You’ve been working hard preparing for your launch to AppStore. The final step is getting it submitted to iTunesConnect.
You have to fill in the app details, upload the app icon, localized descriptions and preview images— upload them one-by-one going through your list of localizations for each supported device in English; one-by-one for each device in French; one-by-one for each device in German, etc, etc.
OK, 13 languages.
You have to upload screenshots one-by-one for each device, for each locale. Oh that’s O(n²)
Let’s say you have built an awesome app for iPhone & iPad and now it’s ready for launch.
Question, how many preview images exactly do you have to add?
The answer is simple. For each locale, there are 3.5-inch, 4-inch, 4.7-inch, 5.5-inch and iPad screenshots (and don’t forget the upcoming iPad Pro). There are 5 images in each set, that gives you 5 x 5 = 25 pcs for each locale.
Needless to say, you will have to organize 25 x 13 = 325 preview images to iTunesConnect. Sounds scary right?
