As reported in a reddit post and confirmed in a github discussion, Simple Mobile Tools is being sold to ZippoApps which is known for shady business practices.
It is not yet clear whether they will make the app suite closed source (which would infringe the rights of all contributors since they contributed under the GPLv3 license).
In response to that situation, one of the main contributors forked the project under the name FossifyX and will continue to work on it.
For contacts I like Connect You.
I’ve tried it a few times in the past but have always come across bugs that give me functional issues. I can’t remember exactly what they were right now but give it another few months and I’ll probably try it again.
Wondering if ConnectYou will work with my contact list in NextCloud.
if you use DAVx5 to sync them, every app with contact access will be able use them.
