I would’ve said Infinity for… something, but we know how that turned out. So, I’d say it ir most likely Fennec F-Droid, it is the first app I install in every device that isn’t a tablet

BitWarden.

One of the best, if not the best password manager I’ve ever used.

Recently it’s been Obtanium, basically it allows you to add apps which are hosted on GitHub/other app sources which don’t have auto updating, and have them automatically check and offer to update!

It’s been really useful for Lemmy clients (liftoff/Jerboa)/any android apps from:

GitHub

GitLab

Codeberg

F-Droid

IzzyOnDroid

Mullvad

Signal

SourceForge

SourceHut

APKMirror (Track-Only) APKPure

Third Party F-Droid Repos

Jenkins Jobs

Steam

Telegram App

VLC

Neutron Code

“HTML” (Fallback)

Termux

This app alone is one of the huge reasons why I prefer Android. I love that I can natively run a bunch of Linux utilities directly on my phone and use it like I would a regular computer. Everything from Vim, Python, and various networking utilities, I’ve played around with so many different tools which has helped expand my skillset over the years.

I also use the Termux-X11 addon to have a full xfce desktop environment running on an external monitor with HDMI out over USB-C.

Phones are quite capable devices and using tools like these really unlocks their full potential.

is Tachiyomi open source? if it is, then that. It’s always one of the first things I install on my device.

There’s just no better manga/comic reader app on Android (even on PC tbh).

The only thing better than Tachiyomi is one of its forks like TachiyomiSY which I’m currently using.
