64 and Termux doesn't emulate other architectures. Though it can run QEMU 😏 (but if you tried Limbo PC Emulator x86 you understand how useless it is with anything better than Windows 98). I did get that to run Windows 7, yes, but even just opening a file browser took a few minutes.
  Anyway, cursed screenshot as a bonus:
  
  Even though it CAN be done doesn't mean you SHOULD. I already cooked 1 Poco X3 Pro motherboard to its death.

Firefox

Well, there's the usual: GIMP. Lemmy & Firefish instances. Linux OS. Syncthing. Firefox. Inkscape.

qOwnNotes is cool and I don't hear much about it.

Also shout out to libre games. GZDoom and UnCiv mostly. But MOSTLY GZDoom. GZDoom is a platform, not a game.

My kids love minetest. I play Dday, a quake 2 "ww2" total conversion mod.
- iirc the purpose of mintest itself is to be a stepping stone to make other game, but if people are having fun playing it as it is then I'm very glad
- Pretty much all I know about Minetest is "It's not Minecraft, and my friends all play Minecraft."
Wesnoth's very fun too!

NewPipe fork with SponsorBlock

Not that there's anything wrong with newpipe, just additional information:

Sponsor block is now avaliable on Firefox mobile app. It even works for YouTube videos that are embedded in other sites.
- That's good to know. It's integrated with ReVanced really well too.
- Thank you for pointing that out. I knew Firefox had updated to enable desktop add-ons to work with mobile but I didn't see Sponsor Block when I took a quick look.
Seems like it is no longer maintained. Unfortunately that means it is only a matter of time until it breaks forever.
- Looks like it's only one update behind though. That's not too bad.

Hey I use my own app every day. Let me tell you about it. :)

nephele-serve is the dedicated server version that I use to manage all my Jellyfin movies and TV shows. I also back up all my systems to it with DejaDup.

QuickDAV is the desktop app version that I use to transfer files around all of my way too many PCs, tablets, and phones (I develop mobile apps too, so I have a lot of devices). It’s easier (and usually faster) than using a USB stick, and it’s safer than leaving shares open all the time.

They’re both open source and use the same server software, Nephele, that I wrote for my email service, Port87.

Oh I’m also working on putting up a Docker image for nephele-serve and a Flatpak of QuickDAV.

And nephele-serve is now available as a Docker image! :)
why not syncthing for files?
- I’m not exactly sure what you mean, since Syncthing doesn’t do either of the things I was talking about.
  
  Syncthing is for syncing files.
  
  nephele-serve is for running a dedicated WebDAV server.
  
  QuickDAV is for transferring files.
  
  Syncthing has its own use cases, they’re just not the ones I use these apps for.

Thunderbird

Ardour is fantastic.
- Agreed! I only use it for hobby purposes but the amount you can do is staggering.

I use Aniyomi, Fennec, Obtainium, Jerboa, BetterUntis, Bitwarden, DroidFS, Aegis, LibreTorrent, Shelter, Survival Manual, Termux, ConnectBot, LocalMonero, F-Droid, RethinkDNS, InnerTune, Mastodon, Kuroba-Ex, Signal, Element, QUIK and FlorisBoard

Does anyone know of a FOSS file explorer for Android that supports network locations? Fossify file manager would be perfect but doesn't have support for network locations.

Material Files is by far the best file browser.

https://github.com/zhanghai/MaterialFiles
- Thanks, I'll check it out!
https://github.com/pgp/XFiles is what I've been using and am pretty happy about it
- Thanks, I'll take a look at that one as well.

There isn't much important proprietary software in this apartment except maybe for the firmware of the dishwasher / microwave, washing machine and additionally whatever software runs in an old car.

WebOS is OSS?
- I think so: https://en.wikipedia.org/wiki/WebOS
  
  I don't know about every component, but there is the Linux kernel and a lengthy list of open source components and licenses somewhere in the settings and manual. And you can get a busybox shell or something alike.
- There is an Open Source Edition

LunaSea

Jellyfin

Habits

Some subset of modern Linux distro - Firefox, Emacs, Git, Tmux, OpenSSH, i3, sway... Android - F-Droid stuff

Vlc

I self host:

Miniflux - RSS Reeader
Alexandrite - Lemmy Client
Invidious - Youtube frontend

Libretube

daily and both (desktop and mobile, cross-platform),

Mozilla Firefox

I use FreeCAD for both 3D printing and woodworking design.

