Bless you for not making people use Tik Tok.

I haven’t checked, but yt-dlp supports a ton of services besides YouTube. It probably works in Termux.

if you have an iPhone I use the R Download shortcut and it lets you download a lot of things through the standard share menu

Hit the share button and ”save video” should be there at the bottom.

Depending on whether the video creator has allowed it, long press on the video and select “save video”.

My friends screen record the video and send that because I refuse to click tiktok links. I still don’t watch them.

There’s also a telegram bot

Usually you can just google tiktok downloader, paste in the url and download it. Its possible those services have died since I last checked though.
