Wikipedia. Not an app but still deserves a mention.

uBlock Origin leading the pack by at least a furlong.

OBS, and Blender. Two industry shaping software solutions that ere fully open source and free.

The Dialer.

• Comes with every phone
• 10+ digit number instantly connects you with millions of people, services, and institutions
• 3 digits connects you with life-saving emergency support
• Very low-latency voice support
• High quality audio (most of the time)
• No ads
• No obnoxious UI

All kidding aside, I’m routinely astounded at how we have yet to top the ease and utility of old-fashioned phone service.

Linux

Blender, Gimp, Inkscape, OBS (open broadcast software), Linux distros of various sorts, openHAB, LibreOffice, Firefox (and plugins like uBlock), PiHole, VirtualBox, Notepad++, Paint.NET, VLC, 7-Zip, FileZilla…

I’m sure there’s more.

Fucking entire Fedivere with No ads.

I still can’t get used to calling programs apps

New pipe, I didn’t see anyone mentioned it

Besides, I use Linux, Organic maps, Signal, VLC, KDE on daily basis and THANK YOU good people on internet for making my life happier!

Get outta here you Hedge Fund Manager! Leave our apps alone!!

Librewolf, FFmpeg, Vim, Wine

Can’t believe no one has mentioned Home Assistant. Automation engine for home and have local control over almost everything “smart” at home.

Home Assistant, not only an App but it changed the way i look at IoT/Smarthome and in that way it brings me a lot of comfort.

Libre Office

Proton. Literally makes any of the big linuxes into the streamos people are waiting for
