It's clear that's probably most of users prefer less amount of updates.
I disagree, I think users consider frequent updates to be an indication that an app is being actively maintained.
The other vital consideration is tnat the App Store search ranking algorithm may prefer apps with more frequent updates.
I think the ideal update frequency is probably “a bit more often than your competitors”.
Every 1-2 days seems rather extreme though.
I don’t believe there is a mandated limit imposed by the review system. Beware that each review is an opportunity for them to invent something else to complain about.
