As long as you don't need a lot of hi-res graphics. One of the no-frills icon themes installed on my Linux laptop (from which I'm typing) is 170M, just because it has a pack of icons rendered for each of the 8, 16, 18, 24, 32, 48, and 64 pixel sizes.

(And no, vector icons are not equally useful in this whole range of resolutions; you need to lower the level of detail for small resolutions to avoid pixel sludge, and increase the level of detail for high resolutions to avoid the barren look. Still, say, 3 versions in SVG format could be sufficient.)

You don't need "hi-res graphics" in an app.

Why?

Small screen, lots of system components that should get drawn dynamically, etc

A bit reductionist, but I get it, if it were a priority you could do lots with a hundredth the space

Small screen (iPhone) that could also be a medium screen (iPad) or even a large screen (Macbook), no?

Yes but with Vector based logos, and considereing you don't actually need all sizes for most apps there's a lot of margin there

A 6 inch screen doesn't need an 8K logo and all it's variants

Someone was saying that Apple OSes don't do vector logos.

If your app is 5mb to download but then needs to download 100mb of content your app is 105mb.

I have a couple that are honest sub 5mb apps. Some of my favorite apps on my phone. Limited featureset that does what it says on the tin. Loads instantly. Hardly uses battery at all. I wish everything was like this.
