I have finally found a third-party, open-source #Twitter / X app for #Android that still works despite the API restrictions.
This is a passive-consumption app only - no account login, so no interaction. But that's perfect for how I've been using that site the last few years.
If your profile is unlocked, you can import all of your followed accounts. It works very well.
Also, I recently posted about Stealth, which is the same thing for #Reddit but without the following import.
