It has been over a year since I left Twitter and I don't miss it. I have been using mastodon and it has been a much more enjoyable experience. I am not subjected to spam, scam, advertising and hate. It takes a bit to get accustomed to, but I have a wonderful feed with people who post and share information that I find interesting or makes me think.
In Linux there are clients (I am using TUBA at this time in MX Linux as a flatpack), Android has clients (I am using Trunks which is cross platform - Android & IOS). It is also accessible via your browser as I haven't found a client there that works as well as the browser version.
