So after 2 weeks of slaving over my first game I was finally done! I was entirely ecstatic....until I saw its file size.

770 Megabytes

For a simple numbers game, that was way too much and I created an empty unity project as a test and that was also over 700 megs

Why is an empty Iphone project this large?

Note that mobile builds sometimes bundle together versions for multiple different phone models for an app store submission, where the store handles distributing just the right version for a given player's phone out of that collection, along with additional info that's just for internal use. So the file size that a player downloads may be substantially smaller than the file size you upload. Always test to confirm. \$\endgroup\$

    \$\begingroup\$ Are you making a development build with all of the debug settings enabled? This can increase your build size a lot as the build will include debug symbols etc. Also, make sure you are using the latest version of the Unity branch you're using in case it's an engine bug. \$\endgroup\$
