> Our apps are blazing fast (<500ms screen loads)

I’m not sure I would consider 0.5 seconds to be blazing fast.

I wish the article went into detail on what these screens do and what a screen load means exactly.

That was my initial thought as well. Anyone know what native screen loads typically are? I’m sure it varies wildly between apps, but 500ms seems like it would be on the slower end of a “fast” app.

For reference, our app is 100% in Jetpack Compose, our screen rendering for both cold and warm are in the average of ~460-480ms. App start is around ~480ms.

If your warm and cold starts are that close I'take a closer look at your measurement methodology. Could be your cold starts are actually warm, or your timing is starting late.