I use Rednotebook for my personal journal, and it's mostly satisfactory.

I'm a fan of OpenSCAD for my woodworking. But I'm not, like, industrial with it. But I can get my work done.
- I never hitched horses with OpenSCAD. Do you model each board individually? What's your workflow?

Goodtime (a pomodoro app)

I started using Upscayl to upscale the AI images I make.

https://www.upscayl.org/

Habits
Tasks
Quillpad
Firefox
Bitwarden
Immich
Miniflux
Wallabag (also testing Omnivore)

I really love Onnivore, but my only issue is that RSS feeds are mixed in with the things you add to it. That being said, they’ve had a few updates that make it a lot better.

Godot

Syncthing (for obsidian notes, mostly. I know there are FOSS apps that do what obsidian does, but they just don't feel as good for my purposes).

LibreTorrent

On mobile:

Feeder (RSS reader)
K9-Mail / Thunderbird
Mull (Deblobbed and privacy oriented Firefox Mobile fork)
Catima (Loyalty card manager)
Cofi (Coffee timer)
Neo Launcher

On desktop:

Spotify-qt and Librespot

I use a bunch of other stuff as well but these are the one I truly use daily that haven't been mentioned yet.

deblobbed?
- I'll copy-paste this stackoverflow answer, because it sounds like its written by someone more knowledgeable than me.
  
  blobs are binary firmware, not distributed as source. they are necessary for certain hardware drivers to function, in whole or in part. As the source is not readily available, there are deblobbed distributions for opensource "purists".
  
  In the firefox context, there are certain non-free portions of firefox code base, namely the branding and some mozilla services integrations. Those are removed. This is more about licensing then availability of the code.

Jellyfin and findroid. Mainly findroid.

Also PipePipe (piped app for youtube) and libretube

I also play an open source version of solitaire and a game called box stacker, both are from the f droid store

And ofc, infinity for lemmy

I'm curious, what do you prefer about findroid over standard jellyfin media player? They seem to be pretty much the same minus findroid not having transcode support
- I’m curious, what do you prefer about findroid over standard jellyfin media player? They seem to be pretty much the same minus findroid not having transcode support
  
  Findroid allows for seamless downloading of media for offline playing, which is pretty useful. Also it's focus on only music makes it a bit simpler and more comfortable for me to use.

SumatraPDF
NotePad++

OpenRadio is a good one if you like radio and music in general. It has radio stations from everywhere and from almost every music style.

GNU/Linux
Web Browser
GIMP

A bazillion of undermaintained web libraries

Radarr, Sonarr, Prowlarr, Jellyseerr, Wizarr, Jellyfin, qBittorrent

Why do they all have double Rs
- Arr matey
- They're all related.

Firefox, Neovim, Tmux, Various KDE applications, Nextcloud, Wine, Signal, OpenSSH

Probably many more

Joplin

Do you sync your Joplin notes with Synching? Any tips?
- Not at the moment, but I suppose I could.

I use putty at work on a daily basis

KDE Plasma

I want to highlight a practical usecase for password management with open source tools. Keepass (gnome secrets on computers, and keepassdx on mobile) with syncthing syncing encrypted password files between the devices. Very effective so far. Passwords are synced seamlessly.

ANDROID Android

I'm having a harder time thinking of proprietary programs I use. I guess the biggest offender is mobile apps. As far my computer goes, discords flatpak is the only one coming to mind.

FairEmail

Darktable, OBS, ffmpeg.

On Smartphone : OpenKeychain, Tor Browser, SimplesTools Collection, FairMail, NewPipe, Fdroid, Organic Maps, Cake Wallet, Aegis

On PC : Emacs, Gimp, Audacity

I hope fossify tools are ready soon.

FileZilla

Shameless plug but I use Lemmy Keyboard Navigation (RES-like extension for keyboard navigation)

Emacs

ripgrep

Inkscape

Terraform.... Oh wait, Nevermind. I need to start switching to OpenTofu now.

