Suggestions for apps

Wilflower

Hi!
I would appreciate it if you could recommend the following programs to:

packing/unpacking files
'replacement' for spootify (spotube unfortunately doesn't work for me; the program doesn't read my spootify profile. If I manage to schynchronize the spootify profile with spotube, the songs do not coincide with the original ones, and spootify tells me to change the password every time),
Youtubemusic alternatives don't interest me,
website/program for sending files.
I tested nextcloud, localshare, snapdrop, wormhole - do you know any other worth recommending?
an application showing nearby WiFi, and devices connected to the network - will they find something like this at all?
IP checker

I will be grateful for recommendations.
Best regards!

Wilflower let's go through the points.

What exactly do you mean here? Are we talking about compression or archives? There's a difference between these.
I think there hardly will be a good replacement for Spotify. I despise their business practices and use Apple Music instead. Luckily, they built a really solid Android app.
Sending files is always tricky. For the smaller transfers I use a self hosted Snapdrop instance, the rest gets uploaded to my Nextcloud and is shared via link if someone needs something huge. That combination has been pretty solid for me and I haven't heard about better alternatives.
There's of course Wi-Fi scanners, that can scan for surrounding SSIDs and the channels they use. Anything beyond that is technically possible, but would require you to brute force their WPA/2/3 passwords, which is illegal in every country I know of. You can't see which devices are connected to a certain Wi-Fi AP for good reason.
IP checker means what? Do you just want to know your public IP? Just use any website. Installing an app just for that is unnecessary and counterproductive in terms of security.

Compression tool like for example winrar,
Unfortunately, Spootify collects too much data and is not recommended,
4.I'm looking for a program with which I will be able to check who is connecting to my wifi network. Unfortunately, often a lot of people use it, so I would like to know if later the password is not shared with other people who connect to my wifi without my knowledge.
5.In this case, it is indeed better to use dedicated website for this ;)

Thank u for reply!

There's unfortunately, in terms of FOSS apps, not really many options for too many formats. I personally use Material Files which is my file manager of choice and can compress to 7z, tar.xz and regular zip (including passwort protection). I hope that should suffice.
That's the nature of Spotify unfortunately. I only know of Spotube as a replacement (at least one that is actively maintained), but since that doesn't work for you, I can't recommend anything else (besides switching to a different service).
What you're looking for is difficult to find. I would usually recommend nmap (the gold standard of port & network scanners), but for most of these types of scans you're looking for, root privileges are required. You can actually install nmap through Termux and run a local scan with nmap 192.168.x.x/24 (check your CIDR for the correct gateway) and it will return a list of the hosts on your network. The (probably) easier solution, would be to check your Wi-Fi interface. Maybe even create a shortcut/bookmark in your browser and add it to your home screen. That way you just need to log in and will see a list of currently connected devices.
It really is ^^

I found something like "ZipXtract FD" on F-droid so far it works well - I'm still testing.
It's time to go back to the offline player and upload own favorite songs like in the old days ;D
nmap looks promise and I will definitely test the program.
I saw termux on f-droid. Do you think it can be helpful (somehow) of checking who is connecting to my wifi?

Thanks a lot for your help!

Wilflower 1. I saw that app too, but so far it's not meeting my criteria (has non-FOSS dependencies) and has less supported compression formats. But if it works for you, that's great news!

A lot of my music listening is now exactly that - songs that I own. Mostly streamed via my own JellyFin instance.
Yep, it is a very powerful tool. In fact, it is so powerful, that you should only EVER scan your own network with it. Don't use it on foreign networks or domains you don't own. Also check local laws and regulations as in some regions of the world the mere possession of nmap can constitute a criminal offense. Termux by itself is a terminal emulator and supports a very wide range of programs. If you're familiar with the command line or Linux (or both), you will feel right at home. Since it works with apt, a lot of Linux programs were ported over (such as nmap). If you're looking for Wi-Fi security, you should definitely set up a guest network (every modern router supports this) and only let people outside of your household connect to that. It can be isolated from the main network and wouldn't require you to go through hoops to keep your traffic safe.
