How much memory does a common app use?

[Pandafox]

I was just wondering where I should try to draw the line when it comes to memory usage.

For example, what kind of memory would apps like "Twitter", "Contacts" or "iBooks" use? (idle, peak, background)

My application had some problems on some devices, where the peaks of 23MB LiveBytes would occur, and idle usage was at about 5MB. (Working with some pretty big datasets in CoreData)

Since then, after some optimization, I get peaks at 5MB and about 3MB idle usage.

My app is pretty much based on tabs and tables, allows the user to search in a database with about ~30000 rows worth of label/url database and the peak of 5MB occurs when capturing and downscaling images.

(memory warnings are handled properly of course)

Is this still considered to be a bit excessive compared to similar apps?
How much memory does your apps normally consume?

As long as you aren't leaking memory and you are responding to memory warnings, 5 mb is fine.
