Titanium Backup hasn't been updated in five years, and I think that update was just to meet requirements to stay on the store. Their last changelog entry is adding the menu icon after Android ditched the physical menu button. There are a bunch of settings that are broken or do nothing due to changes to Android over the decades (TB has been around for so long that it supports Android 1.5).
I've been using Swift Backup as a replacement these past few years. It's closed source but was recommended to me, and I haven't run into any problems yet. Is Neo better in some way, aside from being FOSS?
Yeah, it's twelve bucks to unlock scheduled backups and cloud syncing in Swift Backup, but then again this post is about paid apps. :)