Blender, Krita, Inkscape, OBS, vlc. Running Ubuntu Studio. Also, Resolve and REAPER.

Da Vinci Resolve?
- Yes! Not FOSS, I know. I use the Studio version. I like it very much.

LibreOffice Irfanview

Greenshot

gluetun

VPN client in a thin Docker container for multiple VPN providers, written in Go, and using OpenVPN or Wireguard, DNS over TLS, with a few proxy servers built-in.

Gluetun is great for when you want a container that should only use the network on the other side of a VPN.

Homebridge AltStore Voyager + Lemma (Lemmy clients)

Trillium notes!!! It's a really really beautiful note taking application for linux!

It runs on Linux but is webserver based, Its accessible by any device with a web browser. It has DB backups, protected notes, note organization, etc.
- Naah there's a native application as well on Linux. I run it without a webserver.

vim, perl, bash, just to name a few

Firefox
Obsidian
LMDE 6
Godot
Lutris

For android : Basically almost all app from SimpleMobileTools, a few version right before it was sold (to a company in a controversial city)

For desktop : some kde app that works both for windows and linux (I used windows for now) like Okular and FileLight (though this one isn't so much daily basis)

and for both I used LocalSend

There is a fork now
- https://github.com/FossifyOrg

Standard stuff, though very few from my phone so I will focus there. On it, atm just things like RetroArch, Firefox, Geometric Weather, Blokada, and Amaze File Manager.

I haven't done any research at all, but if anyone wants to share: does anyone know of a good FOSS grocery store list kind of app for Android? Something that might still work without internet, I don't care about synching anywhere else. Currently I use Listonic, mainly b/c I do not want to use Google Keep. There are some on F-droid so when I get time I'll look into those.

Kakoune

LinkDing for bookmarks
Memos for notes
FreshRSS for rss
homebridge to connect to IOT devices like Kasa Bulbs that aren’t on Apple’s Home service.

Shoutout to [email protected] for saving us when Liftoff went under.

(I'll avoid posting what I've already seen mentioned)

Thunder (for Lemmy)
Metro (fork of Retro Music)
Quik (SMS)
Molly (Signal fork)
Obtainium (updates Github apps)
MuPDF viewer
Standard Notes (private notes app)

Gadgetbridge for my smartband

Vorta for automatic backups of my computer https://vorta.borgbase.com/

Oh! Thank you for this!

The others have been mentioned. Not quite daily but I'll occasionally get paid to do CFD simulations.

FreeCAD, salome, openFOAM, paraview.

KiCAD. It's so good these days.

I still code most Python in IDLE. It's fine!

Various flavors of Linux and the many, many applications supporting that. Also OpenWRT. OpenOffice > Google Sheets.

I also grabbed an open-source script that would turn on a fan every time the humidity level rose high enough for a specific type of mold to grow, and move air until it dropped. That ran all day for a few years until the fan broke and I repurposed the other hardware.

Firefox, nuff said.
Organic Maps on my phone. I prioritize it for the privacy.
Jerboa for Lemmy
Ubuntu Linux, partially due to needing to run some kind of Linux for a class. Most people went with WSL, I chose to dual boot.

Nmap, Wireshark, zenmap at work.

I don't have a clue if anyone has mentioned it, but I use the non-root version of NetGuard to make sure some apps on my phone don't have wifi or mobile data access.

I also don't know if this was mentioned by someone else, but for one of my college courses, we are using thonny for python programming.

How is that different from disabling the access from android settings?
- Because with NetGuard I can use it on not just the apps that normal settings app list shows me, but also system apps that don't show up that you can't disable access to without a 3rd party tool. Since I'm not on a rooted device, I don't have a choice over things like being able in settings mode to try and disable apps like gøøg|e assistant because it doesn't show up in the apps list.

Librera (pdf reader and other formats), tuta mail (private mail), feeder (RSS reader), iceraven (Firefox fork), saver tuner (battery management), aurora store (replacement of play store), breezy-weather (for checking the weather), openBoard (Foss keyboard with spell correction)
