Android

Considering "top" as meant to be "most used", I'd say:

• Voyager, which I'm using right now, a Lemmy client.
• Tusky: a Mastodon client.
• Mull: Firefox fork.
• Firefox (yeah, I have two Firefox installations)
• Sketchbook: a drawing app, I even paid for the additional features.
• Google translate: when I don't remember how to say something specific in English, or when I want to experiment with multiple languages, especially Latin (and Google translate is the only translator app to have Latin support)
• Noto (I was previously using Notesnook): text editor with folder capabilities. I use it to write poetry, free from distractions
• Acode: source code text editor. I use it to create Node.js snippets which I run with...
• Termux: a kind of a "Linux emulator", it emulates a terminal environment within Android with additional programs compiled to arm architecture. One of those programs is Node.js (both the REPL, the runtime and the npm package manager)

My "Top" apps are what I think are cool, not necessary what the most useful apps are to me.

Briar its a peer to peer communications app that can communicate via wifi, blutooth, or through the internet via Tor. It can form a sort of mesh network with devices in proximity. Hypothetically, with enough users, you could spread information across a long distsnce even with a nationwide shutdown of the internet like some authoritarian countries do.

There's already some public forums on there by connecting to random people around the world via Tor, although, these forums doesn't have much activity now. But it exists and thats so cool. Its like a secret corner of the internet, even more obscure than the "dark web"

Wasted Remember those news about iPhones randomly restarting in police storage lockers? This app does something even better. Amongst many functions, this app can let you set your phone to auto-wipe itself if not unlocked for X amount of time, ranging from 5 minutes to 7 days. (Warning: You may get in legal trouble for using this, if you get arrested and the phone auto-wipes, you could get a "Destruction of Evidence" charge. I am not a lawyer. You might wanna consult a lawyer before using this)

OpenKeychain Just a PGP tool for Android, pretty straightforward. Very cool to have a digital signature right in your pocket to validate your online identity with other internet users. Potentially useful for ~~secret drug trades~~ ahem just kidding lol, don't do drugs, kids. (Seriously, don't)

I use Android as my secondary phone, my primary is an iPhone. Though for the past six months, my use of Android has surpassed iOS as the latter is now only for calls, messages and reading emails. For replying to emails, I use a computer.

I have removed as many Google apps as I could using Canta, as long as the phone is able to boot and function.

The apps, in no particular order (read: the order in which I can recollect):

I haven't seen anyone mention Gboard yet so I'll say Gboard. Best keyboard on Android.

If I had to pick some of my favorites:

• BuzzKill, Gives you total control over your notifications. I use it to auto clear apps that think they need to have a persistent notification like VPNs, Smart Watches, etc.
• DuckDuckGo, For their very useful, (In my opinion) app tracking protection proxy that they have built into the app.
• GAMEYE, For tracking my physical games collection and my extensive Amiibo collection.
• Grayjay & Revanced , For when I want to watch YouTube on mobile.
• Image Toolbox, Great for doing a whole bunch of different things. Works especially well for image related tasks, but does more stuff than that too.
• LocalSend, Airdrop but cross platform and open source. Really good.
• Privacy, An app that links to your bank account and lets you make virtual cards to obfuscate your real debit card. Super useful as well for setting up with subscriptions so you can just turn the individual card off instead of having to go find the subscription cancel option for each service.
• p!n, A very simple app that adds a quick actions menu button to pin a notification. I use it to essentially add reminders and notes to my notifications real quick.
• rdx, A simple Reddit viewer for when I have to view a Reddit link for any reason. shudders
• Shortcut Maker, Super useful app for when I'm not using Niagara Launcher. Let's you make home screen app like shortcuts for a wide variety of things, including going to specific settings, launching specific sets of apps, and way more. Used to be my favorite app before I got into Niagara.
• URLCheck, Acts as a middle man after I click a link, telling me a bunch of info about it before letting me pick which browser I want to open it in.
• Niagara Launcher, my launcher of choice. Not for everyone, but I have found it makes navigating my phone super fast. I have tried so many different ones, but the fact that the app drawer is always on open on the home screen and I can navigate to each letter quickly made it the best for me.

Anyway yeah, those are some of the ones I use frequently. Sorry for not linking to them, but it would have taken forever lol.
