Ask Lemmy

Right now, it's Calibre because I just got a Kobo eBook reader and it's so great to be able to install pretty much any format of book onto my device and convert it if it's a format the device can't use. And even convert it if the book works better in a different format.

PlantNet

It identifies the species of the plant in a given photo.

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

There are some excellent apps already listed that I won't repeat, but I'll add FFmpeg. Not sure it's quite what you're after, but it's incredible.

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.

Organic Maps. After switching to graphene, I quickly found plenty of apps replacing the "defaults" I had on stock android, however, a good app for maps was impossible to find until I stumbled over that one. Great UI, local maps, even has a navigation feature. Completely replaces google maps for me.

Retroarch.

God awful complexity but once you figure out how it all works it’s incredible.

LocalSend, Immich, Signal, Aurora store, Radio Garden, Gray Jay, yt-dlp, and Bitwarden just to name a few

I still can't get used to calling programs apps

May be a bit out there, but on Android, Shattered Pixel Dungeon is a rogue lite game that is free and extremely fun to play. No ads, not very demanding on your phone, still gets updates, and easy to pick up and play when you're out traveling.

Its a very hard game, where knowledge is very important, as well as experimentation.

Emacs

Librewolf, FFmpeg, Vim, Wine

OnlyOffice. Great office suite. Also any app from FUTO

Pretty much every major open source project at this point. I need to start looking into donating to the programs I use the most.

Photopea Fully functional Photoshop in your browser. Amazing.

and Audacity

VSCode. I don't get why Microsoft hasn't monetized it but I'm glad it is free. Has so many extensions and gets great updates, even if I don't understand half of the stuff in their patch notes when I open up the program.

Another one is a little program called Stacher that basically serves as GUI for yt-dlp. It's a very pretty one though! And all the settings and buttons are super great. I'm not very good with CLI stuff so I'm glad it exists for free, saves so much time.

Libby ebook reader/browser

Lichess :) (FOSS Chess server, no account needed to play, second biggest chess server overall)

The folks behind it are one of my admirations

I dislike the implication that the most useful apps are not free.

I always feel more comfortable using FOSS software, even if it doesn't look as nice as the commercial option.

Apples
Edit: I steal my neighbours apples

It depends on how you define "app" and "free". But for free (as in beer) smartphone apps I really like.

• tidy
• Librera Reader
• these pre-packaged apks for the onnx text to speech engine which uses the piper voices that can be used in conjunction with the above Librera Reader to turn any compatible text doc to an audio book.

KiCad. It's an electronics design tool on par with commercial options in the industry, which cost a ton of money. Ever since the UI facelift it got a few years ago, it has become my go-to option. They are even working on integrating circuit simulation and finite element analysis, which is just crazy.

I miss when apps were specific to phones and we kept desktop computers out of it.

Quite a few of my favorites have already been mentioned, so I'll add some that live on my toolbar:

Zim, a desktop wiki with markdown and a lot of plugins. Great for organizing all of your notes with links and a fast search function.

Heroic launcher, for organizing your Epic, GOG and Prime collection.

Geany, an extremely configurable and light editor that can be as simple or as full featured as you want, via plugins.

Terminator, a solid multi terminal emulator where I spend most of my time at work.
