Thank you, that's a good point, actually. Keeping things lean can be quite tedious and tricky in some cases.

The first thing I had in mind was frameworks like PhoneGap, Exponent and the likes. I wonder if these have a big impact on app size.

But it's certainly true that it's not always extra stuff to slap on that makes things bloated. Could just as well be the stuff you don't go out of your way to keep out.
