How to tell if mobile apps are true duplicates
I have a lot of mobile apps and an iPad and iPhone, and I want to clean out the old duplicate apps but am concerned that by removing one it will really only remove it from one of the devices; this is not the issue of the duplicate app which is numbered .1, .2 etc. after the name and version number = this is the 'same' app which has a different version - and I don't know which is the iPad one or the iPhone one, so don't know if I can remove it - for instance, I have
"Wash Post 3.0.4.ipa" and "Wash Post 2.7.1.ipa" -- the name is the same, but the number is different. Would I be safe removing the lower numbered app? I don't know why the numbers are that different, either.
