You are correct that the final size can be estimated pretty closely by checking the sizes of the files in the application bundle. However, Apple will encrypt your binary, so in most situations your zipped application will be a bit smaller than the one on App Store.

I checked this link out, I have not attempted to try and compress anything as of yet. I did a search within Finder inside the MyApp's Folder, for any ".app" I get three of them, all with same logos except one has a crossed-out-circle overlay-which I assume is not the correct one. The other two are 2.3 Mb and 1.4 MB. ? Please read my detailed followup @Jordan's suggestion, where I laid out my hunt for the size so far. If you have any other suggestions I'm open for comments. Thanks!

Additional Note: "Getting Info.." on the entire file jumped up to 14.5 MB from 11.8 MB after building the Active Release. The [MyAppName.build] folder just inside the [Build] folder has a size of 5.7 MB. Thanks for the help!!

You want the one in the Release folder with the .app extension. The Release one doesn't have any debugger information in it.

Thanks for the help!! That file is the smaller 1.4 MB. So I should add the 1.4 MB ".app" file with all the images ~ 750 KB, and the sqlite database 250 KB to come in around 2.5 MB total. Although it will be compressed during upload, from what I understand the uncompressed size is what Apple reports as the app size and what determines if the app will be downloaded via network or wifi. I'm well under the limit. ** Sure would be nice if Xcode had a compiled App-Size indicator during builds, as important as it is. It would be a lot easier than adding up all the components yourself.
