How much is a build reduced with pro?

My app is 100M on Android, but it is more than 450M on iPhone. I am looking for a solution to this, but I heard buying pro version is the only solution. So I wonder how much pro reduce build size, generally.
Actually I am using a lot of images in the app. Should I buy pro to fix this? :slight_smile:

Well, i have a same problem about ios before. I don’t know about the pro, but i can reduced the app size by following this optimization. At least i can turn a 1 GB app to about 600MB. Ah, and for your information i don’t use unity ios pro for that.
