It's a bit off-topic but you can get user experiemce quite similar to that of Tiktok using Read You rss reader on Android.

You should try out https://scour.ing

It's not exactly a TikTok experience since it serves you a digest of multiple articles at once vs. one article at a time. But, you can tell it what topics you are interested in and it will find recent articles in thousands of RSS feeds that the algorithm thinks you are most interested in.
