I could not recommend AnySoftKeyboard to my mum. I could recommend Florisboard, tho.
Openboard is virtually dead from what I can see. So that leaves Florisboard as the only open source alternative (that I know of) that could really be used by the masses. And the world would actually be a way better place if we all opensource freaks could install Florisboard on our family/friends phones and them barely noticing anything weird.
The problem is… no word suggestions yet. It’s been years and we are still lacking what is almost an essential feature of a phone’s keyboard.
I wish I could really work on it, but I lack the knowledge to do so; so I hope I am bringing some attention to the project.
Is there any other alternative I am unaware of?
OpenBoard’s developing is being carried on by one of the original developers: https://github.com/Helium314/openboard
It allows to include an external swipe-type library (proprietary, from Gboard) in case you need it, and it works really well. The only problem is that currently it’s only available on github, so you can only update manually or with obtainium
