ELI5: Why does Facebook Messenger and other similar apps on the app store have random 150mb updates a few times a week?

I don't see any difference in the app at all once i update it, why is it around 150mb every time?

Because it's easier for them, and no one really complains about it.

They *could* structure the app so that smaller parts of the app could be updated individually without having to redownload the entire app. Or they could wait longer between updates and roll all the changes up into one 150mb change every 3 months.

But everyone happily downloads those 150mb every time, so they don't really have an incentive to do anything about it. And for them, it's simpler to just ship a new copy of everything any time they make even the smallest change.
