Software - Smartphone

I use an Android phone.

Launcher

I use Niagra Launcher with Charcoal Flatcon Icon Pack. I have been a fan of list-based launchers ever since using OLauncher. Nothing irks me immensely more than seeing tens of icons in my app drawer and visually searching for the icon I have to click on. Why everyone doesn't use list-based launchers: I have no idea. I introduced some of my family members to text-based launchers: some didn't like it from the very start, and others haven't looked back ever since.
I have Niagra's pro plan, and it is one of the most affordable plans out there, with regional pricing (I am from a third-world country).

KDE Connect

On my most favorite apps of time is KDE Connect. Apps like these, at least for me, put the walled garden of the apple ecosystem to shame. I can literally be watching a video or listening to music on any of my devices, and it would automatically pause if I get a call on my phone. I can copy a URL on my tablet and paste it on my laptop. I can be listening to a podcast on my phone and have it automatically show up on my laptop to with all controls.

Wallpapers

My partner has a pinterest board in which she saves the wallpapers she likes. Occasionally, I run a pinterest downloader tool to download the entire board, and then use upscayl to upscale the images, and then use Wallpaper Changer to change my wallpaper daily based on those images.
