I have been using AnySoft, but its so buggy at this point, its effectively unusable. Judging by the github, its been in this state for at least a year now. I tried to downgrade to an older version in the hopes of fixing it, but couldn’t get it to install. Is there any better options?


Flickboard is also worth checking out if you like this style of typing. It’s on F-Droid.
The dev compares them like this in the README:
I have used Flickboard too and I like both of them.
Flickboard is more advanced and supports a lot more customization. For example, it has macros which expand to symbols and text. You can create shortcuts for your email, math and currency symbols etc.
IME thumb-key is minimal, updated more frequently, and looks better out of the box. So I prefer it.
