App Name in Appstore is different than on your mobile device [closed]

Question

I am about to submit my app to the App Store. As you see in the following screenshots, once you open App Store, you could find a very lengthy name of the app. But once you download the app, very short name is shown only. How is it possible?

Answer 1

The name under the app icon on the device is the Bundle Display Name.

By default, the Bundle Display Name is the same as the Bundle Name, but you can set it in Xcode by selecting the info.plist file and setting it in the editor.

The Bundle Display Name does not have to match the Bundle Name or the application title that you set in iTunes Connect, however, it must be similar to the application title that you set in the store or Apple will reject the app.

The app store guidelines:

3.4 App names in iTunes Connect and as displayed on a device should be similar, so as not to cause confusion

Documentation on Bundles.

Answer 2

Only the Bundle ID of the app needs to match. The makers of that app set the name of the app in iTunes Connect:

That's the one that is shown in the App Store.

For the name shown under the app, they set this value in their info.plist:

These names are completely independent of eachother, but, Apple does reject apps where the display name is radically different than the name in the App Store. Main guideline: Don't name your app Waffles in the App Store and Unicorns on the device.

From the App Store Guidelines:

3.4 App names in iTunes Connect and as displayed on a device should be similar, so as not to cause confusion
