Maintenance 2.5.0, 20 Feb 19 and OnyX 3.5.8, 20 Feb 19, have been released. They are both made by Titanium Software. I opened both apps and looked at their startup screens. OnyX has 4 areas (multifunction utility) to choose from. Maintenance has 1. Both are the same. I can’t see having the Maintenance app as they are both FREE.
