问题
I uploaded my app to iTunes Connect, what I see under "compressed file size" is 222MB. However, when I check the app size on a real device in settings->general->storage, it shows 84.9 MB. Why am I seeing two different sizes here, and which one is correct? If either is accurate, how can I estimate the app size before I submit to app store? I'm trying to reduce the size to max 100 MB so that users can download and instal over cellular. Any suggestions would be highly appreciated!

Go to your app's page on iTunes Connect, select the "Activity" tab, select a build and you'll see a link that says "App Store File Sizes":
Click it and you'll get estimated sizes for different devices.

It is kind of hard to estimate the size of the app for different form factors because Apple uses a method called App Thinning. I think the best way to do that is to check on the every platform on yourself. Or keep the initial package size to less then 100MB.
